Practicality of food packaging technology At present, the food and agricultural products in flexible packaging technology has been widely used dampproof packaging technology, aseptic packaging technology, vacuum and inflatable packaging technology, heat shrinkable film packaging technology as well as fruit and vegetable preservation, and packaging technology. These technologies in the protection of a variety of food and agricultural products are not spoilage, extend the storage time have significant effect, are introduced separately as follows:      1. Moisture-proof packaging technology      Is the incorporation of water vapor must cut off the moisture capacity of food packaging materials or packaging agricultural products, cut off from the outside world the effects of humidity on the merchandise, while the relative humidity inside the packaging to meet the product requirements, the protection of quality agricultural products. Each type of food or agricultural products are critical to ensure that their quality of water, such as 5.5 percent of tea, milk powder 2.25%, when the environmental humidity in excess of its critical moisture when and spoilage due to moisture absorption. Therefore, moisture-proof packaging used. Moisture-proof packaging materials commonly used in PE (polyethylene), pp (polypropylene), PVDC (polyvinylidene chloride), PET / PE and PT (cellophane) / PE composite films, such as materials, these materials are very good moisture resistant packaging and integrated performance, to meet a variety of moisture-proof packaging, barrier requirements.      2. Vacuum and inflatable packaging technology      Refers to the packaged food or agricultural products into gastightness containers, prior to pumping in confined into a vacuum or filling a certain percentage of ideal gas, so as to improve and control the food environment surrounding gas, limiting the biological activity of food to prevent food mildew, to extend the shelf-life. As we all know, attached to the surface of micro-organisms in food, only at O2 can exist under the conditions of propagation, vacuum and inflatable packaging or through rechargeable vacuum into N2 and CO2, which undermines the survival of microbial propagation conditions, thereby slowing food biology of Health of metamorphism. The technology commonly used in dairy products, meat products, tea, peanuts, cake and other packaging. Materials commonly used for PET (polyester film), Ny (nylon), PVDC, EVAL (ethylene, ethylene alcohol copolymer) and to them as the substrate composite film.      3. Aseptic Packaging Technology      Means will be packaging food, packaging containers, packaging materials and packaging materials separately assisted sterilization, and aseptic filling environment sealing a packaging technology. Aseptic packaging of liquid food is generally liquid or semi-liquid food, such as milk, wine, fruit juice and so on. Its characteristics for containers and packaging, sterilization separately, you can prevent heat sterilization time when the cause of food deterioration and loss of nutrients, particularly dairy products and bananas are like mud like thermosensitive food, aseptic packaging can greatly extend their shelf life. Materials commonly used there is LDPE (low density polyethylene, white) / LDPE, LDPE (white) / HDPE / LDPE (black) and PVDC / PE composite film, etc..      4. Shrink Packaging Technology      Are heat shrinkable plastic film package with a product or package, and then heated to a certain temperature, so that contraction of plastic film to shrink, so as to achieve close to encase the purpose of packaged objects. The packaging method is adaptable, compact packaging, the appearance of fine, better product protection, packaging technology, the advantages of simple equipment. Especially suitable for vegetables, fruits, with plate of fast food, as well as general packing method difficult packaging shaped packaging. Shrink Packaging packaging materials currently used mainly in PVC (polyvinyl chloride), PE, PP, PVDC, PS (polystyrene), EVA, etc. Shrink Films.      5. Fruit and vegetable preservation, and packaging technology      Refers to itself in accordance with the characteristics of fruits and vegetables, using the full range of packaging material has a gas-barrier, wet resistance, heat insulation, insulation, shock-proof buffer, antibacterial, antimicrobial and other properties, to carry out both inside and outside of the fruit and vegetable packaging, in the packaging to create a good environmental conditions (temperature, relative humidity, gas composition, pressure, as well as anti-seismic aseptic, etc.), lower fruit and vegetable respiration and maintain their life activity the minimum required temperature, reduced evaporation and prevent microbial infection and mechanical damage to fruits and vegetables for a long time to maintain better eating quality and nutritional value. Materials commonly used there is: PE, PVC, PP, PS, PVDC, PET / PE, Ny / PE and so on.      In addition, in order to protect the food safe, reliable, and also studied abroad there is lot of new forms of creative packaging. At a food such as pest control measures taken so that the natural enemies of food - borers dare not bite through the material being packaged. The United States also invented the cat food packaging materials, put the cat food and oat seeds, plant food mixture packaging. Key technology is to be able to seed germination, growth, food is not degenerate, packaging system to maintain a balance of various factors.

