Patent ID: 6979495

Claim:
A biaxially oriented multi-layer film oriented in a transverse direction and a machine direction comprising: (a) a core layer comprising at least about 90 wt % of a syndiotactic polypropylene polymer; (b) at least one additional layer adjacent to the core layer comprising a material selected from the group consisting of butene-1-propylene random copolymer, ethylene-propylene block copolymer, nylon, polyester, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, ethylene-propylene-butene-1 random terpolymer containing 1 to 5 wt. % random ethylene and 10 to 25 wt. % random butene-1, low density polyethylene, linear low density polyethylene, medium density polyethylene, high density polyethylene, and blends thereof; and (c) wherein the film has a modulus measured in the transverse direction and a modulus measured in the machine direction and the ratio of the modulus in the transverse direction to the modulus in the machine direction is from about 1.53 to about 1.95.
