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 single ply tissue product having a Geometric Mean Tensile (GMT) from about 2,500 to about 2,750 g/3″, a MD Slope from about 3.0 to about 5.0 kg and a Stiffness Index from about 2.0 to about 5.0.

2. The single ply tissue product of claim 1 having a basis weight from about 35 to about 70 gsm.

3. The single ply tissue product of claim 1 having a basis weight from about 50 to about 70 gsm.

4. The single ply tissue product of claim 1 having a Geometric Mean (GM) Stretch from about 15 to about 25 percent.

5. The single ply tissue product of claim 1 having a GM Stretch from about 18 to about 22 percent.

6. The single ply tissue product of claim 1 having a Machine Direction (MD)Stretch from about 45 to about 55 percent.

7. The single ply tissue product of claim 1 having a MD Tensile Energy Absorption (TEA) greater than about 45 g*cm/cm 2 .

8. The single ply tissue product of claim 1 having a GM Slope from about 4.0 to about 7.5.

9. The single ply tissue product of claim 1 having a GM Slope from about 4.0 to about 7.5, a GM Stretch from about 18 to about 22 percent and a MD TEA from about 40 to about 100 g*cm/cm 2 .

10. The single ply tissue product of claim 1 having a basis weight from about 50 to about 70 gsm and a GM Slope from about 4.0 to about 7.5.

11. A single ply tissue product having a basis weight from about 50 to about 70 gsm, a GMT from about 2,500 to about 2,750 g/3″, a GM Slope from about 4.0 to about 7.5 and a Stiffness Index from about 2.0 to about 5.0.

12. The single ply tissue product of claim 11 having a GM Stretch from about 15 to about 25 percent.

13. The single ply tissue product of claim 11 having a GM Stretch from about 18 to about 22 percent.

14. The single ply tissue product of claim 11 having a MD Stretch from about 45 to about 55 percent.

15. The single ply tissue product of claim 11 having a MD TEA greater than about 45 g*cm/cm 2 .

16. The single ply tissue product of claim 11 having a MD TEA from about 40 to about 100 g*cm/cm 2 .
