What is a biodegradable plastic bag

Plastic degradation refers to the end of the life cycle of polymers, molecular weight decline, manifested as plastic brittleness, cracking, softness, hardening, loss of mechanical strength, etc., the degradation of ordinary plastic bags takes decades or even hundreds of years, non-degradable plastic bags for landfill or incineration will pollute the environment, in order to protect the environment, there is the invention of degradable plastic bags.

Degradable plastic bags refer to plastic bags that add a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradants, etc.) in the production process to reduce their stability and are easier to degrade in the natural environment.
