a composite substrate for use as a coversheet on disposable articles such as disposable diapers , sanitary napkins , disposable bed pads , nursing pads , finger dressings , and incontinent diapers , or the like . the cover sheet comprises an inner layer of polyethylene thermoplastic film secured to and between the inner surfaces of a top layer and a bottom layer of nonwoven polypropylene fibrous webs , by means of a pair of , one of which being a heated embossed roll applied to at least one of the outer surfaces of the fibrous web . the heat from the heated roll causes the film to melt in discrete areas forming apertures therein without substantially affecting the fibrous webs . as the film melts , it contacts fibers in the substantially unaffected adjacent fibrous web layers , causing the film and webs to be secured to each other at least at the peripheral edges of the discrete apertured areas , leaving a matrix of fibers covering the apertured areas .
