What is degradable packaging material?

Degradable plastics refer to plastics that are easily degraded in the natural environment by adding a certain amount of additives (such as starch, modified starch or other vitamins, photosensitizers, biodegradable agents, etc.). ) In the production process. Synthetic degradable packaging materials can be endowed with similar properties to traditional packaging materials, and the wide application of degradable packaging shows its great potential to replace existing packaging materials. Degradable packaging has a broad development prospect and has become a research hotspot all over the world. The performance characteristics, degradation mechanism, processing technology and application of various degradable packaging materials were reviewed.

According to the degradation mechanism, it can be divided into biodegradable plastics, photodegradable plastics, photodegradable plastics, photodegradable plastics and water-degradable plastics.
