An apertured formed film web with a first and second surface that is suitable for use as a topsheet of an absorbent article has been patented. The web consists of a first and second layer with both layers comprising a hydrophilic block copolymer of a polyether and another polymer selected from a group consisting of polyester, polyamide and polyurethane. The other first and second layers comprise a polymeric hydrophobic layer and form a film web containing a plurality of micro- and macro-apertures having the hydrophilic block copolymers on inside surfaces of the apertures and the apertures form a plurality of fluid passage ways placing the first and second surfaces in fluid communication with one another.
