Abstract

A tissue product having a combination of substantially equal tensile energy absorbed (TEA) in the machine direction and the cross-machine direction of the tissue sheet and a significant level of stretch in both directions provides improved perception of strength and resistance to “poke through” in use.

Claims (30)

1. A tissue sheet having a three-dimensional surface topography, an MD/CD TEA ratio of from about 0.8 to about 1.2 and a CD stretch of about 5 percent or greater.

2. The tissue of claim 1 wherein the MD/CD TEA ratio is from about 0.9 to about 1.1.

3. The tissue sheet of claim 1 having a geometric mean tensile strength of from about 500 to about 1500 grams per 3 inches of width.

4. The tissue sheet of claim 1 having a geometric mean tensile strength of from about 550 to about 1200 grams per 3 inches of width.

5. The tissue sheet of claim 1 having a geometric mean tensile strength of from about 600 to about 1000 grams per 3 inches of width.

6. The tissue sheet of claim 1 having a geometric mean tensile strength of from about 600 to about 900 grams per 3 inches of width.

7. The tissue sheet of claim 1 having a GM TEA of from 2 to about 10 gram-centimeters per square centimeter.

8. The tissue sheet of claim 1 having a GM TEA of from about 2 to about 8 gram-centimeters per square centimeter.

9. The tissue sheet of claim 1 having a GM TEA of from about 2 to about 5 gram-centimeters per square centimeter.

10. The tissue sheet of claim 1 having a GM TEA of from about 2 to about 4 gram-centimeters per square centimeter.

11. The tissue sheet of claim 1 having an MD stretch of about 3 percent or greater.

12. The tissue sheet of claim 1 having an MD stretch of about 5 percent or greater.

13. The tissue sheet of claim 1 having an MD stretch of from about 3 to about 30 percent.

14. The tissue sheet of claim 1 having an MD stretch of from about 3 to about 25 percent.

15. The tissue sheet of claim 1 having an MD stretch of from about 3 to about 15 percent.

16. The tissue sheet of claim 1 having an MD stretch of from about 3 to about 10 percent.

17. The tissue sheet of claim 1 wherein the CD stretch is from about 5 to about 20 percent.

18. The tissue sheet of claim 1 wherein the CD stretch is from about 5 to about 15 percent.

19. The tissue sheet of claim 1 wherein the CD stretch is from about 5 to about 10 percent.

20. The tissue sheet of claim 1 having a CD stretch which is greater than the MD stretch.

21. A tissue sheet of claim 1 having a Normalized Burst Strength of from about 20 to about 40 centimeters.

22. The tissue sheet of claim 21 having a Normalized Burst Strength of from about 20 to about 35 centimeters.

23. The tissue sheet of claim 21 having a Normalized Burst Strength of from about 25 to about 35 centimeters.

24. The tissue sheet of claim 21 having a Normalized Burst Strength of from about 25 to about 30 centimeters.

25. A bath tissue sheet having a three-dimensional surface topography, an MD/CD TEA ratio of from about 0.8 to about 1.2, a Normalized Burst Strength of from about 20 to about 40 centimeters, a CD stretch of from about 5 to about 20 percent, an MD stretch of from about 3 to about 30 percent, a GMT of from about 500 to about 1500 grams per 3 inches of width and a GM TEA of from about 2 to about 10 gram-centimeters per square centimeter.

26. The bath tissue sheet of claim 25 having an MD/CD TEA ratio of from about 0.9 to about 1.1.

27. The bath tissue sheet of claim 25 having an MD/CD TEA ratio of about 1.0.

28. The bath tissue sheet of claim 25 having a Normalized Burst Strength of from about 20 to about 35 centimeters.

29. The bath tissue sheet of claim 25 having a Normalized Burst Strength of from about 25 to about 35 centimeters.

30. The bath tissue sheet of claim 25 having a Normalized Burst Strength of from about 250 to about 30 centimeters.