A new concept of food packaging All Products must be packaged, with the rapid economic development and quality of life continue to improve, our food industry is developing rapidly, people's livelihood concepts and consumption patterns, significant changes are taking place, packing in people's life more and more important, on food packaging are also put new demands of this century food market depends largely on the quality of packaging competition. Science and technology, food packaging with each passing day, and food packaging concept also showed the new features, the diversification of food packaging to meet the needs of modern people want different levels of consumer demand; sterile, convenient, intelligent, personalized food packaging are the new fashion; expand the functions of food packaging, reducing packaging waste on the environmental pollution green packaging has become the new century, the development trend of food packaging. 1 Aseptic Packaging As consumers of food packaging fresh features and higher demands, improve food packaging to extend fresh food manufacturers have become much of the important issues covered. At present, preservation, and packaging aseptic food industry in the countries most popular, and their use is not limited to fruit juices and juice drinks, but also used for packaging milk, mineral water and wine. One-third of the United Kingdom has been the use of aseptic packaging of beverages. Canada has adopted the apple juice aseptic process. Developed in Japan as raw materials for calcium phosphate mineral enrichment absorbent paper bag for packaging fruits and vegetables, such as food, so that fruits and vegetables from the mineral to be concentrated liquid nutrient supply, and the absorption of fruits and vegetables release ethylene gas and carbon dioxide. Inhibit the decomposition of chlorophyll, has played to maintain the freshness effect. The United States market with natural active clay and polyethylene plastic bags made from fresh fruit, like a very fine sieve filters, gas and water vapor flow through the bag, so that the shelf life of fruits and vegetables increased more than 1, and the packaging bag can be re-use, easy recovery, the price is not higher than ordinary plastic bags. Aseptic packaging of food packaging at the proportion of larger, such as aseptic milk pouch cheaper prices, product taste better, and kept at ambient temperature a long time, producers, consumers would welcome such a packaging product, the product not only to overcome the geographical constraints of production, but also removed during transport of the cold-chain requirements and is conducive to market expansion. According to statistics, the aseptic packaging of liquid food products more than 70% of global annual consumption of carton aseptic packaging of more than one hundred billion个. At present, there is a variety of aseptic packaging equipment about more than 300 sets of annual production capacity of more than 1,500,000 tons. Tetra Pak, Sweden, Switzerland, the United States and SIG Moreton packets and the United States International Paper cartons are dominating the field of aseptic packaging of three giants. With economic development and people's living standards improve, the demand for convenience foods is bound to greatly increase, will promote the further development of aseptic packaging. 2 green packaging Green packaging refers to the ecological environment pollution-free, harmless to human health that can cycle and recycle packaging. At people on the ecological environment of great concern today, the green environmental protection food packaging has become a necessity. Experts predict that the next 10 years will dominate the world market of green food, and green packaging is a green food consumers at Central passes, it has a shape of green food brand importance. From the coordination of social development and ecological and environmental protection, the countries of the world have to reduce, reuse and recycling of biodegradable packaging as eco-environmental protection objectives and means. At Tsinghua University and Chinese Academy of Sciences Institute of the joint efforts of micro-organisms have been successfully completed with waste molasses as raw materials to produce biodegradable plastic PHB (PHB); use of genetically engineered bacteria to produce biodegradable plastic PHB; by hydrolysis starch as raw materials to produce biodegradable plastic PHB and its copolymer PHBV and PHB biodegradable plastics can be modified and the application of research results. And on this basis on implementation of the international large-scale production on the first third-generation PHA hydroxybutyrate copolymer has hydroxy ester (PHBHHx), by microbial synthesis of biodegradable poly fatty acid alkyl PHA, has an excellent biodegradable, compatibility, voltage and optical activity, its structural diversity, together with the structural changes brought about by the new material properties, to make such food packaging materials at the direction of very broad application prospects. PSP German company recently developed a new technology bubble in paper production, with its production of packaging materials can replace the foam. This type of foam and flour using old newspapers for material, first reported the recovery of the books be broken into, and then beaten fibrous pulp, and flour to 2 than to the ratio of l mixing, the pulp mixture into the extrusion pressure into cylindrical particles. Extrusion process, the role of raw materials affected by water vapor bubbles paper. Bubble of the paper used as raw material, can be required, depending on a variety of shapes to produce plastic packaging. Paper may be a bubble shape, no chemical additives, but also the recovery process after use. Use of modern super-powder technology, raw materials crushed into 10 ~ 25 μm between the ultrafine particles known as, in recent years, study found that the use of ultrafine powder prepared by starch-based biodegradable plastics has obvious advantages. Advanced Micro Devices starch particle size small, uniform, with a great specific surface area, has enormous surface energy with its liquidity and filling significantly improve for the Preparation of biodegradable plastics can be effective in improving the mechanical properties of materials, be able to guarantee the material at the premise of the use of performance and greatly enhance the volume of starch added, which reduce costs, save oil resources, the development of the application of natural starch, biodegradable plastics enhance the rate of very important significance. The United States Agricultural Research Service southern regional center for the use of soybean protein, add enzymes and other agents handle packaging films made from soy protein for food packaging, to maintain good moisture and prevent oxygen to enter, along with cooking and food, both easy to reduce environmental degradation pollution, food and avoid secondary pollution. Indonesia's scientists, the invention of cardboard with algae system technology, with two tons of dried algae, the system can be a ton of cardboard. Made of cardboard by the quality, not inferior to ordinary cardboard. And have done a commercial production. 3 functional packaging With the rapid development of packaging technology, in recent years, both at home and abroad have developed a number of features unique and diverse variety of packaging products, it is refreshing, by the favor of consumers and operators attention. Recently, the United States FDA has approved a UV blocking agent in the United States on food packaging applications. Sunlight contains ultraviolet fluorescent warehouse, and add the product at a transparent PET packaging materials in the UV blocking agent that can effectively block ultraviolet rays to prevent the packaging of goods in the color, smell, taste and nutritional value there is on any changes. Transparent packaging material, will allow consumers know the quality and appearance. Most of the green color in foods contain many of chlorophyll, which is pigment-ray irradiation in photosensitive oxidation reaction will occur, resulting in rotting food. Deal with the German Fraunhofer Institute of Packaging Technology Gold Chinese scientists have recently invented a plastic film with chlorophyll a special method of "staining", subject to such a deal after the film for packaging foods can prevent the Green food color chlorophyll oxidation happen, greatly extended the shelf life of green food. At present, the pursuit of the perfect preservation of the growing functional food packaging has become the preferred target. Singapore to develop and produce a fresh wrapping paper. This paper contains antibacterial, fungicide, apple storage in this paper, opened half a year later, still full of fruit. The other - types of plastic wrap can citrus fresh three month, so that more than 30 days fresh litchi. Yingde United developed the containers and lids at the inner wall of the packaging material used Deaerator through these Deoxidization Materials "eat" the extra oxygen, so as to achieve preservation purposes, the extension of product shelf life. The United States also introduced with oxygen as a function of the composite cap beer cap can be from the beer shelf-life of 3 ~ 4 months to 4 ~ 6 months. Japan's recent success can inhibit the development of a British two chalkiness generated new plastic composite packaging material. This material is a high degree of PP and talcum powder evenly blended, and then by heating after molding into containers. This material itself does not produce, such as HCL and two chalkiness British produce any gas, and when burned can be fixed Absorption other waste generated by HCL gas, thereby inhibiting the emergence of two British chalkiness. American researchers in the food packaging bag was placed on a layer contains a chemical known as AIn090rb plastic film, packaging removes oxygen, so that food packaging can be a long time does not degenerate. The chemical substances in special light before irradiation, has been in a dormant status. When receiving special light irradiation, the chemical began to appear. That is to say, in the packaged food, the need for complex Deoxidization treatment, as long as at the last line of food packaging processes, with a special light irradiation can be. Russian experts at packaging materials added to polymer dehydration acidification objects, a variety of mineral salts and enzymes material. Rich in these substances the surface of the packaging bag can be absorbed by the packaged food in excess moisture, kill bacteria, thus improving the internal environment of the bag. At the same time, additives in the enzyme, but also regulation of food odor, for the nutritional content of food to create a living space. 4 smart packaging Intelligent packaging used thermo-sensitive photoelectric, humidity, gas-sensing features such as packaging materials from composites. It can show the packaging space temperature and humidity, pressure, and sealed the extent, timing and other important parameters. This is a promising feature of the packaging. East Hi-Tech Company Limited Sichuan well recently successfully developed a novel anti-counterfeit packaging film. This anti-counterfeit packaging films at the merits of its colorless and transparent, on the merchandise bags, cartons, tin, glass bottles above pattern does not have an impact. At light, can clearly show that can not be counterfeit laser holographic patterns and language. If the merchandise will be used to automate the packaging production line, we can make the overall anti-counterfeit merchandise effect even better. This novel is a colorless anti-counterfeit packaging film plastic film, thickness of 10 ~ 100μm. Films on laser holography by a tailor-made metal version at its imprint on a variety of embossing depth of indentation patterns and characters, as well as two-dimensional, three-dimensional geometry, three-dimensional sense of strong and structured. Indentation depth is generally convex. Warning prompts food packaging can be turned, separated by three layers: the inner layer is a porous layer, it has a direct contact with food, if food is infected with certain diseases can cause bacteria, these bacteria will be able to pass through porous seepage layer, middle layer of arrival. Middle layer that contains a gel, bacteria can gel with the antibody of a chemical reaction, thus changing the color. Then bacteria will enter the most outer layer, rather than the surface of another on the role of antibodies happened to X shape spread and let the consumer be able to find food has perished. Australian packaging materials experts developed a new electronic warning to the packaging, when the food easy to corruption at high temperature to heat, its quality can not be guaranteed, the packaging will be changing the color sensor, the electronic chip that is issued a warning. Electronics Packaging Technology also about the lack of fresh measures to help food exporters, manufacturers go through a satellite tracking, monitoring of food sent abroad during the transportation of temperature changes, so that their products can safely be exported to foreign countries. Sweden, a first for biology, developed an intelligent sports drinks packaging. The packaging looks like a sports lid locking push-pull, from high-density polyethylene and polypropylene production, with a plastic coating containing aluminum enclosures have freeze-dried material, which was sealed at the lower part covered. 