  • Patent number: 11242470
    Abstract: The invention includes a hot melt adhesive composition including an olefin polymer and a high melt point hydrocarbon tackifying agent, such compositions unexpectedly provide improved bonding between the layers found in a disposable absorbent article. In particular, such compositions improve the bond between the nonwoven top sheet and the acquisition distribution layer.
