A composite material comprises an elastomeric three-dimensional, apertured film having a planar surface and a three-dimensional surface and a carrier material bonded to at least the planar surface. Also claimed are: (1) an absorbent article comprising a top-sheet formed of the composite material, an absorbent pad and a fluid impervious back-sheet; and (2) a process for the manufacture of the composite material comprising: (a) supplying successive portions of a molten or semi-molten elastomeric film having a top surface and a bottom surface, the film being supplied at a predetermined temperature; (b) supplying a carrier material onto the top surface of the elastomeric film; (c) optionally providing a compressive force to the film and the carrier material; (d) subjecting the bottom surface of the elastomeric film to the action of a fluid pressure differential; and (e) maintaining the pressure differential for a period of time to form a plurality of three-dimensional apertured structures in the elastomeric film and to bond it to form the breathable, elastomeric composite material. |