28mm bottlenecks bottles are PET bottles, to drink at when first getting a sleeve to protect the piston ring sets, or by pressing the upper cover. When the press covered put, when there is a mechanical seal punctured aluminum foil, a small amount of freeze-dried tablets into the drink, shake the bottle so that freeze-dried tablets dissolved in the drink and activate the original biological, put the top back cover can be drinking, closed after drink. 5 Convenience of packaging Convenience food packaging and food packaging is also the aspect of development can not be ignored. Consumers need to open, sealing are more convenient packaging, food packaging is also necessary to give life more convenient. Convenience food packaging is the new trend of development. For the convenience of the consumer consumption, the use of solar energy, chemical energy and the principle of metal oxide, so that the food in a short period of time automatically achieve automatic heating or cooling to meet the outdoor workers, tourists, elderly people and children's needs. Such as the United States self-cooling beverage cans containing compressed CO2 has a small container, open at the size of the rapid expansion of CO2 can make at 9s beverage temperature dropped to 4.4 ℃. Japan's use of quicklime mixed with water the principle of heat production, the development of the self-heating sake packaging, will be available at 3min can Sake heated to 58 ℃. Nissin metal oxide using the principle of the development of a self-heating canned convenience, the tank can 5min with cooked noodles. Have food insulation paper, can be light energy into thermal energy, paper packaging put on the place of sunlight can be heating up the food. Japanese food manufacturers to produce the self-heating or self-cooling cans, primarily for coffee, soup, congee, noodles, sausages, rice and other food and beverage packaging, has been produced in quantity and the market. This use of composite cans are plastic or aluminum, the upper part of loaded food or drink, there is at the bottom of the heating or cooling device. Heat through water mixed with quicklime and produces heat to achieve; refrigeration is by water and ammonium nitrate or ammonium chloride to obtain a chemical reaction happened. 6 Personalized Packaging With the continuous improvement of scientific and technological level, more and more similar products tend to homogenization, the competition among enterprises, in a sense, has transformed into the image of our competition, the design is not just a simple visual stimulation and, more importantly, create a Product and design information exchange and emotional experience, which for a variety of personalized packaging design to create more space. Changes in lifestyle, economic capacity has also made it a stronger sense of the pursuit of characteristics. Food packaging more personality, and development will have the market to meet the diverse needs of consumers. Personalized food packaging are the inevitable trend of development. World-renowned beverage brand Coca-Cola Company will be the packaging and brand personality as a positive relationship. Careful consumers can be found, although each time it is reflected in the package design change is not great, but each time the changes in the market can cause a sensation. BOCOG announced in Beijing attracted worldwide attention in 2004 Beijing Olympic Games emblem, the same day, 110,000 printed with the emblem of the new limited edition Coca-Cola cans exquisite Memory also officially listed. Coca-Cola spent less than a month to complete, from product design to the official listing of its high efficiency at surprise people, Coca-Cola Company became the top sponsor of the Beijing Olympics in the first Olympic Games was honored to be authorized to use the new emblem of the company . Memory tank of its design combines the Olympic logo, Beijing, China, elements, elements and Sport event elements, the new emblem will be integrated into one of the Temple of Heaven, Beijing highlights strong regional characteristics. Century-old history of Watsons Water maker launched in 2004 at the new products listed one, its quite refreshing new packaging will allow the consumer brighten: bottle streamlined, concise fashion green packaging and the unique double bottle cover design; put distilled water into a unique taste and unique style of fashion products. As we all know, now people are like at the supermarket to buy food, so easy to buy; but it is precisely at the supermarket, the kind of food are often placed together, then the most able to attract consumer attention, apart from product brand and apart is the quality of the packaging. Strong impact on product packaging often be able to purchase consumer awareness about. The major manufacturers is also found this, have started packing up at their brains, and strive to greedy pleasing packaging to attract consumers, and similar products in competition, was the timing. Food can not be separated from the packaging, packing a direct impact on food quality, grades and markets. Food packaging industry in our country want to integrate into the new trend of international food packaging, to increase scientific and technological and capital inputs, the development of more innovative features unique, modern people can meet different levels of consumer demand, and also conducive to ecological and environmental protection packaging products.

How to achieve food smart packaging Holiday period, generally a lot of food at home will be saved. Now supermarket food packaging, food can only be easy to play instructions and the role of the prevention of food contamination. People usually think, as long as the packaging of food in the shelf-life period, it should be safe, but sometimes not the case. In order to ensure food safety, so that consumers do not eat spoiled food, the scientists can come up with some metamorphic instructions Whether or not a new type of food packaging technology and extend the shelf life of food packaging technologies, which collectively, the "active packaging technology," or "smart packaging technology" . Unfortunately, our country is currently far behind in this regard. ■ "smart" food from the "active" packaging Food for the delay due to oxidation and deterioration, the current common practice is in the packaging into a powder inside the packet, the use of iron oxidation process spent inside the packaging of oxygen. However, some customers in the food to see which one printed "勿食" the words do not have to kick on the packet, and the new packaging is coupled with a layer of wrapping paper in "sucked" Materials oxygen, which can make them feel comfortable a lot of . Another instance, a number of fresh food at low temperatures necessary to preserve, or else the bacteria will be active inside, and cause food deterioration. Affixed to the packaging instructions on time and temperature of the new tags, one of the chemical composition at higher temperatures when the polymerization occurs, the corresponding tag will be light and shade