ABSTRACT:
An absorbent article structure is provided comprising a permeable, internal layer (10), an intermediate absorbent layer (20) and a liquid-impervious, outer layer (30). Outer layer (30) comprises an inherently-porous paper length (32) impregnated with a selective adhesive forming a liquid-impervious and air-permeable coat (34), which only adheres to itself. A disposable diaper (50) can be manufactured with the structure, being entirely degradable and eliminating the "greenhouse" effect of traditional diapers having an outer plastic layer. The self-sticking properties of the coat (34) eliminate the need for tapes and tabs on the diaper.
