Abstract
A disposable absorbent article having a breathable fluid impervious backsheet. The disposable absorbent article preferably includes a fluid pervious topsheet, a breathable, fluid impervious backsheet secured to the topsheet, and an absorbent core disposed between the topsheet and the backsheet. The breathable, fluid impervious backsheet exhibits substantially zero dynamic fluid transmission when subjected to an impact energy of about 1000 joules/m.sup.2, and exhibits a mass vapor transmission rate of at least about 2000 g/m.sup.2 /24 hr.
Claims29
