Therefore, environmentally friendly and convenient degradable plastic bags have become the solution. The only way to problem.

The degradable bag is a kind of disposable shopping bag that is "degradable and easily degradable". Biodegradable plastic bags can be divided into two types according to their raw materials and decomposition factors:
