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.

[ What is claimed is:] [1.] A film comprising an outer layer comprising at least one member selected from the group consisting of ethylene/vinyl acetate copolymer, ethylene/alpha-olefin copolymer, and polyamide, the outer layer further comprising:(A) inorganic spherical particulates having an average particle size of from about 0.1 to 30 microns; and(B) inorganic lamellar particulates having an average aspect ratio of from about 5:1 to 40:1, and a major dimension of from about 0.1 to 15 microns;wherein the spherical particulates and the lamellar particulates are present in an outer film layer and on an outer surface of the film.
