Abstract

Abstract In accordance with the present invention, a sanitary napkin having a body surface and a garment surface and being comprised of an absorbent means underlayed by a liquid barrier means, wherein the sanitary napkin is relatively highly flexible and has a capacity great enough to handle medium to high menstrual flows, is provided. In a preferred embodiment, the sanitary napkin comprises, from the body surface down, an apertured formed film topsheet, an apertured nonwoven wipe acquisition sheet, a wet-laid tissue, a superabsorbent core, and a barrier sheet. Preferably, the central width of the absorbents is at least about 6.5 centimeters and the caliper of the napkin as a whole is less than about 2.6 millimeters. In a preferred embodiment, the napkin has laterally extending flaps which drape over the edges of the wearer's panties in the crotch and are attachable to the garment side of the wearer's panties.
