What is degradable plastic?

Degradable Plastics Committee: Degradable plastics is a big concept, which is the loss of certain properties (such as integrity, integrity, molecular mass, structural or mechanical strength) and/or plastics that have broken down. Among them, photodegradable plastics and thermo-oxidatively degradable plastics are broken plastics and should not be attributed to biodegradable plastics. Degradable plastics should be tested using standard test methods that reflect changes in properties, and should be classified according to the manner of degradation and life cycle. Without combining the types of degradable plastics and their degradation environmental conditions, and generally speaking of degradable plastics, it does not mean that such plastics can be completely degraded into substances that are harmless to the environment.
