Development of the plastic packaging industry

25% of the synthetic resins are used in the packaging industry. For this reason, the plastic packaging industry is an important sector in the packaging industry. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, and plastic accounts for 25%. 20% of metal and 15% of glass. The above two 25% fully illustrate the importance of the plastic packaging industry. Although the plastic packaging industry is now the second packaging material, its application is not as good as the packaging of paper and cardboard, but the plastic packaging industry is developing at a rate of 5% every year, and other packaging materials, including paper and cardboard, metal, glass, Ceramic linen and other cotton products are only growing at a rate of 2 ‰. To this end, the plastic packaging industry will one day surpass paper and cardboard and become the first packaging material. The amount of steam in Tianfang's back. The NUS Dangqiu plastic packaging industry has been developing with the continuous development of plastic raw and auxiliary materials, continuous advancement of molding technology and automation. Not only are they different in variety and form, but they have been able to meet high barrier and resistance in terms of performance. Packaging materials of various sterilization conditions appeared. Previous high-temperature cooking bags were only developed by the US Naval Institute for astronaut food packaging (expensive). Since the Japanese successfully developed this convenient and energy-saving plastic packaging material, it has grown at a high speed of more than 25% each year. Not only is it used for personal consumption of 1kg per bag, but it also has developed so-called large-scale products for business use that exceed 2kg per bag. High-temperature cooking bags, the shape of the bag has also developed from ordinary three-side sealed composite bags to stand-up bags, tetrahedron bags and other types. According to statistics, the structure of high-temperature cooking bags has developed from the original two-layer, three-layer, etc. More than 100 different materials and different levels of structure, packed nearly 1,000 kinds of various foods and dishes. It not only meets the needs of the Japanese people, but also exports from Japan to some countries with similar Japanese eating habits. In 1990, there were 40 manufacturers specializing in the production of high-temperature cooking bags in Japan, and in 1995 they had grown to 53. Statistics in 1990: about 50% of curry food and about 25% of aquatic products and soup food use high-temperature cooking bags
            In terms of packaging containers, the original packaging for beverages was glass bottles, followed by paper composite cans, and then PET bottles. Now rigid PET bottles are already the largest packaging material for carbonated and non-carbonated beverages. In the United States in 1991, they accounted for 26: 5% of beverage packaging containers, and glass bottles have fallen from 28,9% in 1981 to 19.5%. Aluminum cans account for 39%. And plastic bottles are growing rapidly at an annual growth rate of more than 3%. It can be said with certainty that even in countries where the plastic packaging industry is most blamed, such as Italy, plastics will continue to develop at a much faster rate than other packaging materials, because many of the characteristics of plastics are any other A packaging material cannot be replaced. The plastic packaging industry has already developed into transportation packaging while occupying the field of sales packaging. In the end, it will definitely force the current metal-based transportation packaging to be replaced by plastic.
