An absorbent article (10, 110) can include a waist containment member (54) with a first longitudinal side edge (72), a second longitudinal side edge (74), a proximal portion (76), an intermediate portion (77), and a distal portion (78). The proximal portion (76) can be coupled to the chassis (11) of the absorbent article (10, 110). The intermediate portion (77) can be free to move independent of the proximal portion (76) and the distal portion (78) and free to move independent of the body facing surface (19) of the chassis (11) to provide a containment pocket (82) for containing body exudates. The distal portion (78) can be disposed underneath the intermediate portion (77) when the absorbent article (10, 110) is in the stretched, laid-flat configuration. The waist containment member (54) can also include a first lateral tack-down region (83a) and a second lateral tack-down region (83b).

The absorbent core comprises a first and second layer comprising pulp fibres. The diaper is either manufactured of wholly or partially renewable resources, at the same time can substantially decompose in a compost site, and substantially biodegrade in a conventional landfill.

The present application discloses novel hot-melt adhesive formulations, with excellent processability, even in processes at high line-speed and at a relatively low temperature, the formulations suitable for strongly bonding substrates that have openings, holes, voids or pores, both macroscopic and microscopic ones, like perforated plastic films, both with bidimensional or tridimensional structure; fibrous substrates, both woven and non-woven; porous plastic films, and the like, all mentioned substrates being widely used for the manufacturing of absorbent hygienic articles. The hot-melt formulations include, as their main or even unique constituent, at least one polymer composition formed by two polyolefins, substantially non-stereospecific, as showed by the low value of their crystallization enthalpy at time zero, the polyolefins having average Number Molecular Weights Mn that do not differ for more than about 6,000 g/mole, being the single average Number Molecular Weights of said polyolefins ranging from about 3,000 g/mole and about 30,000 g/mole.

The present invention is intended to prevent cutting of the resilient and elastic members by a welding process. The foregoing issue is solved by passing a first sheet layer, a second sheet layer, and elongated resilient and elastic members continuously disposed in an MD direction between the two sheet layers, between a first roll with joint convex parts provided at circumferential intervals on an outer peripheral surface and a second roll opposed to the first roll, and pressurizing and heating the first sheet layer and the second sheet layer to form sheet joined sections by welding the first sheet layer and the second sheet layer in such a manner as to cross the resilient and elastic members and have MD-direction intervals therebetween, wherein circumferentially continuous grooves are formed on a pressurization surface of the second roll, passage sections of the resilient and elastic members are pressurized and heated in positions including the grooves of the second roll, and non-passage sections of the resilient and elastic members are pressurized and heated in positions not including the grooves of the second roll.

Methods for forming absorbent articles and side seam bonds of absorbent articles are described. In one embodiment, a method of forming absorbent articles may comprise advancing webs, coupling absorbent cores to the webs intermittently to form open absorbent article chassis, folding the absorbent article chassis, forming a first side seam bond first bond pair between a first region of the webs and a second region of the webs with a first ultrasonic horn, forming a second side seam bond of the bond pair between the first region and the second region with a second ultrasonic horn, the first bond being associated with a first absorbent article chassis and the second side seam bond being associated with a second absorbent article chassis, and cutting the folded absorbent article chassis between the first bond and the second bond to separate the first absorbent article chassis from the second absorbent article chassis.

A method for providing successive individual combination belt structures each comprising a fastening component includes providing a machine-direction continuous strip of web material having a pair of machine-direction outer side edges, opposing side margin portions, and a cross-direction width therebetween. The web material is conveyed along the machine direction to fastening component process equipment to continuously affix successive fastening components to the web material. The web material is conveyed to cross-direction cutting equipment to cut individual combination front belt structures from the web material along predominately cross-direction cut lines.

A disposable diaper has front and rear waist regions, a crotch region, and an absorbent chassis. The absorbent chassis includes an absorbent structure and a pair of side flaps. Each of the side flaps has layered sheet materials and includes a distal edge, a cuff branch line between the side edge of the absorbent structure and the distal edge, a leg-opening elasticized area between the cuff branch line and the distal edge, and a leakage-barrier cuff branched from the cuff branch line and intersecting with the leg-opening elasticized area. The leakage-barrier cuff has a free edge parallelly-spaced from the cuff branch line. The distance from the cuff branch line to the distal edge is larger than from the cuff branch line to the free edge. The number of sheet material layers included in the leg-opening elasticized area is larger than in the leakage-barrier cuff.

A method for producing elasticized composite side panels and non-elasticized side panels, comprising: feeding a continuous web of a first non-extensible material having longitudinal side edges along a first direction parallel to a longitudinal axis of said web, forming in said web, in a position within said longitudinal edges, and at a pitch, a plurality of oblong openings having a major axis substantially parallel to the longitudinal axis of said web, each opening having a maximum transverse dimension with a first length, a maximum longitudinal dimension with a second length, and two longitudinal end zones, forming a plurality of rectangular elements of elastic material having in a relaxed condition two minor sides with a first dimension greater than said first length and two major sides with a second dimension at least equal to said second length of said oblong openings, said elements of elastic material being elastically extensible at least along the first dimension, transferring each of said rectangular elements of elastic material in a relaxed condition onto said continuous web at each oblong opening and in a substantially centered position with respect thereto, welding each rectangular element to said continuous web along at least the respective longitudinal edges superimposed on the longitudinal edges of each oblong opening, so as to form a continuous composite web, making transverse cuts at predetermined intervals on said continuous composite web so as to remove transverse portions from said continuous composite web comprising the longitudinal end zones of each oblong opening and the corresponding minor sides of each respective rectangular element of elastic material, to form alternately individual elasticized composite panels comprising said elastic material and individual non-elasticized panels not comprising said elastic material.
