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.
Claims20
A disposable absorbent article comprising:
- a top sheet,
- an acquisition distribution layer, and
- a hot melt adhesive composition comprising,
- an olefin polymer, and
- from 5% by weight to 60% by weight of a high softening point hydrocarbon tackifying agent having a softening point of from 110° C. to 150° C.,
- wherein the hot melt adhesive composition adheres the top sheet to the acquisition distribution layer.
3 more elements
A hot melt adhesive composition comprising:
- a.) from 22% by weight to 55% by weight of a single site catalyzed propylene based polymer that has a co-monomer content of from 0% by weight to 20% by weight and a Brookfield Viscosity at 190° C. of no greater than 25,000;
- b.) from 20% by weight to 55% by weight of a high softening point hydrocarbon tackifying agent, that is at least partially hydrogenated, having a softening point of from around 110° C. to around 150° C.;
- and
- c.) from 3% by weight to 35% by weight of plasticizer.
