What are biodegradable packaging materials?
Synthetic biodegradable packaging materials can be endowed with similar properties as traditional packaging materials, and the wide application of biodegradable packaging indicates its great potential to replace the current packaging materials.
Biodegradable plastics is added in the production process of additives (such as starch, modified starch or other vitamins, photosensitizer, biological degradation agent), decreases its stability in the natural environment, easily degradable plastics.
Biodegradable packaging has a bright future and has attracted worldwide attention. In this paper, the properties, degradation mechanism, processing technology and application of various kinds of degradable packaging materials are reviewed. According to the mechanism of degradation, it can be divided into biodegradable plastics, biodegradable plastics, light / biological double degradable plastics and water degradation plastics.
