Over the past 30 years of reform and opening up, China has made great economic achievements, but the environmental pollution and ecological damage caused by development have become increasingly severe and prominent. The environmental problems China faces are more severe than any other country, such as Japan, the United States, and other developed countries in Europe and the United States have paid more and more attention to environmental protection, and the opening of new energy technology has given attention and support, which has achieved the upgrading and development of industrial structure. As the world’s factory, China is still experiencing high energy consumption. In the industrial production stage of emissions, industrial pollution has become the culprit of Chinese-style pollution, and the high-carbon lifestyle of Chinese people is the Achilles heel of Chinese-style pollution. It can be seen that the environmental problems facing China are a social issue. PVC heat shrinkable film material is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder. According to different purposes, different additives can be added, and PVC plastics can present different physical and mechanical properties. Adding an appropriate amount of plasticizer to the polyvinyl chloride resin can make a variety of hard, soft and transparent products. PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for floors, ceilings and leather surfaces. Polyvinyl chloride hard boards are widely used in the chemical industry to make various storage tank linings, corrugated boards of buildings, door and window structures, wall decorations and other construction materials.
