An absorbent article includes a chassis. The chassis includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, and at least one elastically elongatable panel joined to the chassis. The elastically elongatable panel includes a stretch laminate having layers that are joined by ultrasonic bonding. The stretch laminate has at least one cover layer and an elastomeric film attached to the cover layer. The elastomeric film has two surfaces and a skin on at least one of the surfaces. The stretch laminate includes at least one anchoring zone and at least one stretch zone. The stretch laminate may include activation stripes and/or a plurality of wrinkles.

Absorbent articles comprising stretch laminates

An absorbent article includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, and at least one elastically elongatable panel joined to the chassis. The elastically elongatable panel includes a stretch laminate having layers that are joined by ultrasonic bonding. The stretch laminate has at least one cover layer, an elastomeric film attached to the cover layer, the elastomeric film having two surfaces and a skin on at least one of the surfaces. The stretch laminate has at least one anchoring zone and at least one stretch zone. A portion of the skin is located in the anchoring zone and has a plurality of wrinkles, and the wrinkles have furrows.

An absorbent article includes a chassis includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, and at least one elastically elongatable panel joined to the chassis. The elastically elongatable panel includes an ultrasonically bonded stretch laminate. The stretch laminate includes a first nonwoven and a second nonwoven, and an elastomeric film sandwiched between the first and second nonwovens. The elastomeric film has two surfaces and a skin on at least one of the surfaces. The stretch laminate further incudes a zone that is unactivated. The laminate is elastically extensible in a stretch direction. The elastomeric film includes activation stripes.

An elastic film has a perforation formed by perforation holes that are elongated along a preferred expanding direction in the unexpanded state, wherein the ratio of the length of the perforation holes determined along the preferred expanding direction to a width of the perforation holes determined perpendicular thereto amounts to at least 3:2. The elongation at break along the preferred expanding direction is at least twice as high as the elongation at break determined perpendicular thereto along the width of the perforation holes.

Elastic film and method for producing an elastic layer material

An absorbent article includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, and at least one elastically elongatable panel joined to the chassis. The elastically elongatable panel includes an ultrasonically bonded stretch laminate. The stretch laminate has at least one cover layer; and an elastomeric film having two surfaces and a skin on at least one of the surfaces. The stretch laminate has a first zone that is not elastically extensible along a stretch direction and a second zone that is elastically extensible along the stretch direction; and at least a portion of the skin of the elastomeric film is located in the first zone and wherein said portion of the skin has a plurality of wrinkles and the wrinkles have furrows.

In the second zone, the laminate is elastically extensible in a stretch direction. In the first zone, the laminate is unactivated and the elastomeric film comprises activation stripes.

An absorbent article includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, and at least one elastically elongatable panel joined to the chassis. The elastically elongatable panel includes a stretch laminate that has at least one cover layer, an elastomeric film attached to the cover layer, the elastomeric film having two surfaces and a skin on at least one of the surfaces, and an adhesive disposed between the skin and the cover layer. The stretch laminate has at least one anchoring zone and at least one stretch zone, the skin that is located in the anchoring zone has a plurality of wrinkles, and the wrinkles have furrows, and at least some of the adhesive is disposed in at least some of the furrows. An absorbent article including the stretch laminate is also provided.

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

An absorbent article includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, and at least one elastically elongatable panel joined to the chassis. The elastically elongatable panel includes a stretch laminate that has at least one cover layer, an elastomeric film attached to the cover layer, the elastomeric film having two surfaces and a skin on at least one of the surfaces, and an adhesive disposed between the skin and the cover layer. The stretch laminate has at least one anchoring zone and at least one stretch zone, the skin that is located in the stretch zone has a plurality of wrinkles that are substantially perpendicular to a stretch direction of the stretch laminate, and the wrinkles have furrows, and at least some of the adhesive is disposed in at least some of the furrows.

A liquid-dispensing pad has a perforated generally elastic film forming a front wall, a liquid-impervious plastic rear wall, a weld peripherally securing the front wall to the rear wall, and a liquid-retaining core between the front and rear walls. The perforated film is a coextruded film having an elastic inner layer turned toward the core and an inelastic outer cover layer turned away from the core. This cover layer forms an outer face of the liquid-dispensing pad and is composed of polyolefin. A thickness of the cover layer is less than 15 &#x3bc;m, and a thickness ratio of the elastic inner layer to the inelastic outer cover layer is at least 10:1.
