Degradable plastics refer to a class of plastics whose products can meet the performance requirements of use, have unchanged performance during the storage period, and can be degraded into environmentally harmless substances after use under natural environmental conditions.
Degradable plastics mainly include photodegradable plastics, disintegrating plastics and biodegradable plastics.
Photodegradable plastics and disintegrating plastics are processed from ordinary plastics as raw materials and cannot be completely decomposed; biodegradable plastics are extracted from biomass resources (such as plant fibers, starch, etc.) and can be completely decomposed.
The upstream raw materials of degradable plastics mainly include PLA, PHA, PGA, PBS, PBAT, PCL, etc.; the midstream products mainly include tableware, film, film paper, express bags, clothing, plastic tape, 3D printing materials, etc.; the downstream is mainly used in packaging, Agriculture, 3D printing, modern medicine, textile industry, etc.
As countries around the world pay more and more attention to the issue of plastic pollution, various forms of environmental protection requirements continue to be introduced, and the concept of "plastic restriction" gradually reaches a global consensus, the development trend of degradable plastics is getting stronger and better.
