Polyethylene bags are made of polyethylene. PE is the abbreviation of polyethylene, which is a thermoplastic resin polymerized from ethylene. It is a transparent plastic bag, which can be used to package clothes, bags and electronic products. Polyethylene is odorless and nontoxic, feels like wax, and has excellent low temperature resistance, good chemical stability and resistance to most acid and alkali corrosion. Insoluble in general solvents at room temperature, low water absorption and excellent electrical insulation.

Polyethylene can be processed by molding ordinary thermoplastics. Polyethylene is widely used, mainly for making films, packaging materials, containers, pipes, monofilaments, wires and cables, daily necessities and so on. , which can be used as high-frequency insulating material for TV and radar. Polyethylene is divided into high density polyethylene, low density polyethylene and linear low density polyethylene according to polymerization method, molecular weight and chain structure.
