ABSTRACT:
A slip-coated thermoplastic film is disclosed wherein the slip coating applied is essentially an aqueous wax emulsion. The wax emulsion is preferably applied to a thermoplastic film such as polypropylene between the machine direction and transverse direction stretching process. The resultant slip-coated film has low haze, non-blocking, and consistently low coefficient of friction for good machinability.
