Abstract

An elastomeric film includes a first layer co-extruded with a second layer. The first layer includes a single-site catalyzed ethylene-alpha olefin copolymer having a density of about 0.860 to about 0.900 grams per centimeter. The second layer includes a styrene copolymer selected from styrene-butadiene-styrene, styrene-isoprene-styrene, styrene-ethylene/butylene-styrene, styrene-ethylene/propylene-styrene, or styrene-(ethylene/propylene)-styrene-(ethylene/propylene). The first layer may optionally include filler particles. An extensible laminate including the elastomeric film is also disclosed.
