The development trend of food packaging industry

traditional packaging forms have increased steadily

traditional packaging forms Tetra Pak, Tetra Pak pillow, fresh house and Baili bag, etc., and the use of these packaging continues to increase steadily. HDPE bottle (barrel) packaging is gradually recognized by consumers. Shrink film or adhesive label is used on the outside of the bottle, which increases the amount of adhesive and shrink film in dairy packaging, and new environmentally friendly packaging materials ops and pet also begin to enter the market. Glass bottle packaging still exists, but will gradually be replaced by paper cup packaging

with the strengthening of people's awareness of environmental protection, aclin has been applied in fresh milk and yogurt. At present, the development of this packaging is not clear, and the consumption increase this year will eventually make the smooth acceptance of this batch of products not too large. Baili bag is no longer a three-layer coextrusion film. Enterprises have worked hard to improve the product shelf life and prevent odor. Five layer coextrusion, aluminizing film, PVDC coating and other processes have been used in the production of Baili bag. At present, there are more than ten kinds of yogurt packaging forms, including fresh house, fresh cup, HDPE bottle (barrel), etc. plastic cup is still the mainstream packaging of yogurt packaging this year, and the cluster packaging made of carton and plastic film will continue to be popular. The PVC shrink film of the cup holder will be replaced by POF. The common milk powder packaging in the market this year is still mainly tin cans and PE composite bags. Although the membrane structure of composite bags has changed a lot, the most basic packaging form has not changed much. This year, various brands of lactic acid bacteria beverages have been fully launched in the market, and new packaging forms have emerged, including Tetra Pak pillows, secondary sterilization bottles, bang bang acid, Tetra Pak crown, plastic cups (including PS cups, PP cups), Baili bags and other forms. In the market this year, we will see the use of cartons with new processing forms (flexible pre printing) in the dairy industry, with lower cost and convenient revision

convenient flexible packaging will be favored.

metal packaging products are mainly aluminum two-piece cans, tinplate three piece beverage cans, food cans, etc. compared with flexible packaging, the technology is relatively mature. China's metal packaging has reached the level of similar products in advanced countries, and there are about 25 production lines for two-piece cans; There are nearly 300 production lines of tinplate three piece can manufacturing equipment. Its products supply about 4billion in the beverage industry and about 3.8 billion in the food canning industry every year. There are about 200 production lines of crown caps in the country. There are more than 500 production lines of iron printing equipment and iron coating equipment in the country, and more than 300 sets of imported equipment for various bottle caps. For metal packaging manufacturers, once the cost of metal packaging is reduced and the problem of difficult opening is solved, it will bring a leap in metal packaging

according to the statistical data of the National Bureau of statistics on the glass container industry, the output of the glass packaging industry is basically in a low-speed growth state this year, mainly due to insufficient effective demand and the supply structure does not adapt to the changes in market demand. Changes in energy prices directly affect the overall economic benefits of the industry. Although glass bottles can be recycled and reused, which is conducive to resource conservation and environmental protection, the problem cannot be solved and will restrict their own development

convenient flexible packaging products are favored by consumers, but how to reduce packaging costs and realize localized procurement of packaging products will be a difficult problem for flexible packaging products

the food packaging industry has developed rapidly. The mainstream packaging materials in the market are plastic packaging, paper product packaging and metal can packaging. Common plastic beverage packaging materials include polyethylene PE, polyvinyl chloride PVC, polypropylene PP, polyethylene terephthalate (PET), polyvinylidene chloride PVDC, etc. Plastic packaging is the fastest growing demand in the packaging industry. Such materials include high impermeability, multi-functional freshness preservation, selective permeability, heat resistance, sterility (antibacterial), rust prevention, deodorization, resealable, easy to open and other characteristics, among which high impermeability multi-functional freshness preservation, sterile packaging materials, nanocomposite packaging materials and so on are developing most rapidly. With the improvement of the quality and functionality of plastic packaging products, new varieties of packaging plastics have been developed

due to the excellent characteristics of pen, the performance of pen bottle blown with pen is better than that of PET bottle. PVDC is a kind of packaging material with better comprehensive barrier performance in plastic packaging in the world. PZA polymer is a highly transparent material with good operating performance and resistance to water dissolution

the packaging materials of paper products are Tetra Pak and Kangmei bag, with shapes of roof bag, sterile square brick, etc. The disadvantage of paper packaging materials is that their pressure resistance and sealing accuracy are not as good as those of glass bottles and metal cans, and they cannot be heated and sterilized. Preformed cartons will reduce the heat sealing performance due to polyethylene oxidation, or lose elasticity and become uneven due to creases or lower than fiber hardening, causing difficulties to the filling machine

new technologies in the food packaging industry emerge in endlessly

people hope that packaging can reflect the characteristics of products, especially organic food. Just as food is good for health, packaging must be environmentally friendly. Sustainable packaging is gradually emerging and has potential. The potential of sustainable packaging is great for products that combine content and packaging. Sustainable packaging will develop rapidly, and oil prices provide opportunities for sustainable packaging. Sterile plastic packaging will replace hot filled PET bottles, which is lighter and cheaper. Low acid beverages will be aseptically filled with PET bottles. However, pet is still widely favored by consumers and food and beverage manufacturers. HDPE multi-layer barrier containers are usually used in the market, and PET bottles are more transparent than them. The future trend of low acid products is aseptic filling of plastic bottles. Aseptic hot filling has its own advantages, but the bottle technically needs to break through the bottle wall without vacuum edge. High pressure processing has some deficiencies in the cost and production cycle of stamping fasteners into 175 steel plate, but its advantages are very obvious. The role of packaging is crucial. Food is usually packaged first, and then enter the processing link with the packaging. The selection of packaging materials is very important to processing technology. It must be ensured that the high pressure will not damage the structure of the packaging bag or any material of the packaging material will penetrate into the product. It is very common for red meat products to be packaged with vanadium products supplied in this way, accounting for nearly 90% of the total output. It is unlikely that fresh fish meat will be packaged with modified atmosphere packaging. However, the packaging of fresh fish using modified atmosphere packaging will gradually rise, on the premise of technology. Customized for customers, the only way to meet the special requirements of customers. Packaging equipment must be highly flexible. This packaging form is very popular now. Nanotechnology will also be increasingly used in food packaging