of the color change, thus customers can know at what temperature food storage, storage How long, how in the end the degree of freshness. According to the United Kingdom, "New Scientist" reports, such as "active packaging" technology, already in the United States, France and other places use. Many companies recognize that customers understand that the provision of fresh food to their correct, and its potential commercial benefits are enormous, the use of new technologies to develop additional cost compared with, but are "pale into insignificance." At present, some companies are developing the United States frozen food preservation instructions packaging, new packaging can be monitored to meat, fish or vegetables due to improper refrigeration decomposed metamorphic released gases. Different fresh fruits and vegetables needed for the concentration of oxygen and carbon dioxide are different characteristics for this packaging technology is also developing into. California company is developing a packaging film, this film can change its permeability with temperature capabilities, meet the needs of different fruits and vegetables of different oxygen and carbon dioxide necessary. In New Zealand, researchers at the development of a fruit packaging, this packaging instructions such as peach afraid afraid of pressure squeezing the fruit when cooked. Food Technology researchers estimated that in the coming 20-40 percent of the food packaging will be the application of "active packaging" technologies. ■ Whether or not food metamorphic instructions The researchers found that food packaging, some materials can absorb oxygen bag packaging; Some Materials with the Food and metamorphic gases produced by the interaction time, change color; some material change in temperature will change color and so on. If the use of such materials packaged food, it helps prevent oxidative deterioration of food, or provide consumers with more food safe Whether or not information. As a result of these active materials have a display of food packaging safety feature, so much the company is to research various forms of "active packaging." France's "Fujio price" supermarket chain is much fresh food on the use of a known as the "time temperature instructions" of the packaging technology. In fact it is a tag, you can show the food at a temperature kept many Long time. Labels such as used in target shooting, there is much transparent trap circle circle, the center of the ring contains a chemical substance. Such chemical substances over time and temperature difference in the polymerization by the transparent black. If the packaging of food at low temperature to maintain status, the chemical polymerization reaction is very slow, once the temperature increase in polymerization will be accelerated by chemical substances will be transparent black. Up because of food bacteria with temperature and time increased, so the extent of chemical substances will darken more and more serious. When the inner dark, it means that the food is no longer fresh. Consumers can change the color of this tag to determine whether the foods at high temperature state of preservation for a long time. Researchers another food safety instructions packaging technology, is a dye-doped plastic wafer, through the food bags and packaging which play a role in the release of the gas, indicating whether the deterioration of meat and vegetables. Add this plastic film food packaging bags, if perishable food packaging bag, it will release a gas, so that plastic film to change color. Consumers under the color of plastic films will be able to know whether the foods metamorphism. ■ extend the shelf life Different fruits and vegetables required at a certain concentration of oxygen and carbon dioxide can be fresh, and so the oxygen and carbon dioxide concentration in the sealed packaging bag is difficult to control. Because when the temperature is high, the packaging bag of fruit or vegetable will consume more oxygen and release more carbon dioxide. Therefore, if not regulated, the shelf life of food is bound to be affected. In order to solve this dilemma, the United States Menlo Park, Calif., company is studying a so-called membrane Intelimer packaging. This film at the temperature changes, will change their permeability, so that different foods to keep in the best proportion of oxygen and carbon dioxide concentrations under. Slow down the rate of food deterioration Another method is to use an oxygen scavenger to remove oxygen, control of the packaging bag of the air environment, thereby avoiding deterioration of food oxidation. The current commonly used method is put in the food packaging bag with a sachet of powder, through the iron consumed oxygen packaging bag. However, this method is obviously insufficient, because pouch on the "no eating" signs to warn consumers easily lead to resentment. To this end, the United States, New Jersey, a sealed gas company is the production itself can be an oxygen bag to remove the material. Materials such as iron, as capture and consumption of oxygen packaging bags.

Food packaging safe Eight Notes Food packaging to ensure food safety and hygiene as an important means to be a more extensive attention, food packaging should pay attention to the following areas: First, know the characteristics of the food itself and the requirements of the protection conditions should study the impact of major components of foods, particularly those affecting the fat, protein, vitamins and other nutrients-sensitive factors, including light, oxygen, temperature, microbiological and physical, mechanical the impact of factors such areas. Only master had been packaged food biology, chemistry, physics characteristics and sensitivities to determine the requirements of the protection conditions, to determine the choice of what kind of packaging materials, packaging technology for packaging operations in order to achieve their protective function and the appropriate extension The purpose of the storage period. Second, research and master the performance of packaging materials and packaging and conditions of the scope of application of a wide range of packaging materials, performance varied. Therefore, only know at a variety of packaging materials and containers of packaging performance, can be in accordance with the requirements for protecting a packaged food selection to protect the food flavor and quality, while the value of merchandise with their body and become a reasonable packaging General packaging materials. Third, information on the packaging techniques for a given food, in addition to need to select the appropriate packaging and containers, we must also adopt the most appropriate method of packaging technology. The same type of food can often use different methods of packaging technology to achieve the same or similar packaging requirements