Plastic packaging in the synthesis, 25% for the packaging industry, for this important part of the plastic packaging industry, plastic packaging is one of the four major packaging materials: paper and paperboard accounted for 30%, 25% of plastic, metal Accounting for 25%, accounting for 15% of the glass. The above two 25% fully illustrates the importance of plastic packaging industry. Although the plastic packaging industry is the second packaging material, its surface is not as good as paper and cardboard packaging. But the plastic packaging industry at an annual rate of 5% in the development, and other packaging materials, including paper and cardboard, metal, glass, pottery, cotton only 2% of the rate of growth, for which the plastic packaging industry Will be more than paper and cardboard and become the first packaging material. China's modern packaging industry since the implementation of reform and opening up policy to be developed rapidly. After 30 years of development, China's packaging industry has become a paper, plastic, metal, glass, packaging, printing and packaging machinery and equipment as the main industry of independent, complete, wide range of industrial system and the Yangtze River Delta, Pearl River Delta, Bohai Bay as the key areas of the packaging industry pattern. From the total packaging industry, China is a packaging power, but not a packaging power, the performance of independent innovation capability is still weak, low value-added products, the value of packaging in the industry chain is not yet fully reflected. Low-level redundant construction, resulting in low-end product overcapacity and lack of high-end products, the contradiction between the lack of development potential. China's packaging industry needs to rely solely on the growth of capacity, expand production capacity development, to rely on scientific and technological innovation, technological progress, optimize the adjustment structure, and enhance the core competitiveness of industrial development. In the packaging containers, the original packaging of beverage containers are glass bottles followed by paper composite cans, and then PET bottles, PET bottles are now rigid and carbonated beverages are non-carbonated drinks, the largest packaging materials in the United States in 1991 accounted for 26.5% of beverage packaging containers, glass bottles from 1981 to 28.9% down to 19.5%, aluminum cans accounted for 39%. And plastic bottles are more than 3% annual growth rate of rapid growth. Suzhou blow molding processing can certainly say that even in the plastic packaging industry has been blamed most countries. Plastics will continue to grow at a much faster rate than other packaging materials, since many of the properties of plastics are irreplaceable in any other packaging material. Plastic packaging industry has been in the occupation of the field of packaging sales, has been the development of transport packaging, and ultimately will force the metal is still the main "transport packaging" to replace the plastic-based.
