Abstract
An absorbent article comprising a hotmelt adhesive comprising a styrene-block-copolymer (SBC), an amorphous polyolefin and optionally a tackifier. The SBC is preferably selected from the group of SEBS, SEPS and SEP polymers, and the amorphous polyolefin is preferably a propylene-based copolymer (PbP) having a weight-average molecular weight Mw of less than 10 000 g/mol. The hotmelt adhesive bonds two components of the article, for example SAP particles on the core wrap.
Claims19
An absorbent article for personal hygiene comprising a hotmelt adhesive, wherein the hotmelt adhesive comprises
- from 20% to 45% by weight of the hotmelt adhesive of at least one styrene-block-copolymer (SBC) and
- from 10% to 60% by weight of the hotmelt adhesive of at least one amorphous polyolefin having an enthalpy of fusion of less than 10 J/g,
- wherein the hotmelt adhesive does not comprise any polyolefin having an enthalpy of fusion greater than 10 J/g,
- wherein enthalpy of fusion is measured in accordance with ISO 11357-2 (2013).
