초록

The specification discloses a method for extrusion coating a lightweight web. According to the method, a length of a lightweight web along with a length of a carrier web is fed to an extruder with the lightweight web positioned atop the carrier web. A polymer film is then extruded onto the combined lightweight web and carrier web to provide an extrusion-coated lightweight web. Thereafter, the extrusion-coated lightweight is separated from the carrier web. Also disclosed are extrusion-coated lightweight webs formed according to the method.
