Abstract

A material web having a film layer and a nonwoven layer, along with methods of making the material web, are described. The material web has a plurality of micro-deformations and a plurality of macro-deformations, each of the macro-deformations having a distal end, wherein a first portion of macro-deformations has an open or partially open distal end and wherein a second portion of macro-deformations has distal ends which are configured differently than the distal ends of the first portion, and wherein the material web forms a portion of the topsheet.

Claims (17)

1. An absorbent article having a longitudinal axis and a transverse axis which is generally perpendicular to the longitudinal axis, the absorbent article further comprising:

a topsheet;

a backsheet; and

an absorbent system disposed between the topsheet and the backsheet,

wherein the topsheet comprises a material web comprising a film layer and a nonwoven layer, the material web comprising a surface, a plurality of vacuum-formed micro-apertures having an average open area, and a plurality of macro-deformations formed via mechanical deformation, wherein each of the plurality of macro-deformations comprises a sidewall extending in a Z-direction away from the surface and a distal end, wherein the distal end is partially open such that a portion of the distal end comprises a first subplurality of the micro-apertures, wherein the sidewall comprises a second subplurality of the micro-apertures that have been expanded but not ruptured via stretching, and wherein one of the first subplurality of micro-apertures and the second subplurality of micro-apertures has a larger average open area than the other subplurality of micro-apertures.

2. The absorbent article of claim 1 , wherein the film layer forms a portion of a wearer-facing surface of the absorbent article.

3. The absorbent article of claim 1 , wherein the nonwoven layer forms a portion of a wearer-facing surface of the absorbent article.

4. The absorbent article of claim 1 , wherein the absorbent article further comprises a first zone centrally disposed along the longitudinal axis, and a second and third zone flanking the first zone, wherein the plurality of macro-deformations is located in the first zone.

5. The absorbent article of claim 1 , wherein the material web is a composite.

6. The absorbent article of claim 1 , wherein the material web is a laminate.

7. The absorbent article of claim 1 , wherein the distal end has an open area, wherein the open area is less than about 90 percent.

8. The absorbent article of claim 1 , wherein the distal end has an open area, wherein the open area is less than about 75 percent.

9. An absorbent article having a longitudinal axis and a transverse axis which is generally perpendicular to the longitudinal axis, the absorbent article further comprising:

a topsheet;

a backsheet; and

an absorbent system disposed between the topsheet and the backsheet,

wherein the topsheet comprises a material web comprising a film layer and a nonwoven layer, the material web comprising a surface, wherein the topsheet comprises a first zone and a second zone wherein each of the first zone and the second zone comprise a plurality of micro-apertures and wherein the second zone comprises a plurality of macro-deformations comprising a sidewall extending in a Z-direction away from the surface and a distal end, wherein the distal end is partially open such that a portion of the distal end comprises a first subplurality of the micro-apertures, wherein the sidewall comprises a second subplurality of the micro-apertures that have been expanded by stretching, and wherein one of the first subplurality of micro-apertures and the second subplurality of micro-apertures has a larger average open area than the other subplurality of micro-apertures.
