Abstract
Abstract Film-forming means are coextruded to form all plastic multilayer liners and facestocks for pressure-sensitive labels, tapes, decals, signs, bumper stickers, and other products formed from sheet and roll stock. Fill means in a charge for the liner coextrusion affects stiffness and dimensional stability of the liner and/or affects the roughness of a liner face or faces. The film materials of the layers of the constructions are selected according to the cost/benefit characteristics of candidate materials considering the functional or operational requirements of the layer in question.

A method for making and mounting labels, tapes and signs comprising the steps of providing a plurality of at least two charges of film-forming resin including a core or base charge associated with the forming of a core or base and at least one skin charge associated with the forming of at least one skin, coextruding said charges to thereby form a filled coextrudate constituting a multilayer polymeric liner and comprising cojoined layers including a core or base layer and at least one skin layer, and including the step of roughening a face of the coextrudate to a roughness of at least about 10 Sheffield units in its finally formed state, temporarily contacting the roughened face of the coextrudate against one face of an adhesive layer which has been, is being, or is to be permanently joined at its opposite face to facestock to impart the roughness of the coextrudate face to said one face of the adhesive layer, or coating the roughened face of the coextrudate with an adhesive layer which is being, or is to be permanently joined at its opposite face to facestock to impart the roughness of the coextrudate face to said one face of the adhesive layer, and subsequently removing the coextrudate from the adhesive layer to expose said one face of the adhesive layer and then contacting said one face of the adhesive layer against a substrate to thereby mount said facestock on the substrate, with said imparted roughness of said one face of the adhesive layer preventing or minimizing air entrapment between said one face and said substrate during said mounting step.
