Abstract

A laminate comprises a first layer comprising a plurality of lower opacity zones positioned within a higher opacity zone is provided. The plurality of lower opacity zones form a first pattern. The laminate comprises a second layer comprising a second pattern. The laminate comprises a non-joined span of the first and second layers having a dimension of at least about 20 mm. A first portion of the second pattern is visible through at least some of the plurality of lower opacity zones when the first layer, within the non-joined span, is in a first position relative to the second layer, within the non-joined span. A second portion of the second pattern is visible through at least some of the plurality of lower opacity zones when the first layer, within the non-joined span, is in a second position relative to the first layer, within the non-joined span.

First claim

What is claimed is:

1 . A laminate comprising:
a first layer comprising a plurality of lower opacity zones positioned within a higher opacity zone, wherein the plurality of lower opacity zones form a first pattern; and a second layer comprising a second pattern; wherein the first layer is intermittently joined to the second layer to form the laminate, wherein the laminate comprises a non-joined span of the first and second layers having a dimension of at least about 20 mm, wherein a first portion of the second pattern is visible through at least some of the plurality of lower opacity zones when the first layer, within the non-joined span, is in a first position relative to the second layer, within the non-joined span, and wherein a second portion of the second pattern is visible through at least some of the plurality of lower opacity zones when the first layer, within the non-joined span, is in a second position relative to the first layer, within the non-joined span.

2 . The laminate of claim 1 , wherein the first layer is moveable relative to the second layer in the non-joined span.

3 . The laminate of claim 1 , wherein the plurality of low opacity zones comprise a plurality of apertures.

4 . The laminate of claim 1 , wherein the first layer has a first path length in the non-joined span, wherein the second layer has a second path length in the non-joined span, and wherein the first and second path lengths are different by at least about 2%.

5 . The laminate of claim 1 , wherein the dimension is in the range of about 20 mm to about 120 mm.

6 . The laminate of claim 1 , wherein the second layer is a non-apertured layer.

7 . The laminate of claim 1 , wherein the second pattern comprises a printed pattern, an embossed pattern, or a patterned adhesive.

8 . The laminate of claim 1 , wherein the first pattern is different than the second pattern.

9 . The laminate of claim 1 , wherein the first layer is intermittently joined to the second layer by a plurality of adhesive or mechanical bonds, and wherein the bonds are spaced at least about 20 mm apart from each other.

10 . The laminate of claim 1 , wherein the adhesive or mechanical bonds are continuous or discontinuous.

11 . The laminate of claim 3 , wherein the plurality of apertures have Interaperture Distances, according to the Aperture Test herein, wherein the Interaperture Distances of the plurality of apertures have a distribution having a mean and a median, and wherein the mean is greater than the median by at least about 4%.

12 . The laminate of claim 3 , wherein the plurality of apertures have an Average Absolute Feret Angle of greater than about 20 degrees, according to the Aperture Test herein.

13 . The laminate of claim 1 , wherein the second pattern in the second layer comprises a plurality of apertures.

14 . The laminate of claim 1 , wherein the second pattern has a different color than the first layer, or wherein the second pattern has a different color than the first layer and the second layer.

15 . An absorbent article comprising the laminate of claim 1 .

16 . The absorbent article of claim 15 , wherein the first layer comprises a garment-facing nonwoven layer, and wherein the second layer comprises a backsheet film.

17 . The absorbent article of claim 15 , wherein the first layer comprises nonwoven layer, and wherein the second layer comprises a film.

18 . The absorbent article of claim 15 , wherein the first layer comprises a nonwoven layer, and wherein the second layer comprises a nonwoven layer.

19 . A package comprising a plurality of the absorbent articles of claim 15 , wherein the package has an In-Bag Stack Height in the range of about 70 mm to about 100 mm, according to the In-Bag Stack Height Test herein.

20 . An absorbent article comprising:
a laminate comprising:
a first nonwoven layer comprising a plurality of lower opacity zones positioned within a higher opacity zone, wherein the plurality of lower opacity zones form a first pattern; and
a second layer comprising a second pattern;
wherein the first layer is intermittently joined to the second layer to form the laminate, wherein the laminate comprises a non-joined span of the first and second layers having a dimension of at least about 20 mm, wherein a first portion of the second pattern is visible through at least some of the plurality of lower opacity zones when the first layer, within the non-joined span, is in a first position relative to the second layer, within the non-joined span, and wherein a second portion of the second pattern is visible through at least some of the plurality of lower opacity zones when the first layer, within the non-joined span, is in a second position relative to the first layer, within the non-joined span.

21 . The absorbent article of claim 20 , wherein the second layer comprises a film, and wherein the first pattern is different than the second pattern.

22 . An absorbent article comprising:
a laminate comprising:
a first nonwoven layer comprising a plurality of apertures in a first pattern; and
a second layer comprising a second, different pattern;
wherein the first layer is intermittently joined to the second layer to form the laminate, wherein the laminate comprises a non-joined span of the first and second layers having a dimension of at least about 30 mm, wherein a first portion of the second pattern is visible through at least some of the plurality of apertures when the first layer, within the non-joined span, is in a first position relative to the second layer, within the non-joined span, and wherein a second portion of the second pattern is visible through at least some of the plurality of apertures when the first layer, within the non-joined span, is in a second position relative to the first layer, within the non-joined span.
