An absorbent article may be constructed by printing on an unstretched web that forms a portion of the side panels. Seams may be formed by attaching the side panels to a chassis. The side panels and the chassis may have different elastic properties. The absorbent article may also comprise first and second waistbands.

An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer. And, the first outer layer may comprise an amount of draw down polymer greater than about 45 wt %.

A stretchable structure of an absorbent article includes a stretchable region and a non-stretchable region. A laminate of a first sheet layer, second sheet layer, and elastic film between the first and second sheet layers extends over the stretchable and non-stretchable regions. The first and second sheet layers are bonded to each other at a large number of dot-like joints via through holes formed in the elastic film stretched along the surfaces of the first and second sheet layers in a stretchable direction. The dot-like joints are arrayed at intervals in the stretchable direction and a direction perpendicular to the stretchable direction. An end of the stretchable region adjacent to the non-stretchable region is a buffer stretchable section. The area rate of dot-like joints in the buffer stretchable section is larger than the area rate of dot-like joints in the main section not including the buffer stretchable section.

A pant-type absorbent article, such as a pant diaper, a sanitary pant or incontinence pant, includes a front portion, a back portion and a crotch portion, wherein lateral side portions of the front portion and back portion are superposed so that their inner surfaces face each other and being joined to each other along side seams. At least part of said front and back portions comprises an elastic laminate including first and second fibrous layers and an elastic film layer located therebetween, the first fibrous layer forms an inner wearer-facing side of the elastic laminate having a basis weight of between 13 and 30 g/m.sup.2 and the basis weight of the first fibrous layer is between 10 and 300% higher than the basis weight of the second fibrous layer, and wherein the first fibrous layers face each other along said side seams.

An absorbent article may be constructed by printing on a web that forms a portion of the side panels using a first printing method; and by printing on a backsheet using a second printing method. Seams may be formed by attaching the side panels to a chassis and by attaching the side panels to each other to form a waist opening and leg openings.

An absorbent article is provided with a central elastic material for positioning in a state in which it is extended in the front/rear direction in the outer direction in relation to an absorbent body, and an elastic material cover sheet which abuts the outer direction side surface of the central elastic material. The elastic material cover sheet covers an extension region where the central elastic material is positioned in an extended state, and a non-extension region where the central elastic material is positioned in a non-extended state. An adhesive agent for fixing in the extended state is coated onto the central elastic material of the extension region. An adhesive agent is coated onto at least the non-extension region of the outer direction side surface of the elastic material cover sheet, and the adhesive agent coated onto the outer direction side surface penetrates to the inner direction side surface of the elastic material cover sheet.

A disposable absorbent article of a brief or pull-up type incorporates a breathable laminate material composed of two layers. The laminate is an elastic material and may include non-elastic portions created by deactivating the material. The laminate material may be made breathable by the ultrasonic bonding process used to create the laminate. A third layer is adhered or bonded to the laminate and with leg elastics positioned between the laminate that the third layer. The absorbent article includes an absorbent assembly that overlaps with the non-elastic portions of the laminate.

Provided is a stretchable laminate including an elastomer layer and a non-woven fabric layer arranged on at least one side of the elastomer layer, in which interlayer delamination does not occur between the elastomer layer and the non-woven fabric layer even when a load is applied onto a surface, on which the elastomer layer and the non-woven fabric layer are bonded onto each other, in a substantially perpendicular direction. Also provided is an article including such stretchable laminate. The stretchable laminate of the present invention includes: an elastomer layer; and a non-woven fabric layer arranged on at least one side of the elastomer layer, the stretchable laminate further including a hot-melt pressure-sensitive adhesive between the elastomer layer and the non-woven fabric layer, the hot-melt pressure-sensitive adhesive containing an olefin component.

A pad-shaped absorbent article includes a liquid-permeable topsheet, a backsheet and an absorbent body between the top- and backsheets. The topsheet, the backsheet and the absorbent body respectively have an extensibility in the longitudinal direction. The extensibility of at least one of the topsheet and the backsheet is an elastic extensibility. The sheets have first regions extending across the absorbent body in the transverse direction to express an elastic extensibility and second regions having an elastic extensibility in the longitudinal direction lower than that of the first regions. The absorbent body has a plurality of slits extending in the transverse direction and expresses an extensibility in the longitudinal direction, when the article is subjected to tensile forces opposite in the longitudinal direction so as to open the slits and the absorbent body is arranged so that at least one of the slits overlaps with the first regions
