Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene, produced in 1933 by Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. Its manufacture employs the same method today. Despite competition from more modern polymers, LDPE continues to be an important plastic grade.
Application of LDPE
LDPE is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic parts for computer components, and various molded laboratory equipment. Its most common use is in plastic bags. Other products made from it include:
Trays and general purpose containers, Corrosion-resistant work surfaces, Parts that need to be weldable and machinable, Parts that require flexibility, for which it serves very well, Very soft and pliable parts such as snap-on lids, Six pack rings, Packaging for computer hardware, such as hard disk drives, screen cards, and optical disc drives, Plastic wraps, Plastic bags, Plastic containers, LDPE Pipes, Housewares, Battery cases, Automotive parts, Electrical components.

LDPE is widely used in packaging, construction, agriculture, and medical industries due to its unique properties and versatility. Common applications include film and sheet production for packaging, plastic bags, agricultural films, medical tubing, and wire and cable insulation.
LDPE is recyclable and can be processed into new products through mechanical or chemical recycling methods, reducing the consumption of virgin plastics and diverting waste from landfills. Its lightweight, flexible, and durable nature makes LDPE an environmentally friendly choice for packaging and other applications.
LDPE offers several advantages over other types of plastics, including excellent flexibility, impact resistance, and sealability. Its ability to withstand low temperatures and resist chemicals makes LDPE ideal for applications requiring moisture barrier properties and protection against environmental factors.
