Abstract
Compositions suitable for use in extrusion coating are claimed. The compostions comprise a mixture of a homogeneous ethylene polymer and a heterogeneous ethylene polymer together with a high melt strength polyolefin. Film layers made from the compositions have improved neck-in and excellent heat sealing characteristics.
