"Plastic drums are commonly made from materials like polyethylene and polypropylene through blow molding and injection molding processes. They are used for the outer packaging of liquid and solid items in industries such as chemical, food, hardware, electronics, and mechanical and electrical engineering in Shanghai."

Plastic drums are commonly used for storing and transporting various liquids, and they possess excellent characteristics for packaging hazardous materials. They are not easily broken, do not rust, and are lightweight, with good oil and strong corrosion resistance. They are often used for packaging hazardous materials that require insulation, moisture resistance, pressure resistance, and corrosion resistance. The materials used for plastic drums are typically made from blow molding, injection molding, vacuum forming, and rotational molding of polyethylene, polypropylene, polyester, and other plastics. They are widely used for containing liquids and solids in industries such as chemicals, food, hardware, electronics, and electromechanical.
