Abstract

Products having improved caliper, sheet bulk and absorbency and methods for making those products are described. The method comprises producing a multi-ply product having different emboss patterns on each ply where the emboss patterns are made up of emboss elements having an aspect ratio of from about 1 to about 2.

First claim

What is claimed is:

1. A tissue product comprising,
at least two tissue plies, wherein the back-most ply is embossed with an emboss pattern that is a regular and continuous pattern and that comprises emboss elements having an aspect ratio of from about 1 to about 2, and a size of from about 0.015 to about 0.070 inches;
wherein the top-most ply is embossed with a decorative pattern that comprises decorative elements made up of discrete emboss elements having an aspect ratio of from about 1 to about 2, and a size of from about 0.015 to about 0.070 inches.

2. The tissue product of claim 1 , wherein the back-most ply is produced using conventional wet pressing.

3. The tissue product of claim 2 , wherein the top-most ply is produced using conventional wet pressing.

4. The tissue product of claim 1 , wherein adhesive is applied to the tops of the emboss elements of the decorative pattern on the top-most ply, and the plies are bonded.

5. The tissue product of claim 2 , wherein the top-most ply is produced using through-air-drying or another method for forming a structured base sheet.

6. The tissue product of claim 1 , wherein the density of the emboss elements on the back-most ply are from about 30 to about 150 embossments per square inch.

7. The tissue product of claim 1 , wherein the decorative pattern exhibits a bond area across the cross-machine direction (CD) of a repeat cell and a bond area across the machine direction (MD) of the same repeat cell each ranging from about 5% to about 20%.
