ABSTRACT:
The tensile properties of elastic polymer films which contain thermoplastic block copolymer compositions and ethylene/vinyl acetate copolymers are improved by replacing some of the ethylene/vinyl acetate with a polyolefin having low crystallinity. The increase in tensile strength occurs without significant loss of elasticity and is most significant when the polyolefin is an ultra-low density polyolefin.
