ABSTRACT:
A composite cover material for absorbent articles and the like and a method for making the same are disclosed herein. The cover material is made of a thermoplastic film in contact with an external layer of nonwoven material. Selective point application of heat and pressure to the external surface of the nonwoven material causes the formation of a plurality of densified and partially fused areas in the nonwoven which are in vertical alignment with a corresponding plurality of concurrently formed perforations in the film. The densified and fused areas in the nonwoven act to mask the perforations in the film and in addition, restrict fluid flow when the cover material is under compression by partially blocking the performations in the film.
