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.

[ What is claimed is:] [1.]1. A pressure-sensitive adhesive construction comprising a substrate and a pressure sensitive adhesive layer wherein the adhesive layer has an upper surface and a lower surface, the upper surface of the adhesive layer is in contact with the substrate, and the lower surface of the adhesive layer has been roughened to a roughness of at least 10 Sheffield units by direct contact of the lower surface of the adhesive layer with a rough second surface.
