PE, polyethylene is a high molecular organic compound formed by the addition polymerization of ethylene. It is commonly used as a food contact material. It is non-toxic, tasteless and odorless. It meets the hygiene standards for food packaging. Good gas-proof and insulating properties, and not easy to be damaged. The products are beautiful, strong, impact-resistant and corrosion-resistant. They can hold liquids and solids in chemical raw materials, pesticides, lubricants, coatings, medicine, food, hardware electronics, electromechanical and other industries. thing.

PVC and polyvinyl chloride are widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, foam materials, sealing materials, fibers, etc.
