Absorbent article with high toughness adhesive

A package comprising an interior space and an exterior surface may have a plurality of disposable absorbent articles disposed within the interior space of the package. Each of the disposable absorbent articles may have a topsheet; a backsheet; an absorbent core located between the topsheet and the backsheet. The absorbent products may exhibit an In-Bag Stack Height of less about 80 mm as measured according to an In-Bag Stack Height Test.

Absorbent products having improved packaging efficiency

Bleached polyacrylic acid crosslinked cellulose fibers with reduced furfural content are disclosed. The reduced furfural content is accompanied by a strong reduction of malodor associated with crosslinked fibers. Methods of furfural reduction include treatment with hydrogen peroxide in the absence of alkaline or other bleaching agents subsequent to curing polyacrylic acid crosslinked cellulose fibers. Some embodiments of treated polyacrylic acid crosslinked cellulose fibers have a furfural content lower than 1.3 ppm. In some embodiments, the reduction of furfural content of the treated crosslinked fibers compared to untreated crosslinked fibers is at least 55%. in some embodiments, furfural content decreases with aging of the treated crosslinked fibers.
