Introduction of LDPE
Low-Density Polyethylene (LDPE) is a versatile thermoplastic polymer known for its flexibility, toughness, and wide range of applications. LDPE belongs to the polyethylene family of polymers and is one of the most widely used plastics due to its ease of processing, affordability, and unique properties. It is produced through the polymerization of ethylene monomers, with a lower density and more branched molecular structure compared to other types of polyethylene.
Price: mid-range cost material
Application: packaging films, plastic bags, containers, squeezable bottles, toys, medical devices, various consumer goods, etc.
Recommended Wall Thickness: 1mm-3mm
