Patent ID: 7501361

Claim:
A tape for diaper closures, comprising an elastic carrier film that has a preferred elongation direction and comprises a multi-layer co-extrusion film with a core of a thermoplastic elastomer and an adhesion-imparting layer, at least one cover layer that is laminated on the elastic carrier film, the cover layer comprising a spun-bonded fabric having filaments, said filaments having a filament core of a thermoplastic elastomer, and a filament mantle of a non-elastic thermoplastic polymer that has been deformed as a result of pre-stretching, and a hook tape having male closure elements, said hook tape being attached to the cover layer by gluing or bonding and forming a hook and loop closure with female closure elements that are attached on a front waistband of a diaper, wherein the non-elastic thermoplastic elastomer within the filaments is 20-60 wt-% of the total weight of the fabric, and wherein the fabric has a defined elongation limit resulting from pre-stretching in the preferred elongation direction by means of an elongation of the fabric; and wherein the carrier film and the cover layer are connected by an elastic hot melt adhesive that is applied in points, in a grid or in strips that run in lines crosswise to the elongation direction.
