Common problems of degradable plastic bags

　　With the increasingly serious white pollution caused by plastics, environmental protection has been paid more and more attention by the public. Judging from the general trend of the current plastic industry, traditional plastic bags can no longer meet the development requirements of current energy conservation and environmental protection. Biodegradable plastic bags are replacing traditional plastics as a new development direction. At the same time, due to the strict "plastic ban", degradable plastic bags have officially come into people's sight. In fact, the environmental bags we are concerned about are equivalent to degradable plastic bags. What do we mean by degradable plastic bags?

　　According to the degradation mechanism, degradable plastic bags can be divided into three categories: photo degradable plastic bags, degradable plastic bags and water degradable plastic bags.

　　Photodegradable plastic bag: The photosensitizer is mixed in the material of the plastic bag, and the plastic bag is gradually decomposed under the effect of sunlight. However, its disadvantage is that the degradation time is affected by light and climate and cannot be controlled.

　　Biodegradable plastic bag: refers to the plastic that can be decomposed into low molecular compounds by bacteria, molds, algae and other microorganisms in nature under certain conditions. This kind of plastic is easy to store and transport, and has a wide range of uses.

　　Degradable plastic bag: A plastic bag that can be dissolved in water due to the addition of water absorbing substances.
