Biodegradable plastic bags, according to the standard of plastic bags under certain conditions, such as the temperature of 70 degrees, sufficient CO2 environment can be biodegradable. Therefore, there are two materials: 1.100% biodegradable modified poly (lactide) resin (PLA) 2.100% biodegradable thermoplastic starch/PBAT when biodegradable plastic bags enter the ocean and other non-standard environment will reduce the biodegradable performance of plastic bags. Therefore, choose the right biodegradable plastic bags, but also in the appropriate environmental requirements after the use of the bag for processing. Degradable plastic bags can be completely degradable, degradable plastic is made of plants straw and other friendly to human body and environment, different from the three synthetic plastics, after waste, under the action of biological environment, can decompose by itself, no matter for people or the environment, belongs to green packaging.
Biodegradable plastic bag is a kind of disposable shopping bag that can be degradable and easily degradable. Degradable plastic bags from the different raw materials and decomposition factors, can be divided into two kinds: one is based on polyethylene plastic, mixed with starch and other biological agents made of plastic bags, also known as biodegradable plastic bags. This plastic bag is decomposed mainly by microbial action. The other is mainly polyethylene plastic, mixed with photodegradative agent and calcium carbonate and other mineral powder made of plastic bags, also known as photodegradative plastic bags. This kind of plastic bags decompose under the action of sunlight.
