Plastics can be classified according to their own properties

In the plastic packaging industry, large-scale enterprises, state-owned enterprises, private enterprises and scattered, the overall size of the industry is small, while facing the intrusion of many foreign brands in the market, such as the German SCHOTT Group's strong technical and economic strength Big move into the Chinese market. During the 12th Five-Year Plan period, China's plastic packaging industry needs to be integrated, and through the combination of corporate mergers, acquisitions, mergers and other means to form a number of large-scale enterprises, joint enterprises, thereby promoting the industry forward healthy development.

With the rapid development of China’s economy, the improvement of people’s living standards and the increase in medical expenses caused by the aging of the population, the development of new drugs, the acceleration of the reform of the medical security system and the expansion of medical insurance for urban residents, the plastics industry will continue to maintain Rapidly growing momentum. In addition, China's plastic packaging materials quality 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 accounts for less than 10%. The next few years will be the period of rapid development of China's plastic packaging industry.

The "12th Five-Year Plan" development plan for the plastic packaging industry (Consultation Draft) proposes that plastic packaging is an important part of the plastics industry. Containers of packaging materials that are in direct contact with pharmaceuticals constitute the basic elements of medicines, and they are essential to the quality and safety of medicines. Has an important influence. Therefore, in the “Twelfth Five-Year Plan” of the plastics industry, plastic packaging should be placed on the same position as pharmaceuticals, rather than supporting industries, and it should be clearly stated in the national plastics industry planning. The research of plastic packaging materials should be synchronized with the development of pharmaceuticals, and efforts should be made to increase the policy support for the plastic packaging industry, reflecting the industrial policies of plastic packaging materials, the key product areas and technology areas for development, and the direction of development.

Plastics can be classified according to their own properties: thermoplastics that can be repeatedly melt-molded and can maintain their properties, and thermosets that can be melt-molded only once. According to their use, they can be divided into general-purpose plastics with a wide range of usage, low price, and good overall performance, such as PE, PP, PVC, PS, and amine-based plastics, which have good physical-mechanical strength and may be used instead of metals in construction machinery. Engineering plastics such as: ABS, nylon, polyester, POM, TPX-1, etc. And in a certain type of performance has a particularly good class of engineering plastics, such as: a particularly good radiation resistance, high temperature resistance and other special plastics, such as: polyarylsulfone, liquid crystal polymers. According to the molecular size of thermoplastic resin molecules, thermoplastics can be divided into two types: amorphous polymers and crystalline polymers.
