Abstract:
A monoaxially oriented film including a metallized layer; a gas barrier layer; and a propylene-based random copolymer and at least about 3 wt % of a low density polyethylene which is oriented at least about 2.5 times in one direction and exhibits excellent linear directional tear properties parallel to the orientation direction and excellent heat seal performance in terms of high heat seal strengths and low seal initiation temperature. This film formulation and orientation is suitable for pouch applications requiring high gas and moisture barrier, an “easy-tear” linear tear feature, and excellent hermetic seal properties.
