With the steady, sustainable and healthy development of the economy as a whole, China's plastic industry has achieved leapfrog development through the "Tenth Five Year Plan". The plastic products industry has made remarkable achievements and achieved significant double-digit growth in major economic indicators. Its gross output value ranks third in the light industry and fifth in exports. It has become a pillar industry in the healthy development of China's national economy This paper introduces the general situation of the development of plastic processing industry in 2006, expounds the guiding ideology, development goals and development trends of the plastic industry during the "11th Five Year Plan" period, discusses the major impact of the development trend of PE,PVC resin and additives industry on the plastic processing industry, and puts forward the key development trend of PE,PVC plastic products

Plastic processing is also called plastic molding processing. It is the general term of various processes for converting synthetic resin or plastic into plastic products, and it is a large production department in the plastic industry. Plastic processing generally includes plastic ingredients, molding, machining, jointing, decoration and assembly. The last four processes are carried out after the plastic has been molded into products or semi products, also known as plastic secondary processing.

Plastic products are the general name of living, industrial and other products processed with plastic as the main raw material. Including plastic injection molding, blistering and other products with all processes. Plastic is a kind of plastic synthetic polymer material. From January to August 2021, the output of plastic products in China will be 52.27 million tons, with a year-on-year growth of 11.4%

With the development of economy and the adjustment of rural industrial structure, various industries in China are showing increasing demand in stretch film malls. Shenzhen stretch film is used for the sale and transportation of various products. Its primary role is to stabilize, conceal and maintain products. It is necessary for Shenzhen stretch film to have high puncture resistance, outstanding shortening and certain shortening stress. During the shortening process, the film shall not have holes. Since the shortening film is often suitable for outdoor use, it is necessary to add UV anti ultraviolet agent.

The output value of Shenzhen stretch film accounts for about 20% of the total output value of plastic products, which is one of the types of plastic products with rapid increase in output value. From the perspective of the application field of Shenzhen stretch film (0.06 mm~0.26 mm thick), the packaging industry has the largest amount, the largest variety and the widest use, accounting for about 2/3 of the cost, followed by agriculture, accounting for about 30%, and functional films, such as microporous films, shielding films, geomembranes, etc.
