Degradable plastics refer to a kind of plastics whose products can meet the requirements of use, and their properties remain unchanged during storage, but can be decomposed into environmentally harmless substances under natural environmental conditions after use. So it is also called environmentally degradable plastic.

There are many new plastics: photodegradable plastics, biodegradable plastics, photooxidized-biodegradable plastics, carbon dioxide-based biodegradable plastics and thermoplastic starch resin degradable plastics.

brief introduction

The aging degradation of polymers is directly related to the stability of polymers. The aging and degradation of polymers will shorten the service life of plastics. Therefore, since the advent of plastics, scientists have devoted themselves to the study of anti-aging or stabilization to prepare high-stability polymer materials, and scientists from all over the world are also competing to develop environmentally degradable plastics by using the aging and degradation behavior of polymers.

The main application fields of degradable plastics are: agricultural plastic film, various plastic packaging bags, garbage bags, shopping bags in shopping malls and disposable tableware.