and effectiveness. For example, for oxidation of food, to be used in vacuum or inflatable packaging, can also be carried out inclose Deoxidizer packaging. But sometimes in order to meet the set requirements and the effect, to adopt the specific packaging technology. Packaging technology of choice with the choice of packaging materials is closely related with the packaged food market positioning factors such as closely related. Four, research and know the merchandise market positioning and flow of merchandise regional conditions of market position, mode of transport and flow of regional climatic and geographic conditions, such as food packaging are designed to be taken into account. Domestic sales of goods with different countries for the export of merchandise packaging and decoration of their different requirements, different modes of transport protective packaging requirements are also different. On food packaging, the circulation of commodities Change regional climatic conditions is crucial, because the internal temperature of food chemical composition changes, food microbiology and its packaging material of the barrier itself has a great impact. Friday, research and know the overall structure of the packaging and packaging materials for food packaging materials should be aware of the impact of additives to the food ingredient transfer, as well as certain components of food packaging containers to infiltrate and Absorption of circulation, etc. the course of the effects of food quality. Six, reasonable structure design and decoration packaging design in accordance with the necessary food requirements of the protective packaging is expected to cost, packaging and other aspects of traffic conditions in a reasonable package design, including the container shape, strength, structure, form, size, sealing mode design, the packaging should be structured as far as possible to save materials, save transportation space and in line with the trend of the times, avoiding excessive packaging and deceptive packaging. Packaging and contents should be designed to adapt to Products, so trademark eye-catching, concise language, rich in bright pictorial visual impact, and can cater to the targeted consumer group preferences. Exports should be noted that the national consumption habits and consumer groups to avoid the taboo. Seven, master packaging testing methods qualified merchandise must have a qualified packaging, merchandise Detected In addition to testing the product itself, the packaging must also be tested in order to enter the circulation after passing the area. Package test items are very many, but not every packing must conduct a comprehensive Detect. The specific packaging which really want to test, should be the characteristics of the food contents and sensitive factors, types of packaging materials and its national standards and regulations requirements. For example, canned food cans often determined to be within the coating dissolves in the food situation, deoxidization packaging packaging materials should be measured rate of oxygen, moisture packaging packaging materials should be measured, such as water vapor transmittance. Eight, master packaging standards and regulations in the packaging operation should be strictly comply with national standards and regulations, exports of the importing country should also comply with relevant standards and regulations. The only way to ensure the supply of raw materials from the packaging, packaging operations, circulation of commodities and international trade, such as the smooth flow. As the market economy and international trade development, packaging, standardization, standardization, more and more important. The only way to make our merchandise to go abroad to take part in international competition in the market.

Packaging printing industry in 2008 to maintain solid growth Over the past 10 years, the Chinese packaging printing industry are higher than the annual growth rate of GDP growth. However, in 2008, has experienced the challenges of the international financial crisis package printing industry is not able to maintain a relatively high growth rate it? The overall state of the industry and how? To this end, the reporter interviewed a Chinese printing and packaging equipment Printing Industry Association Branch Secretary-General Li Zhiwei.      "Judging from the current aggregate incomplete data, in 2008 the packaging printing industry in China has maintained a double-digit growth rate." LI Zhi-wei said that due to geographical position, firm size, operating the different customers, the second half of our country in 2008 packaging printing enterprises by the international financial crisis will affect the degree are not the same. Most affected are the main export products to make processing of packaging printing enterprises, especially export-oriented enterprises in the Pearl River Delta region. "These companies have a fixed overseas orders are to do the export of printing and packaging business, are occupied by high-end product market, therefore, affected by the larger."      "However, the packaging printing industry economic slowdown, are incomplete because of by the international financial crisis." He added that "in fact, the trend from the first half of 2008 has felt the impact of many factors . "      He said the continued appreciation of the yuan, so that the printing of corporate profits, loss of exports in the world competitiveness of the market weakened. Monetary policy tightening, so that in particular small and medium-sized private enterprises are capital-chain challenges. "Labor Contract Law" after the implementation of the industrial chain in the bottom of the Packaging and Printing business management costs and labor costs rose rapidly, and are subject to greater stress.      In addition, the first half of 2008, paper prices are rising, or having the largest white board paper, rose 1,000 per tonne yuan packaging printing enterprises by making a tremendous impact - because packaging printing enterprises as customers want to advance the cost of materials, which funds resulted in cash flow problems. Finally, can barely maintain the large enterprises, a number of small businesses, particularly those engaged in processing a small corrugated box factory on the unbearable, forced to cease operation.      Industry has reached a critical period of reform and restructuring, export-oriented enterprises go? "I fully agree with the printing industry in Hong Kong Chamber of Commerce chairman of the Mainland Yang Jinxi proposed development strategy for Hong Kong companies: one to the north to open up the domestic market; we need to stick to two export markets, lower production costs, enhance their competitiveness; three to Southeast Asian development; four want to return to Hong Kong, and change management. "Zhi-Wei Li said.

