Abstract

A structured rolled sanitary tissue product having at least two plies, wherein the structured rolled sanitary tissue product has a crumple resistance of less than 30 grams force, a caliper of at least 450 microns/ply, and a bulk softness (TS7) of 10 or less.

Claims (15)

1. A structured rolled sanitary tissue product comprising at least two plies, wherein the structured rolled sanitary tissue product has a crumple resistance of less than 30 grams force, a caliper of at least 450 microns/2 ply, and a bulk softness (TS7) of 10 or less.

2. The structured rolled sanitary tissue product according to claim 1 , wherein the structured rolled sanitary tissue product has an average peak to valley depth of at least 100 microns.

3. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a caliper of 450 microns/2 ply to 600 microns/2 ply and is un-calendered.

4. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a caliper of 600 microns/2 ply to 800 microns/2 ply and is uncalendered.

5. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a caliper of 500 microns/2 ply to 700 microns/2 ply and is calendered.

6. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a basis weight in g/m 2 per 2 ply of 28 g/m 2 to 39 g/m 2 .

7. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a machine direction tensile strength per 2 ply of 110 N/m to 190 N/m.

8. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a cross machine direction tensile strength per 2 ply of 35 N/m to 90 N/m.

9. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a machine direction stretch of 4% to 30% per 2 ply.

10. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a cross direction stretch of 4% to 20% per 2 ply.

11. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a 2-ply cross direction wet tensile strength of 0 to 25 N/m.

12. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a ball burst strength of 150 gf to 300 gf per 2-ply.

13. The structured rolled sanitary tissue product of claim 1 , wherein the structured rolled sanitary tissue product has a lint value of 2.5 to 7.5 per 2 ply.

14. The structured rolled sanitary product of claim 1 , wherein the structured rolled sanitary tissue product has a softness of 85 TSA to 100 TSA.

15. The structured rolled sanitary product of claim 1 , wherein the structured rolled sanitary tissue product has a bulk softness (TS7) of from 8 to 10.
