Degradable plastic bags are completely degraded into carbon dioxide, methane, water, mineralized inorganic salts and other environmental harmless substances under specific circumstances or in natural environment. As a new type of polymer material, degradable plastic bags include many types, and the technical route is also developing.
From the perspective of raw materials, degradable plastic bags can come from either petrochemical raw materials or biomass materials.
From the degradation mechanism, degradable plastic bags include biodegradation, photodegradation, oxidation degradation and so on
From the point of view of degradation effect, degradable plastic bags can be divided into "full" degradation and "partial" degradation.
The main role of degradable plastic bags is to reduce the "white pollution" brought by the utilization rate of non-degradable plastic products to the environment, but also to give better opportunities for sustainable development of the environment, improve the quality of the environment and reduce the pressure of environmental development, and benefit human development.
