What are the types of biodegradable plastic bags

Biodegradable plastic bags are produced using environmentally friendly PBAT+PLA (polybutylene adipate terephthalate+polyru acid), and degrading agents and other raw materials are added. Biodegradable plastic bags are human-friendly and environment-friendly packaging made of plant straws. Unlike the three major synthetic plastic packaging, biodegradable packaging bags can be automatically degraded when the biological environment meets certain requirements after being discarded. , No harm to people or the environment, it belongs to green packaging.

The raw materials of biodegradable plastic bags are mainly PBAT+PLA (polybutylene adipate terephthalate+polyru acid), or packaging bags made of starch and other biodegradants, also called fully biodegradable plastic bags . This kind of biodegradable packaging bag is mainly degraded by the action of microorganisms. Fully biodegradable packaging bag, compostable, fully degradable in 180 days, environmentally friendly and harmless.

Another type of biodegradable plastic bag is a packaging bag made of polyethylene plastic as the main component, mixed with mineral powders such as photodegradants and calcium carbonate, also called photodegradable packaging bags. This kind of photodegradable packaging bag is degraded under the action of sunlight. Photodegradable materials are divided into synthetic photodegradable materials and additive photodegradable materials. Photodegradable packaging bags refer to a process in which polymer chains are degraded in an orderly manner under the influence of ultraviolet rays.
