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 7%, 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.

Claims (20)

1. Rolls of sanitary tissue products, each comprising a shaped line of weakness such that the line of weakness is nonlinear, wherein the rolls of sanitary tissue products exhibit a roll compressibility (of the rolls) of less than about 7%, and the rolls of sanitary tissue products have a Full Sheet Average Trapezoidal Tear Strength (across shaped lines of weakness) of about 8 g to about 20 g, as measured by a Full Sheet Average Trapezoidal Tear Force Method.

2. The rolls of claim 1 , wherein the rolls of sanitary tissue products exhibit a roll compressibility (of the rolls) of less than about 4%.

3. The rolls of claim 1 , wherein the rolls of sanitary tissue products exhibit a roll compressibility (of the rolls) of less than about 3%.

4. The rolls of claim 1 , wherein the rolls of sanitary tissue products exhibit a Full Sheet Average Trapezoidal Tear Strength (across shaped lines of weakness) of about 10 g to about 18 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method.

5. The rolls of claim 1 , wherein the rolls of sanitary tissue products exhibit a Full Sheet Average Trapezoidal Tear Strength (across shaped lines of weakness) of about 11 g to about 17 g, as measured by the Full Sheet Average Trapezoidal Tear Force Method.

6. The rolls of claim 1 , wherein the rolls of sanitary tissue product exhibit a Dry Burst (of a sample of the roll of sanitary tissue product) of between about 100 g and about 1000 g, as measured according to a Dry Burst Test Method.

7. The rolls of claim 1 , wherein the rolls of sanitary tissue product are through-dried fibrous structures.

8. The rolls of claim 1 , wherein the rolls of sanitary tissue product are uncreped fibrous structures.

9. Rolls of sanitary tissue products, each 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 the roll) of less than about 6%, and the roll of sanitary tissue product has a Full Sheet Average Trapezoidal Tear Strength (across replicates of shaped lines of weakness) of about 8 g to about 20 g, as measured by a 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 a Basis Weight Test Method.

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

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

12. The rolls of claim 9 , wherein the rolls of sanitary tissue product exhibit a Dry Burst (of samples from the roll of sanitary tissue product) of between about 100 g and about 1000 g, as measured according to a Dry Burst Test Method.

13. The rolls of claim 9 , wherein the rolls of sanitary tissue product are through-dried fibrous structures.

14. The rolls of claim 9 , wherein the rolls of sanitary tissue product are uncreped fibrous structures.

15. Rolls of sanitary tissue products, each 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 the roll) of less than about 6%, and the roll of sanitary tissue product has a Full Sheet Average Trapezoidal Tear Strength (across replicates of shaped lines of weakness) of about 8 g to about 20 g, as measured by a Full Sheet Average Trapezoidal Tear Force Method, and a Geometric Mean Peak Elongation (of specimens from the roll of sanitary tissue product) of greater than about 15%, as measured according to a Dry Tensile Strength Test Method.

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

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

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

19. The rolls of claim 15 , wherein the rolls of sanitary tissue product are through-dried fibrous structures.

20. The rolls of claim 15 , wherein the rolls of sanitary tissue product are uncreped fibrous structures.
