Plastic packaging plays a major role in food packaging

according to data, the amount of plastic used in food packaging accounts for 1/4 of the total plastic output. In supermarkets and shopping malls, many food packages are made of plastic. The plastic inflatable packaging of puffed food can prevent moisture, oxidation, fragrance, sunlight and extrusion, but such a large packaging is a great waste of resources; There is also the packaging of instant noodles. Plastic packaging is far more than that of paper bowls (or barrels). The sales price of bowls or barrels of instant noodles in the market is generally 1/3 higher than that of packaged instant noodles of the same quality. Because this packaging method is convenient to eat, especially when traveling, it can be eaten directly by boiling bubbles after opening the cover, and there is no need to bring other containers, so it is very popular with consumers

according to the latest market forecast report, the consumption of plastic packaging for food and beverage in Europe has increased in recent years and the next few years. By 2007, the market sales of plastic packaging for food and beverage in Europe will increase from $4.91 billion in 2000 to $7.15 billion, with an average annual growth rate of 5.5%. Analysis of insiders: the fastest growth rate of plastic packaging sales of food and beverage in the European market will be the PP packaging market, in which the average growth rate of thermoplastic PP will reach 10.7%, transparent PP will increase by 9.5%, followed by pet, with an average annual growth rate of about 9.2%, while the growth rate of foamed PS and soft PVC market is the smallest, and may even stop growing. France (18.7%) is the country that uses the most plastic packaging materials in the food and beverage industry in Europe, followed by Italy (18%) and Germany (17.2%). With the improvement of people's living standards, new packaging technologies, products and materials continue to emerge. However, at present, the new food packaging popular in the U.S. market is mostly plastic packaging, which mainly includes high-temperature sterilization plastic cans, high barrier material food packaging, sterile packaging, flexible packaging materials and container packaging

in the beverage market, plastic bottles, especially PET bottles, are the most important and eye-catching packaging. In the carbonated beverage, water and beer markets, there is no paper packaging market at all; In the fruit juice market, compared with plastic containers, paper composite containers have a relatively close market share; PET bottles have appeared in the Baijiu market. For example, pet plastic bottles have been used in all Jianzhuang liquor produced by Wuliangye Group. Plastic beer bottles are also under intensive development, and products have been launched in the United States and Europe. Plastic bags of soy sauce have also appeared, and plastic barrels of soy sauce and vinegar have broken the dominance of glass bottles. Small packages such as monosodium glutamate and pepper powder are basically the market of plastic bags, and paper packaging is rarely used

at present, there are mainly several kinds of plastics used for beverage packaging: first, PE. PE is the largest synthetic resin in the world and the largest plastic packaging material in consumption. PE products are divided into low density, medium density and high density. Among them, HDPE has high crystallinity, good hardness, air tightness, mechanical strength and chemical resistance, so it is widely used to blow molding into hollow containers such as bottles. Using the good heat sealing performance of PE, the containers made of various composite materials can contain lemon juice, fruit juice and other beverages. Second, PVC. PVC can be roughly divided into three categories: hard products, soft products and paste products. PVC bottles produced by injection and blow molding have no seams, and the thickness of the bottle wall is uniform. They can contain aerated beverages such as Coca Cola and soft drinks. PVC bottles produced by extrusion and blow molding are only suitable for containing fruit juice and mineral water. Third, pp. Because of its high transparency, smoothness and good processability, it can be compounded with other materials to make a variety of beverage packaging containers. Fourth, pet or PETP. PET bottles produced by biaxial extension blow molding have good transparency, high surface gloss and glassy appearance. They are the most suitable plastic bottles to replace glass bottles. In recent years, the production of PET bottles in China has developed rapidly and is widely used in all kinds of tea drinks, fruit juices and other beverages that need hot filling. Now it is also used in the packaging of Coca Cola. Fifth, PVDC. This kind of material is characterized by softness and extremely low permeability, water permeability, freshness preservation and fragrance retention. First of all, background information: polimotor 1 is good, and it is a good heat shrinkable packaging material. Cellophane coated with PVDC and then compounded with PE is often used to package orange juice. In addition, it is coated on nylon or polyester and then compounded with PE to become a variety of beverage packaging containers

some experts pointed out that PVDC film will gradually become the mainstream material of food packaging in China. PVDC film will gradually become the mainstream material of food packaging in China. In addition to the general properties of plastics, PVDC also has excellent self extinguishing, oil resistance, flavor retention, moisture and mildew resistance. At the same time, it also has excellent printing and heat sealing properties, which are widely used by food manufacturers. Among the current types of meat products in China, ham sausage products occupy a large market because of its long shelf life and easy to carry. The casing packaging of ham sausage is mostly plastic film, among which PVDC film is widely used. Compared with ordinary PE film, paper, aluminum foil and other packaging materials, the amount of composite packaging using PVDC is much reduced, so as to achieve the purpose of reducing packaging and waste sources. In the United States, PVDC products are non-toxic and safe plastic materials, which have been widely used in food packaging; In Germany, PVDC packaging materials have green marks; About 60% of the small packaged food, drugs, chemical products and electronic products circulating in the markets of Japan and South Korea are packaged with PVDC. With the popularity of this new packaging material, the output of PVDC resin in western countries has increased year by year, with an annual growth rate of 2% in the United States and nearly 10% in Japan. In view of the current situation that the level of food packaging in China is still relatively backward, experts pointed out that the promotion and use of PVDC materials can not only improve the grade of packaging products in China, but also reduce the losses caused by product packaging, so as to enhance market competitiveness and establish a new image of enterprises. It can be predicted that in the future food packaging, the full and reasonable use of PVDC materials will gradually become the mainstream of China's packaging industry, and the main failure mode will change from delamination to matrix damage and fiber fracture, and the food loss will be greatly reduced after the salt particles solidify and form in the printing process

any disposable consumption material, if its waste is not properly treated and a reasonable consumption and use system is not established, will cause environmental pollution. Europe is the region that has done the best in environmental protection, but plastic materials are still widely used for food packaging. China has not formed a reasonable waste treatment system, nor has it given support to the development and application of plastic waste treatment technology. It is unscientific and not serious to simply think that plastic materials are not as environmentally friendly as paper. In the evaluation of environmental materials, Europeans adopt the method of whole process evaluation. I don't think paper is more environmentally friendly than plastic. In terms of resources and energy consumption, plastic is more than 1/2 less than paper, and the consumption of materials is 1//5 less. In terms of the degree of water pollution caused by the processing process, 300 plastic bottles are equivalent to a paper can with the same capacity

people are always worried about plastic food packaging, and some even think that plastic is "toxic". This concern about plastic food packaging may come from people's misunderstanding, that is, to equate all plastics with PVC. Many people have known that soft PVC film is not suitable for food packaging because it contains volatile plasticizers, and has been eliminated at present. The sanitary properties of plastic PE, PP, pet, PS, etc. now used for food packaging are qualified. Moreover, in recent years, with the progress of analysis and identification technology, accurate identification of the components in plastics and the changes under various conditions shows that plastics used for food packaging are safe
