A composite material comprising a base liner with a release layer on at least one surface thereof, and a releasable face layer releasably adhered to the base liner through the release layer by a pressure sensitive adhesive, wherein the base liner has a skin layer on its surface proximate to the release layer which is more difficult to cut than the remainder of the base liner material, such that when the composite is subjected to die cutting or perforating to allow portions of the face layer to be selectively removed, the cutter will not penetrate into or through the base liner to any substantial extent.
