A void-containing polyester-type film and its laminate

摘要: A void-containing polyester-type film is obtained by drawing a resin composition sheet consisting of polyester, and thermoplastic which not compatible with the polyester in at least one direction. The this invention has base material mainly fine particles are dispersed into material, voids formed around particles. surface layer having 3 μm or more thickness, void percentage 4% volume less an area thickness from its surface, average 8% to 50% volume. excellent softeness, lightness, hiding power, strength. can be used as for label, etc.
