1 Domestic development According to the '2013-2017 China Plastic Packaging Industry Market Outlook and Investment Opportunity Analysis Report' statistics show that in 2011, the total industrial output value of the packaging industry was 929.639 billion yuan, and the total industrial output value of the plastic packaging industry accounted for the national packaging industry. Calculated by 10% of the total industrial output value, the total industrial output value of the plastic packaging industry in 2011 is estimated to reach 90 billion yuan, with the number of enterprises reaching 2,000. my country's plastic packaging industry can produce more than 30 types of plastic packaging materials in six categories, which can basically meet the needs of the domestic pharmaceutical industry, and its annual sales have accounted for about 15% of the total sales of the plastics industry. In the plastic packaging industry, there are few large-scale enterprises and state-owned enterprises, and many private enterprises are scattered. The overall scale of the industry is small. At the same time, it faces the market invasion of many foreign brands. During the Twelfth Five-Year Plan period, my country's plastic packaging industry needs to be integrated, through various means such as enterprise alliances, acquisitions, mergers, etc., to form some large-scale enterprises and joint enterprises, so as to promote the healthy development of the industry forward. 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 has increased, the pace of reform of the medical security system has accelerated, and the expansion of urban residents’ medical insurance, the plastics industry will continue to maintain The momentum of rapid growth. In addition, the quality of China's plastic packaging materials and packaging varieties are significantly lower than international standards. In developed countries, plastic packaging accounts for 30% of the value of plastic products, compared to less than 10% in China. The next few years will be a period of rapid development of China's plastic packaging industry. The 'Outline of the Twelfth Five-Year Development Plan for the Plastic Packaging Industry (Draft for Comment)' puts forward that plastic packaging is an important part of the plastics industry. Have an important impact. Therefore, in the 'Twelfth Five-Year Plan' of the plastics industry, plastic packaging should be placed in the same position as medicines, rather than supporting industries. It should be clearly defined in the national plastics industry plan. The research of plastic packaging materials should be synchronized with the development of medicines, and policy support for the plastic packaging industry should be increased to reflect the industrial policy of plastic packaging materials, key development product areas and technical fields, and development directions. 2 Basic Information Plastic Classification According to its own properties, plastics can be divided into two categories: thermoplastics that can be melt-molded repeatedly and can basically maintain their characteristics and thermosets that can only be melt-molded once. According to its use, it can be divided into general plastics with a wide range of applications, low prices, and good overall performance, such as PE, PP, PVC, PS, and amino-based plastics with good physical and mechanical strength, and may be used in engineering machinery instead of metals. Engineering plastics such as: ABS, nylon, polyester, POM, TPX-1, etc. And a class of engineering plastics with particularly good properties, such as special plastics with particularly good radiation resistance and high temperature resistance, such as: polyarylsulfone, liquid crystal polymer, etc. According to the molecular crystal size of thermoplastic resins, thermoplastics can be divided into amorphous polymers and crystalline polymers. Main characteristics The main characteristics of plastics are: First, the density is low, the specific strength is high, and a higher packaging yield can be obtained, that is, 'the packaging volume or packaging area per unit mass. Second, the chemical resistance of most plastics is good. , It has good acid resistance, alkali resistance, resistance to various organic solvents, long-term storage, without oxidation. Third, it is easy to shape, and the required molding energy consumption is lower than that of metal materials such as steel. Fourth, it has good transparency and easy Coloring. Fifth, it has good strength, high strength per unit weight, impact resistance, and easy modification. Sixth, low processing cost. Seventh, excellent insulation. The packaging industry is developed in the synthesis, and 25% is used In the packaging industry, which is an important sector in the plastic packaging industry, plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, plastics account for 25%, metals account for 25%, and glass account for 15%. The two 25% fully illustrate the importance of the plastic packaging industry. Although the plastic packaging industry is the second packaging material, its practicality is not as good as paper and cardboard packaging. However, the plastic packaging industry is developing at a rate of 5% every year. Other packaging materials, including paper and cardboard, metal, glass, ceramics, hemp and cotton, etc. are only growing at a rate of 2%. Therefore, one day the plastic packaging industry will surpass paper and cardboard and become the first packaging material. China The modern packaging industry has developed rapidly since the implementation of the reform and opening up policy. After 30 years of development, China’s packaging industry has become an independent, complete, integrated, A complete industrial system and a packaging industry pattern with the Yangtze River Delta, the Pearl River Delta, and the Bohai Bay as the key areas. In terms of the total packaging industry, China is already a major packaging country, but not a packaging power. It shows that the independent innovation ability of enterprises is still The value of packaging is weak, the added value of products is low, and the value of packaging is not yet fully reflected in the industry chain. Low-level repeated construction has led to a prominent contradiction between overcapacity of low-end products and insufficient supply of high-end products, and lack of stamina for development. China’s packaging industry needs to change from simplicity Relying on volume growth, expanding production capacity development, and turning to relying on technological innovation, technological progress, and structural optimization and adjustment, enhance the core competitiveness of industrial development.
