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.

Reversibly extensible film

A process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; casting a liquid plastisol formulation onto the adhesive; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the adhesive; and, winding the resulting tape laminate onto rolls. Also, a process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; disposing a barrier film onto the dried adhesive; casting a liquid plastisol formulation onto the barrier film; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the barrier film; and, winding the resulting tape laminate onto rolls.

Process for manufacturing tape products

A one stage process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; casting a liquid plastisol formulation onto the adhesive; fusing, and in the case of a foam tape expanding, the plastisol formulation to form a thermoplastic layer on the adhesive; and, winding the resulting tape laminate onto rolls.
