Films containing LLDPE having a high modulus and good tear strength for the high modulus and improved processing conditions are obtained by blending minor amounts of polystyrene or other aromatic polymer, and polypropylene with the LLDPE.

Blends of LLDPE, polypropylene and aromatic polymers and high modulus

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 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 the films.

Films of LLDPE, PP and EPR having improved stiffness, tear and impact

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.
