Abstract

A roll of sanitary tissue product that includes a shaped line of weakness, wherein the roll of sanitary tissue product exhibits a roll compressibility of from about 2% to about 10%, and the sanitary tissue product has a Full Sheet Average Trapezoidal Tear Strength of about 8 g to about 20 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method.

First claim

What is claimed is:

1. A roll of sanitary tissue product comprising a shaped line of weakness such that the line of weakness is nonlinear, wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 5%, and the sanitary tissue product has a Full Sheet Average Trapezoidal Tear Strength of about 8 g to about 20 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method.

2. The roll of claim 1 , wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 4%.

3. The roll of claim 1 , wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 3%.

4. The roll of claim 1 , wherein the sanitary tissue product exhibits a Full Sheet Average Trapezoidal Tear Strength of about 10 g to about 18 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method.

5. The roll of claim 1 , wherein the sanitary tissue product exhibits a Full Sheet Average Trapezoidal Tear Strength of about 11 g to about 17 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method.

6. The roll of claim 1 , wherein the sanitary tissue exhibits a Dry Burst of between about 100 g and about 1000 g, as measured according to the Dry Burst Test Method.

7. The roll of claim 1 , wherein the sanitary tissue is a through-dried fibrous structure.

8. The roll of claim 1 , wherein the sanitary tissue is an uncreped fibrous structure.

9. A roll of sanitary tissue product comprising a shaped line of weakness such that the line of weakness is nonlinear, wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 4%, and the sanitary tissue product has a Full Sheet Average Trapezoidal Tear Strength of about 8 g to about 20 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method, and a Basis Weight of from about 30 g/m 2 to about 90 g/m 2 , as measured according to the Basis Weight Test Method.

10. The roll of claim 9 , wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 3%.

11. The roll of claim 9 , wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 2.5%.

12. The roll of claim 9 , wherein the sanitary tissue exhibits a Dry Burst of between about 100 g and about 1000 g, as measured according to the Dry Burst Test Method.

13. The roll of claim 9 , wherein the sanitary tissue is a through-dried fibrous structure.

14. The roll of claim 9 , wherein the sanitary tissue is an uncreped fibrous structure.

15. A roll of sanitary tissue product comprising a shaped line of weakness such that the line of weakness is nonlinear, wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 3%, and the sanitary tissue product has a Full Sheet Average Trapezoidal Tear Strength of about 8 g to about 20 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method, and a Geometric Mean Peak Elongation of greater than about 15%, as measured according to the Dry Tensile Strength Test Method.

16. The roll of claim 15 , wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 2.8%.

17. The roll of claim 15 , wherein the roll of sanitary tissue product exhibits a roll compressibility of less than about 2.4%.

18. The roll of claim 15 , wherein the sanitary tissue exhibits a Dry Burst of between about 100 g and about 1000 g, as measured according to the Dry Burst Test Method.

19. The roll of claim 15 , wherein the sanitary tissue is a through-dried fibrous structure.

20. The roll of claim 15 , wherein the sanitary tissue is an uncreped fibrous structure.