Diversified flexible packaging of food before the road bright future Food production needs of business-to-flexible food packaging needs of users than the health needs, therefore, food production is concerned with the selection Materials hygiene certification standards. Moreover, taking into account the domestic food packaging safety certification is not particularly sophisticated, Unilever will not be considered only GB certified packaging material. General requirement is that as long as food and direct contact with the material, whether it is single-layer structure or a composite structure, including additives, glue and printing ink, must be through the FDA or EU certification standards. Otherwise, even the most competitive prices are also not select. Possible, we will select the most reasonable structure and materials, rather than the most expensive or least expensive packing material.      Achieve this requirement is also very simple. First, the flexible packaging requirements have food or moisture resistant barrier properties or other properties; Secondly, the flexible packaging is to ensure food shelf-life of the book to achieve standards; Third, the flexible packaging machines have adaptive, that is to say, can Factory production necessary to achieve the intensity or other properties; Fourth, the flexible packaging can be achieved if the needs of the market, because market demand is the demand from consumers.      Food quality and stability, not only from the stability of the food itself, but also from the quality of the stability of the packaging. This is not a mere formality simple what the ISO or other standards can represent, and this comes from the supplier's management and implementation efforts; With the global economic development, consumer demand is changing and developing, resulting in available to the consumer products and packaging must also be change and development. Moreover, the development of packaging want ahead of consumer demand, so that we can drive and lead the consumer. This requires one thing: innovation. The direction of innovation, as was mentioned above, we must in order to enable consumers are more convenient to use. Of course, here, have a prerequisite: Innovation must also provide a better profit to the enterprise space. Corresponds to market demand, flexible packaging development must also be the speed of acceleration. Service not only from good quality, it is equally important is how to provide the most in the shortest possible time to meet the requirements of packaging products. The market will not wait, first for the win.      Development trend of food packaging in order to meet the food requirements of the various functions, an increasing number of new materials have been developed, to reduce costs at the same time, you can provide better protection function; flexible packaging is a fatal defect should not have covered as has re-sealed containers as performance, although it must have the flexible packaging market with the re-closure function, such as flexible packaging lidding film on the jelly, but it is in the process or the supplier of food manufacturers, will the cost of such packaging creates prohibitively high ; another kind of market is the re-closure zipper packaging bag packaging, which apart from sealing the packaging open to question but not such as can be at the organ-type BAG bags on. Therefore, how to achieve further closure performance, and at the same time through a small investment will be able to transform in order to produce the corresponding product, has become an urgent need to see results; We look forward to China's food hygiene standards could be improved and systems, At the same time, from the source material on the saw in line with the hygiene standards of food and packaging materials be produced. Security, the law required, but also required a trustworthy standards and integrity. Another big flaw in flexible packaging is the lack of stiffness. Thus the lack of hard-packed shelves display effect. To improve the direction of performance through the material itself or the packaging in order to achieve improvements in the form of better stiffness, or with other packaging materials with hard to achieve the corresponding effect? These are to be further research to explore flexible packaging business.

At home and abroad to develop the characteristics of flexible packaging market At present, China, Jiangsu, Wuxi, Changzhou, for example, Wuxi, Changzhou has been approved by wholly foreign-owned, joint venture packaging printing more than 120 enterprises have registered capital has reached 6 billion yuan. The momentum of development requires that we must attach importance to the development of the packaging printing industry, modern packaging industry, the four pillars, paper, plastic, glass, metals, paper products, plastic soft packing the fastest growing.      1. Vigorously develop paper-based packaging printed matter      Focus on the development of low weight, high strength, lightweight high-grade cardboard boxes, folding cartons, to the gifts, the color of direction. First of all, is mainly paper packaging folding carton will have a larger space for development, followed by the application of multi-layer cardboard composite materials more and more widely. Users of paper products because of the quality and performance requirements more and more high, resulting in multi-layered material has further increased usage trends. Such as wine and food boxes are mostly used 2 or 3 layer composite board material, paper for the multi-layer substrate material (4 ~ 7 layers), require a higher barrier at the paper packaging (such as beverage cartons) areas be more and more widely used.      2. Vigorously develop the Paper Packaging      Paper and plastic packaging & printing industries are the most widely used two materials, and long-term coexistence. In food, medicine (our country has more than 6,000 pharmaceutical enterprises with annual sales of 1200 billion), health care products, dairy products, cosmetics, detergents and many other fields, plastic flexible packaging has played an increasingly important role. At present, the world of plastic packaging products showed the following characteristics: a new type of polyester packaging more promising; new type of degradable plastics concern; foam plastic Zero attention.      Domestic emphasis on the development of plastic packaging has the following aspects: enhance the protection of the performance, extend the shelf life of high-barrier packaging material, such as co-extruded high barrier development and application of composite films, etc.; aseptic packaging, antimicrobial packaging film, resistant to radiation Packaging Film Development and Application: apply to electric cooker, microwave heating of the packaging material; apply to grain and other agricultural products stored in modified atmosphere packaging packaging materials controllable; electromagnetic shielding composite film used, etc.; Web and Sheetfed Gravure Products , according to the needs of the market will have a larger development.      3. Pollution-free green packaging by more and more importance to society      At present, China's packaging printing enterprises are moving in the direction of a healthy and orderly development.      Today on the U.S. market about 20% -30% of consumer goods is a form of flexible packaging. Promote the flexible packaging market share expanding factors are blocking sheet structure and economic performance of the advanced nature of the effect of high quality Flexo. Among them, the flexible packaging printing market share in the trademark huge, the market of metal and glass packaging containers constantly give way to PET and other rigid plastics such as flexible packaging materials. The next 2-3 years, standing pouch packaging flexible packaging industry will be the most dynamic markets.      The United States has been the printing industry Flexo Printing as the first choice for flexible packaging, Flexo Printing chose yes because at small and medium-sized volume, the overall cost less than gravure. Drive the development of flexible packaging has the following main factors: the food, cosmetics and pharmaceutical products Aluminum composite film packaging has become a trend; drug use disposable packaging growth; consumers on the domestic demand for convenience foods rising. American businessmen in order to attract potential consumers to buy the same type of products, will adopt a different form of packaging. Such as tuna, cereals do have aluminum, folding cartons, flexible packaging and other forms version, this one to printing relatively small, so that the flexible version more acceptable than gravure.

