The present invention relates to an absorbent article comprising a liquid permeable topsheet, a liquid-impermeable backsheet and an absorbent core positioned between the topsheet and the backsheet. The absorbent article comprises pressure sensitive adhesive on a garment facing surface of the backsheet, and the backsheet is a breathable polyolefin-based film and has a Water Vapour Transmission Rate measured according to NWSP 070.4.RO (15) of at least 1000 g/m/24 h, preferably at least 3000 g/m/24 h, and a tear resistance measured according to Elmendorf Tear ASTM D1922 (15) of at least 300 mN.

Absorbent article with breathable backsheet

The present disclosure provides a packaging unit for hygiene articles and a method for forming such a unit. The packaging unit has a first packaging function as a packaging wrap for a non-used article, and a second disposal function as a disposal wrap for a used article. The packaging unit further comprises a user prompting device having a wrap-facing surface and a user-facing surface, wherein the user prompting device is permanently attached to the wrap such that at least a portion of the wrap-facing surface of the user prompting device is in contact with the inner surface of the wrap. The user prompting device is arranged to prompt the user to employ the second disposal function of the packaging unit.

Packaging unit having improved sealing and a user prompting device, and a method for forming such a packaging unit

A packaging unit for hygiene articles, the unit being formed from a sheet of material having an inner surface, said inner surface comprising an edge portion being provided with a resealable adhesive for closure of the packaging unit. The sheet has a longitudinal center line and at least one transversely extending folding axis dividing the sheet into a first region and a second region. A tab is arranged at an edge portion of the first region. The tab extends in a longitudinal direction from said edge portion so that an extension of the tab along or parallel to the center line from a tab base to an outer edge of the tab is 0.5 cm or more. A method of forming the packaging unit is also provided.

Packaging unit for hygiene articles and a method of forming a packaging unit

A packaging unit for hygiene articles that is formed from a sheet of material having an inner surface comprises an edge zone comprising an inner edge portion and an outer edge portion. At least one of the outer and inner edge portions comprises at least one region provided with a resealable adhesive. The sheet has at least one folding axis dividing said sheet into a first and second regions region. The sheet is folded about said at least one folding axis with said first and second regions in an overlapping configuration, thereby providing a packaging unit. Overlapping outer edge portions of the sheet layers are at least partly adhesive-free and are at least partially connected to each other by a mechanical interaction providing a sealing strength of 0.2 to 1.5 N. A method for forming the packaging unit is provided.

A method for forming a wrapping material for hygiene articles involves: providing one of the inner edge portion and the outer edge portion of the edge zone of the first region with a first resealable adhesive, such that the other of the inner edge portion and the outer edge portion of the edge zone of the first region is adhesive-free; providing one of the inner edge portion and the outer edge portion of the edge zone of the second region with a first resealable adhesive, such that the other of the inner edge portion and the outer edge portion of the edge zone of the second region is adhesive-free; and providing at least one of the first central portion of the first region and the second central portion of the second region with a second adhesive; wherein the steps a-c are performed simultaneously.

Method for forming a wrapping sheet having improved sealing

A packaging unit for hygiene articles is formed from a sheet having a folding axis dividing the sheet into first and second regions. One of the inner edge portion and the outer edge portion of the edge zone of the first region is provided with resealable adhesive, thus forming a first adhesive zone. The other of the inner edge portion and the outer edge portion is adhesive-free. The inner edge portion or the outer edge portion of the edge zone of the second region corresponding to the adhesive-carrying edge portion of the first region is adhesive-free, such that when the sheet is folded about the folding axis, the edge portions carrying resealable adhesive in the first region are brought in contact with the adhesive-free edge portions in the second region. A distance between the at least one first folding axis and the first adhesive zone is 1-20 mm.

A nonwoven fabric comprising at least 50% by weight microfibers having a fineness of 1.0 dtex or less and a length of at least 30 mm and having been combined by hydroentangling. The fabric is apertured by said hydroentangling, and has been carded before hydroentangling. The fabric may be used as a topsheet material on an absorbent article.
