The custom biodegradable packing bags does not cause environmental pollution, and not only realizes convenience, but also protects the environment. At present, custom biodegradable packing bags are not fully popularized, so some people may not understand it. This article introduces the main bio-based materials of custom biodegradable packing bags!
The meaning of custom biodegradable packing bags is that they can be degraded, but degradable bags can be divided into "degradable" and "total degradable". Custom biodegradable packing bags refer to plastic packaging bags that are easily degradable in the natural environment after adding a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradable agents, etc.) during the production process. in a decline in stability. Fully degradable packaging means that plastic packaging bags degrade into water and carbon dioxide. The main sources of this fully degradable material are corn, tapioca and other products that are processed into lactic acid, or PLA.

Polylactic acid (PLA) is a novel nanobiological and renewable biodegradable material. Starch is converted to glucose by saccharification, which is then converted to high-purity lactic acid by fermentation of glucose and certain strains. It has good biodegradability and can be completely degraded by natural microorganisms under specific conditions after use. Carbon dioxide and water will not pollute the environment, it is very beneficial to protect the environment, and it is an environmentally friendly material for workers.
Currently, PLA + PBAT is the main bio-based material for custom biodegradable packing bags. Under composting (60-70°C) conditions, it can be completely decomposed into water and carbon dioxide within 3-6 months without polluting the environment.
