ABSTRACT:
A biaxially oriented polypropylene film is provided which exhibits improved heat-seal strength and good optical clarity. The polypropylene film is characterized by having on at least one surface thereof a continuous coating of a heat-sealable film layer comprising a copolymer of ethylene and methylacrylate. The lamination may be formed by machine direction orientation of an uncoated polypropylene base web followed by extrusion coating with the copolymer material and subsequent transverse direction orientation of the combined layers.
