Abstract

Disclosed are embossed, multi-ply tissue products having consumer preferred physical properties and an aesthetically pleasing appearance. The products may have a first ply embossed with a first pattern comprising line emboss elements and a second ply embossed with a second embossing pattern comprising dot emboss elements. In addition to having plies with different embossing patterns, the plies may have different tensile strength, such as a first ply having a geometric mean tensile (GMT) strength greater than 500 g/3″ and a second ply having a GMT less than 500 g/3″. Preferably the difference in the GMT between the first and second plies is at least about 20 percent, such as from about 20 to about 50 percent.

First claim

What is claimed is:

1. An embossed multi-ply tissue product comprising:
a. a first embossed tissue ply;
b. a second embossed tissue ply,

wherein the first embossed tissue ply has a geometric mean tensile strength that is at least about 20 percent greater than the geometric mean tensile (GMT) strength of the second embossed tissue ply.

2. The embossed multi-ply tissue product of claim 1 wherein the product has a GMT from about 700 to about 1,200 g/3″.

3. The embossed multi-ply tissue product of claim 1 wherein the first embossed tissue ply has a GMT greater than about 500 g/3″ and the second embossed tissue ply has a GMT less than about 500 g/3″.

4. The embossed multi-ply tissue product of claim 1 wherein the first embossed tissue ply has a MD Tensile greater than about 750 g/3″ and the second embossed tissue ply has a MD Tensile less than about 550 g/3″.

5. The embossed multi-ply tissue product of claim 1 having a basis weight from about 20 to about 60 grams per square meter (gsm) and a bulk greater than about 15 cubic centimeters per gram (cc/g).

6. The embossed multi-ply tissue product of claim 1 wherein the first embossed tissue ply has a CD TEA greater than about 2.0 gf*cm/cm 2 and the second embossed tissue ply has a CD TEA less than about 1.0 gf*cm/cm 2 .

7. The embossed multi-ply tissue product of claim 1 wherein the first embossed tissue ply has a first embossed pattern consisting essentially of line emboss elements and the second embossed tissue ply has a second embossed pattern consisting essentially of dot emboss elements.

8. The embossed multi-ply tissue product of claim 1 wherein the first ply comprises a plurality of embossments disposed in a first pattern, the second ply comprises a plurality of embossments disposed in a second pattern and wherein both the first and the second plies comprise a through-air dried tissue ply having a molded topographical pattern.

9. The embossed multi-ply tissue product of claim 8 wherein the molded topographical pattern, the first pattern of embossments and the second pattern of embossments comprise a plurality of wave-like linear elements.

10. The embossed multi-ply tissue product of claim 8 wherein first pattern of embossments consists essentially of line emboss elements and covers from about 10 to about 30 percent of the first ply surface area; and wherein the second pattern of embossments consists essentially of dot emboss elements and covers from about 5 to about 10 percent of the second ply surface area.
