A biodegradable plastic bag is a bag made of biodegradable plastic. Biodegradable plastic refers to a type of plastic that degrades under the action of microorganisms and algae existing in nature. An ideal biodegradable plastic is a polymer material with excellent performance in use. After disposal, it can be decomposed by environmental microorganisms and thus become part of the carbon cycle in nature.

Biodegradable plastic bags are plastic bags that can melt quickly when exposed to sunlight and moisture. Inspected by the Environmental Protection Product Quality Supervision and Inspection Center, all indicators of biodegradable plastic bags meet or exceed the specified quality standards. They are hygienic, pollution-free and other characteristics, and are one of the most advanced environmentally friendly products currently available.

 

Biodegradable plastic bags can be incinerated, with residues being inorganic powder that does not produce oil gel or toxic gases. When buried in soil or not exposed to light, they can still degrade through thermo-oxidative action. Biodegradable plastic bags can degrade under the action of ultraviolet rays, with most residues being inorganic powder.

 

Biodegradable plastic bags are produced using environmentally friendly PBAT + PLA (polybutylene adipate terephthalate + polylactic acid) as the main raw materials, supplemented with degradants and other ingredients. Different from the three major synthetic plastics, biodegradable plastic bags are made from plant straw and other materials that are friendly to humans and the environment. After disposal, they can decompose automatically under suitable biological environmental conditions. They do not cause harm to humans or the environment and belong to green packaging.

 

The main raw material of biodegradable plastic bags is PBAT + PLA (polybutylene adipate terephthalate + polylactic acid), mixed with starch and other biodegradants. Such plastic bags are also called biodegradable plastic bags, which are mainly decomposed by microbial action. Another type of biodegradable plastic bag is based on polyethylene plastic, mixed with photo-degradants and mineral powders such as calcium carbonate. It is also called a photo-degradable plastic bag, which decomposes under the action of sunlight.
