The present disclosure relates to absorbent articles having a waist gasketing element, with the gasketing element having an adhesive zone and one or more adhesive-free zones. At least a portion of the waist gasketing element is adhesively attached to a chassis of the absorbent article. Additionally, a portion of the waist gasketing element is mechanically attached to a portion of the absorbent article.

Absorbent article having a waist gasketing element

An absorbent article comprises a topsheet on the wearer-facing side, a backsheet on the garment-facing side, and an absorbent core positioned between the topsheet and the backsheet. The absorbent core comprises an absorbent material comprising a superabsorbent polymer, a core wrap enclosing the absorbent material, and a first channel disposed on one side of the longitudinal axis and a second channel disposed on the other side of the longitudinal axis.

Absorbent article with core-to-backsheet glue pattern comprising two glues

The present disclosure relates to absorbent articles having a waist gasketing element, with the gasketing element having an adhesive zone and one or more adhesive-free zones. At least a portion of the waist gasketing element is adhesively attached to a chassis of the absorbent article. Additionally, a portion of the waist gasketing element is mechanically attached to a portion of the absorbent article. The bio-based content of the absorbent article is from about 5% to about 100% using ASTM D6866-10, method B.

An absorbent article for personal hygiene comprising a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core and a fibrous layer. The absorbent core comprises a core wrap and an absorbent material with superabsorbent polymers. The core wrap comprises a top side and a bottom side bonded to one other through one or more areas substantially free of absorbent material. The fibrous layer is at least partially bonded to one of the sides of the core wrap in the area substantially free of absorbent material. When the absorbent material swells, the core wrap forms one or more channels along the area substantially free of absorbent material. The formation of the channel in the absorbent core causes the formation of one or more corresponding ditches in the fibrous layer.

Absorbent article and absorbent core forming channels when wet

An absorbent structure comprising a planar substrate, an auxiliary glue applied on the substrate, an absorbent material comprising from 80% to 100% by weight of superabsorbent particles deposited on the substrate on an absorbent material deposition area comprising a pattern of absorbent material land areas separated by absorbent material-free junction areas, wherein the deposition area can be notionally divided in eight deposition zones of equal length along the longitudinal direction. A fibrous thermoplastic adhesive layer immobilizes at least some of the absorbent material. The absorbent material is profiled along the longitudinal direction so that at least one of the eight deposition zones is a zone of lower absorbent material amount and the auxiliary glue is absent, or present at a level of at least 50% by weight lower than the average amount of auxiliary glue in at least one of these zones of lower absorbent material amount.

Absorbent structures and cores with efficient immobilization of absorbent material

Substantially planar absorbent core comprising at least 80% and up to 100% by weight of superabsorbent polymer as absorbent material on an absorbent material deposition area and a core wrap. The absorbent material deposition area comprises at least one absorbent material-free channel-forming areas through which the top and bottom substrates of the core wrap are bonded together. An auxiliary glue is applied directly at least to the inner surface of the first substrate on an auxiliary glue application area. The auxiliary glue application area is smaller than the absorbent material deposition area and the core comprises at least one C-wrap seal along at least one edge, in particular along the two longitudinally extending edges of the core.

Absorbent cores having channel-forming areas and C-wrap seals

A disposable diaper is disclosed. The diaper includes a colored topsheet. The topsheet has a basis weight of from 12 to 18 gsm and comprises a plurality of bonded points. Each of the bonded points has a surface area of from 2 mmto 5 mmand the cumulated surface area of the plurality of bonded points is from 10 to 25% of the total surface area of the topsheet.
