Patent ID: 8067501

Claim:
A film, comprising: about 10 wt % to about 80 wt % of a propylene-based copolymer having at least 50 wt % propylene-derived units and 5 wt % to 30 wt % alpha-olefin comonomer, based on the total weight of the polymer, said copolymer having a melting point of from about 100° C. to about 170° C., and a melt flow rate of about 200 dg/min or less, as measured according to ASTM D1238-94; and about 20 wt % to about 90 wt % of a polypropylene homopolymer having a melting point of from about 140° C. to about 190° C. and a density of about 0.920 to about 0.970 g/cm 3 , wherein the film has: a thickness of about 10 μm to about 75 μm; a haze of 13% or less, as measured according to ASTM D1003-95; a 1% MD Secant tensile modulus of 55,000 to 150,000 psi, as measured according to ASTM D882-95a; an Elmendorf tear in the machine direction of at least 5 g/mil, as measured according to ASTM D1922-94; an Elmendorf tear in the transverse direction of at least 300 g/mil, as measured according to ASTM D1922-94; and a 45 degree gloss of at least 70, as measured according to ASTM D2457-90.
