Abstract

A web of toilet tissue that includes a shaped line of weakness, wherein toilet tissue exhibits a LWP Factor of greater than about 7.

First claim

What is claimed is:

1. A web of toilet tissue comprising a shaped line of weakness wherein the toilet tissue exhibits a Line of Weakness Performance Factor (LWP Factor) of from about 7 to about 30, and a Full Sheet Average Trapezoidal Tear Strength of less than about 20 g according to the Full Sheet Average Trapezoidal Tear Force Test Method; and wherein the web of toilet tissue is in the form of a roll and wherein the roll exhibits a roll compressibility of less than about 15%.

2. The web of claim 1 , wherein the toilet tissue exhibits a LWP Factor of greater than about 10.

3. The web of claim 1 , wherein the toilet tissue exhibits a LWP Factor of between about 10 and about 20.

4. The web of claim 1 , wherein the toilet tissue exhibits 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.

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

6. The web of claim 1 , wherein the toilet tissue is a through-dried fibrous structure.

7. The web of claim 1 , wherein the toilet tissue is an uncreped fibrous structure.

8. The web of claim 1 , wherein the shaped line of weakness has a wavelength of from about 0.75 inches to about 2.5 inches and an amplitude of from about 0.1 inches to about 1 inch.

9. The web of claim 1 , wherein the web comprises a CD elongation of greater than about 8% according to the Dry Tensile Strength Test Method.

10. A web of sanitary tissue product comprising a shaped line of weakness-wherein the sanitary tissue product exhibits a Line of Weakness Performance Factor (LWP Factor) of greater than about 7, and a Full Sheet Average Trapezoidal Tear Strength of less than about 18 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method; and wherein the web of sanitary tissue product is in the form of a roll and wherein the roll exhibits a roll compressibility of less than about 12.5%.

11. The web of claim 10 , wherein the sanitary tissue product exhibits a LWP Factor of greater than about 10.

12. The web of claim 10 , wherein the sanitary tissue product exhibits a LWP Factor of between about 10 and about 20.

13. The web of claim 10 , wherein the sanitary tissue product exhibits 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.

14. The web of claim 10 , wherein the sanitary tissue product exhibits a Dry Burst of between about 100 g and about 1000 g, as measured according to the Dry Burst Test Method.

15. The web of claim 10 , wherein the sanitary tissue product exhibits a Full Sheet Tensile Strength of between about 400 g and about 850 g, as measured by the Full Sheet Tensile Strength Test Method.

16. The web of claim 10 , wherein the web comprises a CD elongation of greater than about 10% according to the Dry Tensile Strength Test Method.

17. A roll of sanitary tissue product formed by a web comprising a shaped line of weakness wherein the web exhibits a Line of Weakness Performance Factor (LWP Factor) of from about 7 to about 30; wherein the web comprises a CD elongation of greater than about 14% according to the Dry Tensile Strength Test Method and a Full Sheet Average Trapezoidal Tear Strength of less than about 16 g according to the Full Sheet Average Trapezoidal Tear Force Test Method; and wherein the roll exhibits a roll compressibility of less than about 10%.

18. The roll of claim 17 , wherein the roll of sanitary tissue product exhibits a roll compressibility of from about 4% to about 7%.

19. The roll of claim 17 , wherein the toilet tissue exhibits a LWP Factor of between about 10 and about 20.

20. The roll of claim 17 , 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.

21. The roll of claim 17 , wherein the sanitary tissue is a through-dried fibrous structure.

22. The roll of claim 17 , wherein the sanitary tissue product exhibits 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.

23. The roll of claim 17 , wherein the sanitary tissue exhibits a Geometric Mean Peak Elongation of greater than about 15%, as measured according to the Dry Tensile Strength Test Method.

24. The web of claim 17 , wherein the roll exhibits a roll compressibility of less than about 8%.
