FILM HAVING MODIFIED SURFACE CHARACTERISTICS THROUGH USE OF COMBINATION OF SPHERICAL AND LAMELLAR PARTICULATES

摘要

A combination of lamellar and spherical particulates provides a film with desired slip and antiblock characteristics, in the absence of loose dust on the surface of the film. The film exhibits improved Machinability over comparative films having either lamellar or spherical particulates. The invention is also directed to a composition of matter comprising a polymer having the mixture of lamellar and spherical particulates.
