ldpe plastic resin pellets virgin granules low density polyethylene for Packing Film
1.Virgin or recycled low density polyethylene (LDPE)
2.Grade:LDPE Film/blowing moulding/injection/Extrusion/pipe grade
3. Application: LDPE Low Density Polyethylene:
LDPE(low density polyethylene) - is used in products and packaging such as plastic bags, milk jugs, detergent bottles, margarine tubs, garbage containers, water pipes, woven bag, raincoat, polyethylene monofilament, woven yarn etc...LDPE resins are made by high pressure autoclave process and mainly used for blown film extrusion and wire coating (cable sheath) etc...They are widely used for applications for general purpose packaging films, heavy duty bags, shrink films, and foams.
