Why are Biodegradable Bags Degradable?

Mar. 07, 2020

Biodegradable Bag is the use of microorganisms to decompose packaging bags. There are two main reasons for natural decomposition by microorganisms. One is the use of biodegradable materials in the production of biodegradable bags. The packaging bag can be decomposed directly by microorganisms when not in use at the later stage. The second is the natural decomposition of the packaging bag. All packaging bags will decompose under natural conditions, but the rate of decomposition is fast or slow, while the rate of biodegradable bags Relative to natural degradation rate may be faster, more than twice the natural degradation rate.

Biodegradable Bag

Biodegradable bags are packaging bags made of biodegradable plastic. Biodegradable plastic refers to a type of plastic that is degraded by the action of microorganisms and algae existing in nature. The ideal biodegradable plastic is a kind of high-molecular material that has excellent performance and can be decomposed by environmental microorganisms after being discarded, and then transformed into a component of the carbon cycle in nature.

A biodegradable bag is a plastic bag that can dissolve quickly when exposed to sunlight. After inspection by the Environmental Product Quality Supervision and Inspection Center, all the indicators of the biodegradable bag have reached or exceeded the prescribed quality standards. They are hygienic and pollution-free, and are one of the most advanced environmentally-friendly products.

The biodegradable bag can be incinerated, and the residue is inorganic powder, which does not produce oil glue and toxic gas. In the case of soil burial or no contact with light sources, degradation can still occur through the action of thermal oxygen. The biodegradable bag can be degraded under the action of ultraviolet rays, and most of the remaining residue is inorganic powder.

The biodegradable bag is produced by using environmentally friendly PBAT + PLA (polybutylene terephthalate + polylactic acid), and adding degrading agents and other raw materials. Biodegradable bags are human and environment-friendly items made from plant straws. Unlike the three major synthetic plastics, after being discarded, biodegradable bags can be automatically decomposed under conditions that the biological environment meets certain requirements. It will not cause harm to people and the environment. It belongs to green packaging.

The plastic bag added with the degradable masterbatch during the production of the plastic bag is called a biodegradable bag. The biodegradable bag can be automatically decomposed under certain conditions after 90 days. The biodegradable bag is made of degradable biodegradable materials. The material contains PLA + PBAT. The use function is no different from ordinary plastic bags, but it has more functions. Because PLA has antibacterial and antifungal properties, so does the biodegradable shopping bag. The biodegradable bag has the characteristics of sanitation, harmlessness and pollution-free, etc., and is one of the advanced environmental protection products at present. This degradable plastic bag is produced by using harmless polyolefin resin and adding raw materials such as degradation agents. The introduction of biodegradable bags has brought hope for reducing the pollution of white Garbage Bag.

The biodegradable bag can be decomposed into carbon dioxide and water in 180 days under natural soil or industrial composting conditions. Biodegradable material is an environmentally friendly product prepared from polyester biodegradable raw materials through a special process. It has the characteristics of harmless, bacteriostatic, mildew-resistant, non-irritating and compostable. Health and environmental protection features.

The above is the reason why the biodegradable bag introduced can be degraded by Biodegradable Bag Manufacturer.
