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.

In order to prevent degradation of appearance, prevent a decrease in flexibility, and improve non-elasticity in a non-stretchable region in an elastic film stretchable structure, the invention is characterized by having an elastic film stretchable structure (20X) formed by stacking an elastic film (30) between a first sheet layer (20A) and a second sheet layer (20B), wherein a region having the elastic film stretchable structure (20X) includes a non-stretchable region (70) and a stretchable region (80) provided at least at one side of the non-stretchable region (70) in a stretching and contracting direction, the stretchable region (80) being stretchable in the stretching and contracting direction, the first sheet layer (20A) and the second sheet layer (20B) are joined via through holes (31) penetrating the elastic film (30) at the large number of sheet bond portions (40) arranged at intervals, and the non-stretchable region (70) does not have a section in which the elastic film (30) linearly continues along the stretching and contracting direction, due to presence of the through holes (31), even though the elastic film (30) continues in the stretching and contracting direction.

The disclosure also relates to an hygienic absorbent article provided with at least one refastenable side seam. The disclosure also relates to a process and an apparatus for carrying out one or more operations on elastic panels usable for making an hygienic absorbent article provided with at least one refastenable side seam.

The invention relates to a laminated assembly including a support layer (32) and an anti-slip strip (34), the anti-slip strip (34) including an elastomeric material, the support layer (32) and the anti-slip strip (34) being laminated together, the anti-slip strip (34) including a base (34A) and a plurality of protruding elements (34B) extending from the base (34A) and the plurality of protruding elements (34B) protruding from a face (30A) of the laminated assembly (30). The invention also relates to a diaper including such a laminated assembly (30) and a process for manufacturing the laminated assembly (30). The invention also relates to a diaper including such an assembly and a process for manufacturing such an assembly.

The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. In particular, discrete mechanical bonds are applied to a first substrate and a second substrate to secure elastic strands therebetween, wherein the discrete bonds are arranged intermittently along the machine direction. During the bonding process, heat and pressure are applied to the first substrate and the second substrate such that malleable materials of the first and second substrates deform to completely surround an outer perimeter of a discrete length of the stretched elastic strand. After removing the heat and pressure from the first and second substrates, the malleable materials harden to define a bond conforming with a cross sectional shape defined by the outer perimeter of the stretched elastic strand.

A disposable absorbent article may include a first waist region, a second waist region, a crotch region disposed between the first and the second waist regions, and a chassis having a topsheet, backsheet, absorbent core, and chassis periphery. The chassis periphery has a varying width, WV.

The present invention includes disposable absorbent articles, such as disposable undergarment, diapers, other garments, and wound care dressings, having an elastomeric material disposed between two substrate layers and an absorbent core system that disposed on top of or between the two substrate layers. This invention may also include a disposable article having an elastomeric material disposed between two substrate layers without an absorbent core. The inclusion of an stretch adhesive in the construction of the article in various portions of the article (e.g., fastening tabs, front and/or rear sections, entire article, etc.) results in improved securement of the article to a wearer for reducing the risk of leakage and further improving comfort for the wearer. Furthermore, the inclusion of a stretch adhesive can provide a smooth contoured fit to a wearer, thereby improving appearance and self-confidence for the wearer.

There is provided herein an incontinence diaper (2) which has rear lateral sections (22) of the incontinence diaper (2) which can be brought into overlapping arrangement with a front region (12) exterior, to which the lateral sections can then be removably adhered via respective closure means (28). The rear lateral sections (22) have an elastic region (42), and the extension (Q) of the rear lateral sections (22) comprises a proximal half (38) which adjoins the rear longitudinal edge (18) and a freely ending distal half (40) in the transverse direction (10), and wherein, the respective elastic region (42) is arranged completely within the proximal half (38) and has a distance of maximally 30 mm from the rear longitudinal edge (18) in the transverse direction (10), and each rear lateral section (22) is substantially non-stretchable in the entire distal half (40).
