In the plastic packaging industry, large enterprises, state-owned enterprises less private enterprises and more scattered, the overall size of the industry is too small, while facing many foreign brands of market penetration, such as Germany's SCHOTT Group with its strong technical and economic strength of large-scale entry Chinese market. During the 12th Five-Year Plan period, China's plastic packaging industry needs to be integrated, through the combination of enterprises, acquisitions, mergers and other means to form a number of large enterprises, joint enterprises, thus promoting the healthy development of the industry forward. With the rapid development of China's economy, the improvement of people's living standard and the increase of medical expenses caused by population aging, the development of new drugs, the reform of medical security system and the expansion of urban residents' medical insurance, Kunshan Blow Molding Co., Will continue to maintain the momentum of rapid growth. In addition the quality of Chinese plastic packaging materials and packaging varieties are significantly lower than the international level. In developed countries, plastic packaging accounts for 30% of the value of plastic products, while China is less than 10%. The next few years will be China's rapid development of plastic packaging industry period. "Plastic packaging industry" Twelfth Five-Year "Development Plan (draft)" proposed plastic packaging is an important part of the plastic industry, direct contact with the drug packaging containers constitute the basic elements of drugs, drug quality and drug safety Have a significant impact. Therefore, in the plastics industry, "12th Five-Year Plan", the plastic packaging should be placed on the same position with the drug, rather than supporting the industry in the national planning of the plastics industry should be given clear. Plastic packaging materials research should be synchronized with the development of drugs, should increase the plastic packaging industry policy support, reflecting the industrial policy of plastic packaging materials, focusing on the development of product areas and technology, development direction. Plastic according to its own performance points can be divided into: can be repeated several times to melt the basic processing to maintain its characteristics and can only be carried out once the melting of thermosetting plastic molding two categories. According to their use can be divided into the use of a wide range of cheap, good overall performance of the general plastics, such as PE, PP, PVC, PS, and amine plastic has good physical and mechanical strength, may replace the metal used in construction machinery Of the engineering plastics such as: ABS, nylon, polyester, POM, TPX-1, and so on. As well as in a particular performance with a particularly good class of engineering plastics, such as: has a particularly good radiation resistance, high temperature and other special plastics, such as: poly-sulfone, liquid crystal polymers. According to the molecular size of thermoplastic resin molecular points, can be divided into amorphous thermoplastic polymer and crystalline polymer two categories.
