Patent ID: 7601658

Claim:
Elastic laminate comprising a co-extruded elastic film that has an elastomer support layer and at least one cover layer, and at least one textile outer layer made of a nonwoven, whereby the cover layer has a low layer thickness in comparison with the support layer, and the outer layer is laminated onto the cover layer, wherein the cover layer comprises an elastomer material, which possesses a marked elastic component after tensile stress at room temperature, just like the elastomer support layer, in contrast to thermoplastics, and contains additives for modifying the surface properties, wherein the elastomer material for the cover layer and the support layer consists of a thermoplastic elastomer from the group of block copolymers, elastomer polyuretharies, or mixtures of these elastomers and wherein the nonwoven material of the outer layer comprises non-elastomer fibers that have a significant permanent deformation after stretching, and wherein the outer layer has a stretchable region that has been produced by means of crosswise stretching of the laminate in a meander-shaped roller nip between two profile rollers that engage into one another.
