Closure elements that include elastic and non-elastic regions are disclosed as well as absorbent articles that include closure elements.

Absorbent article with elastically elongatable panel

A coextrusion film has a core layer made of thermoplastic elastomer, and first and second outer layers sandwiching the core layer. The outer layers are each formed from a polymer having a lower elasticity than the thermoplastic elastomer of the core, each have a layer thickness of less than 15 &#x3bc;m, each have a density of less than 0.800 g/cm, and each have more than 500 gas-filled cells per 1 cubic millimeter of volume.

Coextrusion film and method of mixing

A closure element comprising a composite web comprising: a nonwoven web; an elastically extensible film strip joined to the top surface of the nonwoven web; a nonwoven material disposed on top of the film strip; and a strip of a fastening material disposed on top of the nonwoven web, wherein the nonwoven material overlaps the edges of the strip of fastening material and the strip of fastening material at its edges overlapped by the nonwoven material has projections which extend into the nonwoven material, as well as absorbent articles that include closure elements.

Absorbent article with compound material web

A composite web, with elastic and inelastic regions, is formed to separated or punched into diaper closure elements. The composite web includes nonwoven web which forms a first outer side of the composite web. On the composite web are disposed spaced-apart, elastically stretchable foil strips. A nonwoven material covers the elastically stretchable foil strips on a second outer side of the composite web. At least one inelastic strip of a hook material bridges a region between two adjacent, elastically stretchable foil strips. The nonwoven material overlaps edges of the strip of hook material. The strip of hook material has projections on the edges thereof that are overlapped by the nonwoven material. The projections extend into the nonwoven material.

Composite web

A label film is formed by means of extrusion and has a layer that forms the surface, on a first side, composed of polyethylene with a proportion of at least 70 wt.-%, preferably at least 85 wt.-% high-density polyethylene, wherein the film thickness amounts to less than 75 &#x3bc;m. According to the invention, the 60&#xb0; reflectometer value on at least the first side of the label film, determined according to DIN 67 530, is greater than 80, preferably greater than 90.

Label film

A laminated web from which diaper closure elements may be punched is made by first applying at least two pairs longitudinally extending and transversely spaced bend-resistant strips to a first longitudinally extending nonwoven tape. Then a respective longitudinally extending strip of an elastically stretchable polymer is applied to the first nonwoven tape between each of the pairs of the bend-resistant strips with the polymer strip partially overlapping both of the bend-resistant strips of the respective pair. A second longitudinally extending nonwoven tape that covers and extends transversely to both sides of the polymer strip is applied over the bend-resistant strips and the polymer strips to form a laminate with the polymer strip between the first and second nonwoven tapes.

Diaper closure and method of making same

A method for producing an elastic laminate material web that has elastic and non-elastic regions and has non-woven fabric on both surfaces of the web. In between the two surfaces, there are film strips of an elastic film. One surface of the web consists of a planar non-woven fabric layer and is connected with non-woven fabric that is disposed on the opposite surface of the web in areas between the film strips. Each film strip is connected with a non-woven fabric layer to form a laminate strip. The laminate strips are glued to the planar non-woven fabric layer on their film side, and the non-woven fabric that is connected with the planar non-woven fabric layer between the laminate strips is in the form of non-woven fabric strips that run parallel to the laminate strips. The non-woven fabric strips overlap the non-woven fabric layer of the laminate strips in edge regions of the laminate strips.
