Generally speaking, there are no completely environmentally friendly plastic bags. It can only be that some plastic bags are easier to degrade after adding some ingredients. That is degradable plastic. Then the biodegradable plastic bag manufacturers will take you to briefly understand the composition of environmentally friendly plastic bags.

Adding a certain amount of additives (such as starch, modified material starch or other cellulose, photosensitizers, biodegradants, etc.) degraded in the natural environment. At present, there are 19 units in the Beijing area that research and develop or produce degradable plastics. Experiments have shown that most degradable plastics begin to become thinner, lose weight, decrease in compressive strength after being exposed to the general natural environment for 3 months, and slowly break into pieces. If these fragments are buried in garbage or soil, the degradation effect will not be obvious.

There are four disadvantages of using degradable plastics:

One is to consume more food;

Second, the use of degradable plastic products still cannot completely eliminate "visual pollution";

Third, due to technical reasons, the use of degradable plastic products cannot completely solve the "potential harm" to the natural environment;

Fourth, degradable plastics cannot be recycled because they contain special additives.
