Abstract

A web of sanitary tissue of the present disclosure may comprise 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 between about 8 g and about 20 g according to the Full Sheet Average Trapezoidal Tear Force Test Method.

Claims (20)

1. A web of sanitary tissue comprising a shaped line of weakness, wherein the web of sanitary 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 between about 8 g and about 20 g according to the Full Sheet Average Trapezoidal Tear Force Test Method.

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

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

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

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

8. 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 from about 7 to about 30, and a Full Sheet Average Trapezoidal Tear Strength of between about 8 g and about 20 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method, and an average Free Fiber End value of greater than about 1.5.

9. The web of claim 8 , wherein the sanitary tissue product exhibits a LWP Factor of greater than about 10.

10. The web of claim 8 , wherein the sanitary tissue product exhibits a LWP Factor of between about 10 and about 20.

11. The web of claim 8 , 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.

12. The web of claim 8 , 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.

13. The web of claim 8 , 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.

14. A roll of sanitary tissue product comprising a shaped line of weakness having an amplitude of from about 0.1 inches to about 1 inch, wherein the roll of sanitary tissue product exhibits a roll compressibility of from about 2% to about 10%, and the sanitary tissue product and a Line of Weakness Performance Factor (LWP Factor) of from about 7 to about 30, and a Full Sheet Average Trapezoidal Tear Strength of between about 8 g and about 20 g according to the Full Sheet Average Trapezoidal Tear Force Test Method.

15. The roll of claim 14 , wherein the roll of sanitary tissue product exhibits a roll compressibility of from about 4% to about 7%.

16. The roll of claim 14 , wherein the toilet tissue exhibits a LWP Factor of between about 10 and about 20.

17. The roll of claim 14 , 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.

18. The roll of claim 14 , wherein the sanitary tissue is a through-dried fibrous structure.

19. The roll of claim 14 , 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.

20. The roll of claim 14 , wherein the sanitary tissue product exhibits an average Free Fiber End value of greater than about 1.5.
