Pollution-free degradation of plastic film in Shanghai

The pollution-free plastic film that can be self-degraded or pulverized without any artificial treatment has been successfully studied and certified by the Shanghai Institute of Organic Chemistry. The pollution-free degradation plastic film is made of polyethylene, and then added with photodegradation additives such as photooxidation degradation agent, oxidation degradation promoter, biodegradation agent, and degradation control agent. It is prepared by a unique process with low cost and is suitable for large-scale production. More than 10 tons of plastic film developed by researchers will be tested in more than 4,000 acres of vegetables, fruits and flowers in the suburbs of Shanghai. The plastic film covering all fields will achieve the same thermal insulation and high yield as ordinary plastic film. After 3 to 6 months, the mulch film left in the ground is self-degrading, cracked or completely powdered under sunlight, and the part of the mulch pressed in the ground can also be powdered without contaminating the soil. The use of such a plastic film can save the cost of manual processing of plastic film, and the technical performance of the international leader. Experts believe that it helps to protect the ecological environment and has good economic returns. It is worthwhile for rural areas to be widely used in rural areas.
