Abstract

Disclosed is a novel polyethylene composition that is a blend of a polyethylene component having defined properties, a specific quantity of a defined tackifying resin and a very specific minute quantity of a unique amide of a fatty acid. The novel composition can be used in a process for extrusion coating at high speeds and relatively low extrusion coating temperatures with good adhesion to the substrate and dramatically improved chill roll release.
