Abstract
An absorbent article, such as a thin incontinence pad or pantyliner, is disclosed which has an absorbent core formed from multiple layers of blended material for providing protection against involuntary urine loss. A method of forming the absorbent article is also disclosed. The absorbent article includes a liquid permeable bodyside liner, a liquid-impermeable baffle, and first and second absorbents positioned between the liner and the baffle. The first absorbent is a stabilized material containing a superabsorbent and has a predetermined basis weight. The second absorbent is also a stabilized material containing a superabsorbent. The second absorbent is positioned below the first absorbent and has a basis weight that is at least equal to the basis weight of the first absorbent.