Abroad, strict requirements of food packaging materials and printing In the eyes of foreigners, food packaging and food quality are equally important. Food packaging is the "jacket", once the problem it appears, food safety will also be under threat.      Printing should not be too fancy      Bright color of food packaging, to attract more consumers, but is printed on the packaging of colorful patterns, it may be hazardous to health.      In Japan, "Food Sanitation Law" explicit requirements for food packaging should not be too fancy, but also printed food packaging must be used when specialized ink.      "On food packaging bags often want printed on the name, composition, pattern, language and other publicity information. Printed on the bag on these substances, it is possible contamination of food, causing food safety problems." Japan is responsible for food safety inspection by a member of staff told "Life Times" reporter, in Japan, all food packaging, must be replaced by toluene Prolamin ink ink, such ink relatively stable, not easily generate volatile harmful substances. In addition, children's food packaging should not too much color, this is also in order to control ink usage, and packaging have a segregated inner membrane. Reporter noted that many Japanese children's food also included toys, but toys are at the other outside food bag gift packaging, and will definitely not like home, like on the food bag inside.      Japan's "Food Sanitation Law" also stipulates that food packaging must be tasteless. Prior to a number of businessmen in order to attract consumers, to create a number of children have scent bags, by the detection of one of the volatile substances containing excess, so the parties concerned to prohibit use it to packaged food.      Plastic bags marked with the heating temperature      "Your food safe? Whether or not qualified to take a look at packaging it!" This is the Canadian Food Inspection Agency Federation used to remind consumers of the sentence.      Canadian law on food packaging where there is a clear states: "The food packaging physical indicators and elements must comply with the standards, the potential health hazards of the material, will never be allowed to packaged food." Canadian Food Chemical Safety Board is responsible for the detection of substances , Food and Health Authority of packaging materials into the packaging market regulation, if the packaging problem, or because the packaging may cause security issues, it will immediately recall these packaging producers and strict punishment.     Unlike most countries, Canada is also a lot of plastic packaging, especially the supermarket, people eat fast food items are a lot of plastic tray to add a layer of plastic film for packaging. In this regard, the Canadian Food and Packaging Materials Health Authority requirements, a packaging loaded foods should be within the specified weight. In addition, the ordinary food bags can not be used to hold the temperature at 50 degrees Celsius for more than food. On food packaging must be marked with the maximum temperature can be achieved.      Canada also paid attention to some details from up to ensure the safety of food packaging. For example, a number of Canadian regular plastic tray in the heating consumption of fast food products, but the old-fashioned plastic packaging trays at ambient temperature under the quality of instability, when heated to the release of harmful substances more easily. In this regard, food and packaging materials to health authority requirements on manufacturers in the food stamp distinct tags, which specify the packaging can be used microwave heating, which can use conventional heating cooker, which can not be packaged with heating.      Because of the stringent requirements of packaging materials, the Canadian scientific community continue to introduce new packaging materials, such as the ability to detect bacteria in food packaging, can extend food shelf-life of the new high temperature resistant food packaging. Food packaging material progress, in turn, promoted the Canadian development of food packaging safety.      Food paper bag must be installed      British people are very particular about the packaging of food, security and environmental protection are their primary food packaging requirements. "Foods to choose paper packaging," which in English has become a lifestyle issue. Supermarkets, cartons, paper bags, paper tube, paper cans of silver, grain processing products, flour, rice, potato powder, snacks are on the paper bag, paper tank; scene produced food, such as roast chicken, pigs, etc. elbows are also fitted with a paper bag to the; a variety of beverages, if the juice, vegetable juice, milk, yogurt, etc., it is to use the carton packs. Restaurant, food packaging never use plastic lunch boxes, leaflets are used for paper and paper bags of food.      UK Food Standards Agency is responsible for food packaging, a person in charge told "Life Times" reporter, the paper is the most safe food packaging, as opposed to plastic packaging, the paper packaging is relatively stable performance, it is not easy because the environment, changes in temperature cause harm the body's chemical substances, and can recycling, reduce environmental pollution. English food paper packaging has been specifically developed, has good moisture and freshness and to avoid optical activity, can effectively prevent bacterial invasion and slow deterioration of food, have water, oil, acid, deodorant and other characteristics. In addition, the United Kingdom Food Standards Agency has a special department to monitor and control of food packaging, packaging must be printed on request "qualified tag", and indicate the heat-resistant temperature.      Of course, the plastic packaging in the United Kingdom also has a lot in order to guarantee security, the United Kingdom are very strict gatekeeper. To mineral water bottles as an example, each bottle must be divided into bottle, cap, label three parts, namely, detection of its lead, cadmium, mercury, chromium and other chemical content, there is a part of standard will not be able to use. Of course, most of these plastic packaging biodegradable materials selection, so the cost of more expensive, with the health, safety paper packaging compared to seem slightly more expensive.
