Low Denstiry Polyethylene(LDPE)
Recycled LDPE
Description:
LDPE have Injection molding, extrusion molding, film grade.
Low density polyethylene (LDPE) is the radical polymerization of ethylene under high pressure to obtain thermoplastic. LDPE have transparency, chemical inertness, good sealing ability, good performance of easy molding. The main purpose is for LDPE film products, but also for plastic products, medical devices, pharmaceuticals and food packaging materials, blow molding products.
Applications:
LDPE can be used alone or blended with other members of the polyethylene family use. Widely used in packaging. Construction, agricultural, industrial and consumer markets. LDPE extrusion can be used to make thin, packing bread, agricultural products, snack foods, textiles, durable consumer goods and some industrial products. LDPE is also used as non-packaging films, such as: Agricultural films and shrink films.
