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 tile cost/benefit characteristics of candidate materials considering the functional or operational requirements of the layer in question.
