    Abstract: An apertured, film-coated nonwoven fabric or material and a process for making the film-coated nonwoven fabric or material are provided. A nonwoven material layer is formed and extrusion coated with a polymer film to form a film-coated nonwoven material, the film-coated nonwoven material including a film layer having a thickness not greater than about 0.30 mils. A plurality of apertures may be formed in at least the film layer to form the apertured, film-coated nonwoven material.
