Abstract

The present invention provides multi-ply creped tissue products, and in particular embodiments creped wet pressed tissue products, having substantially higher per-ply basis weights, such as from about 20 to about 30 gsm, without the negative effects often associated with higher basis weight. As such, the tissue products are generally soft and flexible, having a softness value (measured as TS7) less than about 12.0 and a Stiffness Index less than about 20. While being soft and flexible, the instant tissue products are durable enough to withstand use, such as having a GMT greater than about 600 g/3″ and a Burst Index greater than about 12.0.

Claims (9)

1. A creped tissue product comprising two or more plies, each ply having a basis weight greater than about 20.0 gsm, the tissue product having a geometric mean tensile (GMT) greater than about 600 g/3″ and a Stiffness Index less than about 20.

2. The creped tissue product of claim 1 having a MD Stretch greater than about 20 percent.

3. The creped tissue product of claim 1 having a MD Stretch from about 30 to about 35 percent.

4. The creped tissue product of claim 1 having a geometric mean stretch (GM Stretch) greater than about 12 percent.

5. The creped tissue product of claim 1 having a CD Stretch from about 5.0 to about 7.0 percent.

6. The creped tissue product of claim 1 having a GMT from about 700 to about 900 g/3″ and a geometric mean slope (GM Slope) from about 10 to about 15.

7. The creped tissue product of claim 1 having a TS7 value less than about 12.0.

8. The creped tissue product of claim 1 having a GMT from about 700 to about 900 g/3″ and a Stiffness Index from about 15.0 to about 17.0.

9. The creped tissue product of claim 1 wherein each ply has a basis weight from about 22.0 to about 25.0 gsm.
