1 domestic development

According to the plastic packaging industry in China market in 2013-2017 of foresight and investment opportunity analysis report, statistics show that in 2011, packaging industry gross industrial output value is 929.639 billion yuan, with plastic packaging industry of gross industrial output value in the packaging industry of the country's industrial output 10% computation, plastic packaging industry in 2011 gross industrial output value estimated at 90 billion yuan, the number to 2000. China's plastic packaging industry can produce six categories of more than 30 varieties of plastic packaging materials, has been able to meet the basic needs of the domestic pharmaceutical industry, the annual sales of the plastic industry accounts for about 15% of the total sales.
In the plastic packaging industry, large enterprises, state-owned enterprises are few, private enterprises more and scattered, the overall scale of the industry is small, while facing many foreign brands market invasion, such as Germany short group with its strong technical and economic strength to enter the Chinese market on a large scale. During the 12th five-year plan period, China's plastic packaging industry needs to be integrated, through joint enterprises, acquisitions, mergers and other means, the formation of some large enterprises, joint enterprises, so as to promote the healthy development of the industry.
With the rapid development of China's economy, the increase of medical expenses caused by the improvement of people's living standard and aging population, the increase of new drug development, the acceleration of the reform of medical security system and the expansion of medical insurance for urban residents, the plastics industry will continue to maintain the momentum of rapid growth. In addition, China's plastic packaging material 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, compared with less than 10% in China. The next few years will be a period of rapid development of China's plastic packaging industry.
According to the outline of the 12th five-year plan for the development of the plastic packaging industry (draft for soliciting opinions), plastic packaging is an important part of the plastic industry, and the packaging material containers that directly contact drugs are the basic elements of drugs, which have an important impact on drug quality and drug safety. Therefore, in the "twelfth five-year" plan of the plastic industry, the plastic packaging should be placed on the same status as drugs, rather than supporting industries, and should be clearly defined in the national plan of the plastic industry. The research of plastic packaging materials should be synchronized with the development of drugs, and the policy support for the plastic packaging industry should be strengthened to reflect the industrial policy of plastic packaging materials, key product areas and technical fields, and development direction.
2 basic information
Plastic classification
Plastic according to its own performance can be divided into: can be repeated many times melting molding processing and basic can maintain its characteristics of thermoplastics and thermosetting plastic can only be a melting molding two categories. According to its use can be divided into the use of a wide range of cheap, comprehensive performance of general plastic, such as PE,PP,PVC,PS, and amine plastic has good physical and mechanical strength, may replace metal used in construction machinery engineering plastics such as: ABS, nylon, polyester,POM,TPX-1. And in a performance has a particularly good class of engineering plastics, such as: has a particularly good radiation resistance, high temperature resistance and other special plastics, such as: polyaryl sulfone, liquid crystal polymer, etc.. Thermoplastics can be classified into amorphous polymers and crystalline polymers according to the molecular crystallization size of thermoplastics.
The main features
The main characteristic of plastic is: the first, density is small, compare strength tall, can obtain higher pack yield, namely "the package volume of unit mass or package area size. Second, most of the plastic chemical resistance is good, good acid resistance, alkali resistance, resistance to all kinds of organic solvents, long-term placement, no oxidation. Third, the molding is easy, the required molding energy consumption is lower than steel and other metal materials. Fourth, with good transparency, easy to color. Fifth, it has good strength, high strength per unit weight, impact resistance and easy modification. Sixth, low processing costs. Seventh, excellent insulation.
Development of packaging industry
In synthesis, 25% is used in the packaging industry, which is an important sector of the plastic packaging industry, plastic packaging is one of the four materials in the packaging industry: paper and cardboard accounts for 30%, plastic accounts for 25%, metal accounts for 25%, glass accounts for 15%. The above two 25% fully illustrate the importance of the plastic packaging industry. Although plastic packaging industry is the second packaging materials, in fact, with the surface is not as good as 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 砙, ramie cotton growing at the rate of 2%, only for this one day plastic packaging industry will become the first more than paper and paperboard packaging materials.
China's modern packaging industry has developed rapidly since the implementation of the reform and opening policy. After 30 years of development, China's packaging industry has become an independent, complete and complete industrial system with paper, plastic, metal, glass, packaging printing and packaging machinery and equipment as the main industries, and the packaging industry pattern with the Yangtze river delta, pearl river delta and bohai bay as the key areas.
In terms of the total amount of packaging industry, China has become a big country in packaging industry, but not a powerful country in packaging industry. This shows that the independent innovation ability of enterprises is still weak, the added value of products is low, and the value of packaging is not fully reflected in the industrial chain. Low-level and redundant construction has led to the acute contradiction between the excess production capacity of low-end products and the insufficient supply of high-end products and the lack of staying power for development. China's packaging industry needs to shift from relying solely on volume growth and expanding production capacity for development to relying on scientific and technological innovation, technological progress and optimization and adjustment of structure to enhance the core competitiveness of industrial development.

Packaging container
In terms of packaging containers, the former containers for beverage packaging were glass bottles, followed by paper composite cans, and then PET bottles. However, now rigid PET bottles have become the largest packaging material for carbonated drinks and non-carbonated drinks. In 1991, glass bottles accounted for 26.5% of beverage packaging containers in the United States. And plastic bottles are growing at an annual rate of more than 3%. To be sure, even in the countries where the plastic packaging industry is most culpable. Plastics will continue to develop at a much faster rate than other packaging materials because there are many characteristics of plastics that cannot be replaced by any other packaging materials. Plastic packaging industry has occupied the field of sales packaging at the same time, has been to transport packaging development, will eventually force still based on metal "transport packaging", to replace the plastic.
