Hydro-formed film with three-dimensional micro-apertures
View Patent ↗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.
1. A hydro-formed film comprising:
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, each of the plurality of three-dimensional micro-apertures has an apex, and an opening at the apex having a circumference defined, at least in part, by a plurality of irregularly shaped petals, the plurality of three-dimensional micro-apertures having a mesh count in a range of about 40 to about 75 micro-apertures per linear inch,
wherein the hydro-formed film has a Compression Sensor Point (CSP) count of at least about 80.
2. The hydro-formed film according to claim 1 , wherein each of the plurality of three-dimensional micro-apertures has 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.
3. The hydro-formed film according to claim 2 , wherein the protrusion axis ratio is in a range of about 0.9 to 1.1.
4. The hydro-formed film according to claim 1 , wherein the plurality of three-dimensional micro-apertures is arranged in a two dimensional pattern having three-dimensional micro-apertures aligned in a transverse direction of the hydro-formed film and staggered in a machine direction of the hydro-formed film.
5. The hydro-formed film according to claim 1 , wherein the hydro-formed film has an open area of about 25%.
