ABSTRACT:
Polymeric blends comprising linear low density polyethylene (LLDPE) as the major constituent (60 percent or more), and polypropylene (PP) or ethylene-propylene copolymer having a high propylene content and ethylene-propylene-diene monomer rubber as minor constituents exhibit improved stiffness, tear and impact strength compared to blends of LLDPE and PP. The blends are suitable for use in films.
