ABSTRACT:
Process for applying multi-layer extrusion coatings to substrate at low temperature is described, employing as one extrusion coating layer a defined polyethylene-containing component, and, as the second extrusion coating layer at least one second extrudable polymeric composition. Also provided are novel extrusion coated articles comprising substrate having coated thereon defined polyethylene-containing component and at least one other extrudable polymeric composition. These articles display good adhesion of extrusion coating material to the substrate without the degradation of the extrudable coatings caused by exposure to excessive levels of heat as is required for successful extrusion coating employing prior art materials.
