Abstract

A process for extruding a thermoplastic composition at higher drawdown rates with less neck-in and greater resistance to draw resonance as well as processes for extrusion coating a substrate and for making an extrusion-cast film are disclosed. The thermoplastic composition is made of at least one substantially linear ethylene polymer used alone or in combination with at least one high-pressure ethylene polymer and/or with at least one heterogeneous linear olefin polymer.
