Product Name

Low-Density Polyethylene

Category

Food Grade Plastic

Description

Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene. Despite its designation with the recycling symbol, it cannot be as commonly recycled as No. 1 (polyethylene terephthalate) or 2 plastics (high-density polyethylene).

Melting Point

102-113 °C.

Density

0.915-0.960 kg/m³

Application

Juice and milk cartons are made of liquid packaging board, a laminate of paperboard and LDPE (as the waterproof inner and outer layer), and often with of a layer of aluminum foil (thus becoming aseptic packaging).
Playground slides, Plastic wraps, Plastic bags, Plastic containers, LDPE Pipes.

Feature

Compared to many other resins, LDPE is thinner. Although it commonly finds use in film applications where heat sealing is needed, it is also used for rigid applications. The material is tough, flexible, and chemical and impact resistant.
