<p>Film-forming means (12, 14, 16) are coextruded to form all-plastic multilayer liners and facestocks for pressure-sensitive labels, decals, signs, bumper stickers, and other products formed from sheet and roll stock. A filler (22, 24) differential in the charges for the liner coextrusion differentially affects the roughness of the liner forms. 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.</p> |
