 Plastic bags is defined by the business to provide customers with bags. Plastic bags for its low prices by businesses welcome. But its non-solubility characteristics, making it the number one enemy of environmental protection. Plastic classification according to raw materials can be divided into the following categories:
(1) high-pressure polyethylene plastic bags, (2) low-pressure polyethylene plastic bags, (3) Polypropylene plastic bag, (4) PVC plastic bags.
According to shape classification:
