Abstract

A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article may include a first waist region, a second waist region, a crotch region disposed between the first and second waist regions; a first waist edge and a second waist edge; and a first longitudinal edge and a second longitudinal edge. The disposable absorbent article may include a chassis comprising a topsheet, a backsheet comprising a polymeric film, an absorbent core disposed between the topsheet and the backsheet. The polymeric film may be at least 20 mm more narrow than the chassis. An opacity strengthening patch may be disposed on the backsheet.

Claims

1. A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article comprising:

a first waist region, a second waist region, a crotch region disposed between the first and second waist regions;

a first waist edge and a second waist edge; and

a first longitudinal edge and a second longitudinal edge, the disposable absorbent article comprising a chassis comprising;

1.) a topsheet;

2.) a backsheet comprising a polymeric film;

3.) an absorbent core disposed between the topsheet and the backsheet;

wherein the polymeric film is at least 20 mm more narrow than the chassis;

wherein an opacity strengthening patch is disposed on the backsheet.

2. The disposable absorbent article of claim 1, wherein the polymeric film is less than about 50 mm wider than the absorbent core.

3. The disposable absorbent article of claim 1, wherein the polymeric film is less than about 30 mm wider than the absorbent core.

4. The disposable absorbent article of claim 1, wherein the polymeric film is at least about 60 mm more narrow than the chassis width.

5. The disposable absorbent article of claim 1, wherein the polymeric film is at least about 100 mm more narrow than the chassis width.

6. The disposable absorbent article of claim 1, wherein the opacity strengthening patch has a basis weight of at least about 13 gsm.

7. The disposable absorbent article of claim 1, wherein the opacity strengthening patch has tensile properties of about 0.4N/25 mm, when strained at 2% engineering strain.

8. The disposable absorbent article of claim 1, further comprising a leg gasketing system, wherein the leg gasketing system comprises an inner cuff and an outer cuff;

wherein the inner cuff comprises an inner cuff folded edge and an inner cuff material edge;

wherein the outer cuff comprises an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff material edge, wherein the leg cuff extends from the first waist edge to the second waist edge and is joined to the topsheet and/or backsheet between the inner cuff folded edge and the outer cuff folded edge in the crotch region.

9. The disposable absorbent article of claim 8, wherein the leg gasketing system does not comprise a polymeric film.

10. The disposable absorbent article of claim 8, wherein the opacity strengthening patch is disposed between the backsheet and the leg gasketing system in at least one of the first and second waist regions.

11. The disposable absorbent article of claim 8, wherein the opacity strengthening patch extends to the lateral edge of the article and overlaps at least one of the leg gasketing system or the polymer film.

12. The disposable absorbent article of claim 8, wherein the opacity strengthening patch overlaps the leg gasketing system by less than about 25 mm.

13. The disposable absorbent article of claim 1, wherein the opacity strengthening patch is disposed on the body facing surface.

14. The disposable absorbent article of claim 1, wherein the opacity strengthening patch is attached by a means selected from the group consisting of glue, mechanical bonds, thermal bonds, and combinations thereof.

15. The disposable absorbent article of claim 1, wherein the absorbent core is substantially cellulose free.

16. The disposable absorbent article of claim 1, wherein the opacity strengthening patch is discrete and is located in the first and second waist regions of the disposable absorbent article.

17. The disposable absorbent article of claim 1, wherein the opacity strengthening patch is continuous and spans the entire length of the disposable absorbent article.

18. The disposable absorbent article of claim 1, wherein the opacity strengthening patch has a hunter color opacity of greater than about 25%.

19. The disposable absorbent article of claim 1, wherein the opacity strengthening patch overlaps the polymeric film layer by less than about 30 mm.

20. The disposable absorbent article of claim 1, wherein there is a gap between the opacity strengthening patch and the polymeric film layer, wherein the gap is less than about 30 mm.
