Hydro-formed film with three-dimensional micro-apertures

A hydro-formed film includes a polymeric web having a first substantially planar surface and a second substantially planar surface opposite the first substantially planar surface, and a plurality of three-dimensional micro-apertures extending from the first substantially planar surface. The plurality of three-dimensional micro-apertures have a mesh count in a range of about 40 to about 75 apertures per linear inch. The hydro-formed film has a Compression Sensor Point (CSP) count of at least about 80.

Method and apparatus for making an apertured web

A method of creating a topsheet for an absorbent article is disclosed. The method includes the steps of: obtaining a pre-cursor web of material, the pre-cursor web of material having a first surface and an opposing second surface, wherein the pre-cursor web of material is a composite or laminate web having a first layer and a second layer, wherein the first layer is a film and the second layer is a nonwoven material having a plurality of fibers; forming a first plurality of apertures having sidewalls extending in a first direction from the pre-cursor web of material; forming a second plurality of apertures having sidewalls extending in a second direction from the pre-cursor material, wherein the first direction and the second direction are different; and forming a plurality of embossments in the pre-cursor web of material, wherein the embossments are oriented in a third direction opposite the first direction.
