Abstract

A tissue sheet having a deep discontinuous pocket structure provides improved durability as measured by the ratio of the cross-machine direction tensile energy absorbed to the cross-machine direction tensile strength.

Claims (17)

1. A tissue sheet having a deep discontinuous pocket structure, said tissue sheet having a CD TEA/CD tensile strength ratio of about 0.070 or greater and a CD stretch of about 5 percent or greater.

2. The tissue sheet of claim 1 wherein the CD TEA/CD tensile strength ratio is from about 0.070 to about 0.100.

3. The tissue sheet of claim 1 wherein the CD TEA/CD tensile strength ratio is from about 0.070 to about 0.090.

4. The tissue sheet of claim 1 wherein the CD TEA/CD tensile strength ratio is from about 0.075 to about 0.085.

5. The tissue sheet of claim 1 having a CD slope/CD tensile strength ratio of about 0.007 or greater.

6. The tissue sheet of claim 1 having a CD slope/CD tensile strength ratio of from about 0.007 to about 0.015.

7. The tissue sheet of claim 1 having a CD slope/CD tensile strength ratio of from about 0.007 to about 0.011.

8. The tissue sheet of claim 1 having a CD slope/CD tensile strength ratio of from about 0.009 to about 0.011.

9. The tissue sheet of claim 1 having a bulk of about 23 cubic centimeters or greater per gram.

10. The tissue sheet of claim 1 having a bulk of from about 23 to about 40 cubic centimeters per gram.

11. The tissue sheet of claim 1 having a bulk of from about 25 to about 30 cubic centimeters per gram.

12. The tissue sheet of claim 1 having a Pinhole Coverage Index of about 0.25 or lees.

13. The tissue sheet of claim 1 having a Pinhole Count Index of about 65 or less.

14. The tissue sheet of claim 1 having a Pinhole Size index of about 600 or less.

15. The tissue sheet of claim 1 having a CD stretch of about 10 percent or greater.

16. The tissue sheet of claim 1 having a CD stretch of from about 5 to about 15 percent.

17. The tissue sheet of claim 1 having a CD stretch of from about 8 to about 13 percent.
