Abstract: Films and methods for cutting or perforating webs including films are disclosed. The films can include a polymer and a plurality of particles. The plurality of particles can include absorbent filler particles and void generating filler particles. The absorbent filler particles can provide between about 1% to about 40% by weight of the film. The void generating filler particles can provide between about 10% to about 40% by weight of the film. The absorbent filler particles can be a different particle than the void generating particles. The film can also include a plurality of voids.

Abstract: Methods and apparatuses for producing a zoned and/or layered substrate are described. A method can include providing a first supply of fibers, providing a second supply of fibers, and providing a headbox. The headbox can include a machine direction, a cross-direction, and a first cross-directional divider that separates a first zone of the headbox from a second zone of the headbox in a cross-directional manner. The method can further include transferring the first supply of fibers and the second supply of fibers to the headbox. The method can also include transferring the first supply of fibers and the second supply of fibers through the headbox to provide the substrate.

Abstract: An absorbent article having a fluid-handling system includes a fluid permeable bodyside liner; a fluid impermeable outer cover; an absorbent core disposed between the liner and the outer cover, wherein the absorbent core includes superabsorbent material and optionally fluff pulp; and a core wrap at least partially encircling the absorbent core, wherein the core wrap includes a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material. Fibers of the nonwoven material are entirely cellulose fibers, and the core wrap includes opposing core wrap surfaces each having a textured surface. Each surface includes an average material plane, a plurality of ridges extending in a z-direction from the average material plane, and a plurality of grooves alternating with the plurality of ridges, wherein the grooves depth extend in the opposite z-direction from the average material plane.
