1. A film comprising:a polymeric web having first and second opposing, substantially planar web surfaces; and
a plurality of three dimensional perforations through the polymeric web, each three dimensional perforation comprising a hollow protrusion extending from the first planar web surface, each protrusion having an apex, an opening at the apex having a circumference defined, at least in part, by a plurality of irregularly shaped petals, and an elliptical cross-section parallel to the planar surface of the web, the elliptical cross-section having a protrusion axis ratio in a range of 0.65 to 1.35,
wherein the plurality of three dimensional perforations were formed using a hydroforming process, and
wherein the localized protrusions are formed in the web in a two-dimensional pattern having a mesh count in a range of about 40 to about 75.
