  • Patent number: 10993857
    Abstract: An absorbent article comprises a layered structure with an absorbent material sandwiched between at least two layers of the structure, and at least one elongate tab. Each elongate tab comprises an attached portion by which the tab is attached to a first layer of the layered structure and a fastening portion provided for releasably engaging a landing zone on the absorbent article. Each tab is made of a predetermined material which is deformable by an energy source. The attached portion comprises a plurality of surface protrusions integrally formed of said material, each of said surface protrusions comprising a base portion and a head portion above the base portion. The attached portion is attached to said layer by deformed head portions of at least some of said surface protrusions. In a method for manufacturing such article, the attachment involves deforming head portions of the surface protrusions.
