ABSTRACT OF THE DISCLOSURE An antistatic and biaxially oriented polypropylene film is manufactured by the steps of (1) adding to crystalline polypropylene, (a) an antistatic agent and (b) a zinc salt of aliphatic acid, (2) melt-extruding the resulting composition to form a sheet or film, (3) orienting the sheet or film both longitudinally and laterally at a temperature below its melting point, and then (4) activating the surface of the resultant antistatic and biaxially oriented film. The film thus obtained possesses a remarkably improved antistatic property and adhesiveness to ink printed on it and to resins coated on it.
