Plastic is a synthetic or natural high polymer resin as the main materials. After adding various additives, has the ductility under certain temperature and pressure, cooling can be fixed after the shape of material. Natural or synthetic polymer molecules under the molten state, and the process of uniform distribution of additives molecules around plasticizing, has reached this process is called plasticizing, haven't reached, is considered not plasticizing. Plastic packaging is one of the four materials in the packaging industry, paper and paperboard (30%), plastic (25%), metal (25%), glass (15%).
Packaging industry developmentIn synthesis, 25% used in packaging industry, therefore an important sector in the plastic packaging, plastic packaging is one of the four materials in the packaging industry, paper and paperboard (30%), plastic (25%), metal (25%), glass (15%). The above two 25% fully illustrate the importance of the plastic packaging industry. Although plastic packaging industry is the second packaging materials, actually with surface than paper and cardboard packaging. But the plastic packaging industry according to the rate of 5% a year in development, and other packaging materials, including paper and cardboard, metal, glass, ceramic, ramie cotton growing at the rate of 2%, only for this one day plastic packaging manufacturers industry will become the first more than paper and paperboard packaging materials.
China's modern packaging industry developed rapidly since the reform and opening up policy. After 30 years of development, China packers has already become a paper, plastic, metal, glass, packaging and printing and packaging machinery equipment as the main industry of independent, complete, complete industrial system, and in the Yangtze River Delta, the Pearl River Delta, bohai bay for key areas of packaging industry pattern.
Tell from the amount of packaging industry, China is large, but not the packing power, performance for the enterprise independent innovation ability is still weak, low product added value, the value of flexible plastic packaging in the industry chain is not sufficient. Low level repeated construction, lead to overcapacity of low-end products and high-end product supply to the contradiction in the development of the lack of staying power. China's packaging industry need to rely on growth, expanding capacity of development, to rely on scientific and technological innovation, technological progress, optimize the structure of adjustment, strengthen the core competitiveness of the development of the industry.
