Claim:
1. A method for making an apertured polymeric film-based web for use as an absorbent article topsheet, said method comprising the steps of: a. providing a vacuum forming structure comprising a plurality of perforations, a first side and an opposing second side; b. extruding a resinous melt onto the first side of the perforated vacuum forming structure; c. providing a vacuum on the second side of the perforated vacuum forming structure so that portions of the resinous melt are drawn into the plurality of perforations to form a film having a first plurality of apertures having a first diameter and a height extending from a first surface of the film; d. thereafter contacting the film having a first plurality of apertures with needles or heatable pins to define a second plurality of apertures having a second diameter that is greater than the first diameter, wherein discrete needles or pins associated with this step enables the first plurality of apertures in areas not impacted by the discrete needles/pins to remain substantially unaltered relative to their as-made state; e. wherein the first surface of the film defines a wearer-contacting surface of the web, and wherein the first surface of the film is hydrophilic; f. wherein sidewalls of the second plurality of apertures extend in a direction away from the wearer-contacting surface.
