Application:
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,wovenyarn etc.. LDPE resins are made by high pressure autoclave process and mainly used for blown film extrusionand wire coating (cable sheath) etc.. They are widely used for applications for general purpose packaging films,heavy duty bags, shrink films, and foams.
