Abstract

The present invention provides tissue products having a high degree of stretch and low modulus at relatively high tensile strengths, such as geometric mean tensile strengths greater than about 1500 g/3″ and more preferably greater than about 2000 g/3″. The combination of a tough, yet relatively supple sheet is preferably achieved by subjecting the embryonic web to a speed differential as it is passed from one fabric in the papermaking process to another, commonly referred to as rush transfer.

Claims (16)

1. A tissue product having a MD TEA (expressed as g*cm/cm 2 ) equal to or greater than about 45 and a GMT from about 2200 to about 2750 g/3″.

2. The tissue product of claim 1 having a percent MD Stretch greater than about 25 percent.

3. The tissue product of claim 1 having a MD Slope less than about 10.0 kg/3″.

4. The tissue product of claim 1 having a GM Slope less than about 7.5 kg/3″.

5. The tissue product of claim 1 having a Stiffness Index less than about 5.0.

6. The tissue product of claim 1 having a bone dry basis weight greater than about 50 gsm.

7. The tissue product of claim 6 wherein the at least one through-air dried tissue ply is uncreped.

8. The tissue product of claim 1 having a bone dry basis weight from about 50 to about 70 gsm.

9. The tissue product of claim 1 wherein the product comprises at least one through-air dried tissue ply.

10. A single ply uncreped through-air dried tissue web having a basis weight from about 50 to about 70 gsm, a MD TEA greater than about 45 g*cm/cm 2 and a GMT from about 2200 to about 3500 g/3″.

11. The tissue product of claim 10 having a percent MD Stretch greater than about 25 percent.

12. Tissue product of claim 10 wherein the MD TEA is from about 45 to about 70 g*cm/cm 2 .

13. The tissue product of claim 10 having a MD Slope less than about 10.0 kg/3″.

14. The tissue product of claim 10 having a GM Slope less than about 7.5 kg/3″.

15. The tissue product of claim 10 having a Stiffness Index less than about 5.0.

16. The tissue product of claim 10 having a Stiffness Index from about 4.0 to about 5.0.
