Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people’s daily life and are often used to hold other items. It is widely used because of its cheapness, extremely light weight, large capacity, and easy storage. However, it is banned from production and use by some countries because of the extremely long degradation cycle and difficult handling of plastic bags.
