Abstract: A novel type of low temperature heat-sealable bi-axially oriented polypropylene composite film and a process for the production thereof are disclosed. The composite film is characterized by having on at least one of the outer surfaces thereof a uni-axially or bi-axially oriented extremely thin continuous layer of a primary higher fatty acid amide or an N-substituted higher fatty acid amide formed through the sequential coating and orientating, and it shows well-balanced excellence in all properties required for such films including lubricity, anti-blocking property, anti-scratch property and low temperature heat sealability.
