Biodegradable plastic bags are constantly in use. Using biodegradable plastic bags can reduce environmental pollution, and there are many types of biodegradable plastic bags? Want to know more, just see below?

Biodegradable plastic bag manufacturers remind you that according to the definition of the national standard for biodegradable plastic shopping bags GB/T38082-2019, shopping bags made of biodegradable plastics used to carry goods in sales, services and other places are collectively referred to as biodegradable plastics Shopping Bag.
Biodegradable plastic shopping bags are divided into two categories: direct food contact and non-food direct contact. These two types of products should be clearly marked on the shopping bag as “biodegradable plastic shopping bag for direct food contact” or “biodegradable plastic shopping bag for non-food direct contact”, and the shopping bag’s implementation standards, specifications, and weight should also be marked. , Manufacturer, environmental protection and safety statement, etc.
The biodegradable plastic used in the manufacture of biodegradable plastic shopping bags refers to a type of plastic that can be degraded by microorganisms that exist in nature, such as bacteria, molds (fungi) and algae. The ideal biodegradable plastic has excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and finally becomes inorganicized to become a component of the carbon cycle in nature.
Biodegradable plastics can be completely degraded when buried in soil for 5 to 6 months under normal climatic conditions and will not affect plants. Compared with traditional plastic packaging materials, the cost of biodegradable materials is slightly higher, but they have the advantages of green environmental protection, energy saving and emission reduction, and renewable raw materials, which can solve the problem of “white pollution”, reduce oil consumption, and ease the pressure on petrochemical resources. Biodegradable plastic shopping bags will provide a sufficient alternative guarantee to curb “white pollution”.
Biodegradable plastic bags should have four elements:
1. The material can be decomposed by microorganisms and converted into carbon dioxide;
2. The material can be decomposed in the process of burial, and there is no “white pollution”;
3. Buried soil residues will not have a negative impact on the growth process of organisms;
4. Does not contain heavy metal residues.
