Plastic packaging materials mainly include plastic flexible packaging, woven bags, hollow containers, and turnover boxes, which are one of the largest areas in the application of plastic products. In 2005, the plastic packaging exceeded 7 million tons, accounting for about 1/3 of the total output of packaging materials, ranking first among various packaging materials. Various kinds of mineral products, chemical products, synthetic resins, raw salt, grain, sugar, cotton and wool have been widely used in plastic woven bags and heavy bags; beverages, detergents, cosmetics, chemical products, etc. have developed rapidly in China. , Indispensable composite films, packaging films, containers, turnover boxes and other plastic packaging materials have great needs. Food and medicine are important materials for the national economy and people's livelihood, and the corresponding packaging demand is very strong. The growth rate of pharmaceutical packaging in China ranks first in the world's top eight drug-producing countries.
In the 21st century, China's accession to the WTO and global economic development will further promote the development of China's domestic demand and foreign trade, and will drive BOPP (biaxially oriented polypropylene film) and plastic flexible packaging products into the high-growth period for a new round of market demand. According to industry estimates, China's BOPP film market reached 1 million tons in 2005, with an average annual growth of more than 20%. The development of the flexible packaging industry has provided a good market opportunity for the development of the BOPP industry.
