Abstract
A reversibly extensible polymeric film is hot formed, as by coextrusion, using selected polymeric materials that provide discrete areas of elastic and inelastic polymeric materials arranged in laterally spaced and longitudinally elongated lanes or stripes connected by integrally formed joints therebetween. The elastic materials comprise block polymers selected from tetrablock, triblock and diblock polymers, and the inelastic material is selected from polyolefins such as polyethylene, polypropylene, poly(ethylene-propylene), poly(ethylene-vinyl acetate), poly(styrene-butadiene), or copolymers or blends thereof.
