Patent ID: 7189299

Claim:
A process for making a pre-label receiver sheet comprising a pragmatic pre-label sheet and a carrier sheet, which pragmatic pre-label sheet comprises, in order, a polymeric image-receiving layer, a pragmatic polymer sheet, and an adhesive layer, which process comprises the following steps: (a) providing a pragmatic pre-label sheet by the following steps: (i) co-extruding a first melt for a polymeric image-receiving layer with one or more other melts for forming a single-layer or multiple-layer pragmatic polymer sheet, wherein said one or more other melts includes a second melt comprising an orientable thermoplastic polymeric material for forming a microvoided layer comprising a void initiator, thereby forming a co-extruded cast composite film comprising at least said image-receiving layer and said microvoided layer; (ii) stretching in at least one direction said cast composite film to reduce the thickness of the layers in the composite film and to produce an oriented composite film, wherein the image receiving layer is less than 15 micrometers thick; and (iii) optionally applying an intermediate sheet, comprising one or more layers, to a back surface of the oriented composite film; (iv) applying a pressure-sensitive adhesive layer, or a laminate comprising a pressure-sensitive adhesive layer, to at least a portion of the back surface of the oriented composite film, on a side opposite the image-receiving layer or, when an intermediate sheet is present, to at least a portion of a back surface of the intermediate sheet, to form the pragmatic pre-label sheet; and (b) providing the pragmatic pre-label sheet with a carrier sheet such that the adhesive layer of the pragmatic pre-label sheet is releasably covered with the carrier sheet in peelable adhesion, thereby forming an integral-separable pre-label receiver sheet.
