Abstract
The invention includes a hot melt adhesive composition including 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; and a non-hydrogenated C5 tackifying agent having a softening point of from 98° C. to around 130° C. The adhesive composition has been found to give a good balance of static peel strength and dynamic peel strength when used as a construction adhesive in a disposable absorbent article.
Claims18
A hot melt adhesive composition comprising:
- a.) 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;
- and
- b.) a non-hydrogenated high softening point C5 tackifying agent having a softening point of from 98° C. to around 130° C.
A disposable absorbent article comprising:
- a.) a body fluid impermeable back sheet,
- b.) a nonwoven top sheet, and
- c.) a hot melt adhesive composition comprising:
- i. 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;
- and
- ii. a non-hydrogenated high softening point C5 tackifying agent having a softening point of from 98° C. to around 130° C.
- wherein the body fluid impermeable back sheet is adhered to the nonwoven top sheet through the hot melt adhesive composition.
