In our daily life, the use of degradable plastics is often called for, but we may have less awareness of degradable plastics literally. Degradable plastic refers to a class of products that can meet the performance requirements of users, and its performance will not change during storage, and can be degraded into environmentally harmless substances after use under certain natural environmental conditions, so as to achieve the purpose of environmental protection.
Degradable plastics can be divided into the following categories: photodegradable plastics, disintegrating plastics and biodegradable plastics.
Among them, photodegradable plastics and disintegrating plastics are made of ordinary plastics as processing raw materials and cannot be completely degraded; Biodegradable plastics are extracted from biomass resources such as plant fibers and starch and can be fully 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 products are involved in all aspects of work and life; Downstream is mainly used in packaging, agriculture, 3D printing, modern medicine, textile industry, etc., the application field is very wide.
As countries around the world pay more and more attention to the problem of plastic pollution, and continue to introduce various forms of environmental protection requirements, coupled with the concept of "plastic limit" gradually formed a consensus on a global scale, degradable plastics have been pushed to the tuyere of a era, it can be seen that the concept of degradable plastics will usher in a huge investment opportunity, is not to be missed concept investment.
