Film grade linear medium density polyethylene base resin
Basic Resin for MDPE Film
Product performance:
This product is a high molecular weight linear low density film grade polyethylene resin containing antioxidants. Has good processing performance, excellent drafting performance and superior physical and mechanical properties. The resulting film has only high dart impact strength, and has good yield tensile strength and stiffness. Its toughness and cold resistance make it suitable for use in cold places or for refrigeration. The film also has high sealing strength and thermal adhesion. Compared with the traditional polyethylene film, its excellent mechanical properties will improve the characteristics of such films or greatly save raw materials (thin film thickness).
The main purpose:
Industrial liners, shrink-wrapped, wrapped-wrap, frozen-pack or agricultural applications.
