Development of packaging bag industry

　　In synthesis, 25% is used in the packaging industry, which is an important department in the plastic packaging industry. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, plastic 25%, metal 25%, and glass 15%. The above two 25% fully illustrate the importance of the plastic packaging industry. Although plastic packaging industry is the second largest packaging material, it is not as good as paper and cardboard packaging. However, the plastic packaging industry is growing at a rate of 5% every year, while other packaging materials, including paper and cardboard, metal, glass, ceramics, hemp and cotton, are growing at a rate of only 2%. Therefore, one day the plastic packaging industry will surpass paper and cardboard and become the first packaging material.

　　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 a packaging industry pattern with the Yangtze River Delta, the Pearl River Delta and the Bohai Bay as the key regions.

　　In terms of the total volume of the packaging industry, China is already a big packaging country, but not a strong packaging country. This is reflected in the fact 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 repeated construction has led to the contradiction between overcapacity of low-end products and insufficient supply of high-end products, and development lacks stamina. China's packaging industry needs to shift from relying solely on the growth of quantity and expansion of production capacity to relying on scientific and technological innovation, technological progress, and structural optimization to enhance the core competitiveness of industrial development
