Abstract
An absorbent personal hygiene article including a topsheet. The topsheet includes a film layer, wherein the film layer includes a pattern of cones and valleys. The cones may project upwardly from adjacent valleys to rim edges proximate an upper side of the film layer. The cones circumscribe and define apertures through the film layer. The film layer may be disposed on a fluid management layer or an absorbent core layer.
Claims23
An absorbent personal hygiene article comprising:
- a topsheet, the topsheet comprising a film layer, wherein the film layer comprises polyethylene (PE), wherein the polyethylene is a homogeneous blend of low density polyethylene (LDPE) and linear low-density polyethylene (LLDPE), wherein the homogeneous blend is at least 50% by weight LDPE, and LLDPE;
- wherein the film layer has a basis weight of from about 14 gsm to about 24 gsm,
- wherein the film layer comprises a pattern of cones and valleys, the cones projecting upwardly from adjacent valleys to rim edges proximate an upper side of the film layer, wherein the cones circumscribe and define apertures through the film layer, wherein the aperture is formed at rim edge of the cone, wherein the apertures have an average largest x-y dimension (ar) of about 375 μm to about 550 μm, wherein the cones have an average height (ch) of about 300 μm to about 500 μm, wherein the apertures have a numerical density of about 140 to about 500 apertures per cm2 x-y plane surface area of the film layer.
