Abstract

The invention concerns a certain class of polymers, their production into films and applications for their use. These polymers have unique properties which make them particularly well suited for use in polymeric films. These films are very useful in applications requiring heat sealability, particularly those applications containing an ionomer film. It has been discovered that polymers derived from metallocene catalyst systems surprisingly heat seal extremely well, as compared to polymer produced by conventional Ziegler-Natta catalysts, to a class of polymers known as ionomers.
