High bulk tissue product
View Patent ↗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.
1. A multi-ply paper product comprising:
at least two tissue plies produced by conventional wet pressing,
wherein the back-most ply is embossed with an emboss pattern that comprises non-linear 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 and a density of from about 30 elements/in 2 to about 380 elements/in 2 ;
wherein the top-most ply is embossed with a decorative pattern that comprises decorative elements made up of non-linear discrete emboss elements having an aspect ratio of from about 1 to about 2, and 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%;
wherein the pattern on the back-most ply is different from the decorative pattern on the top most ply; and
wherein the product has a caliper of between about 125 and 200 mils/8 sheets and a Sat Capacity of from about 1500 to about 1900 g/m 2 .
2. The paper 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.
3. The multi-ply paper product of claim 1 , wherein the back-most ply is embossed with an emboss pattern that comprises emboss elements having an aspect ratio of from about 1 to about 1.25.
4. The multi-ply product of claim 1 , wherein the density of the emboss elements on the back-most ply are from about 50 to about 150 elements/in 2 .
5. The multi-ply product of claim 1 , wherein the emboss elements on the back-most ply have a size of from about 0.040 to about 0.070.
6. The multi-ply product of claim 1 , wherein the emboss elements on the back-most ply have a size of from about 0.03 to about 0.05.
7. The multi-ply product of claim 1 , wherein the emboss elements on the back-most ply have a side wall angle between about 10 degree and about 30 degrees.
8. The multi-ply product of claim 1 , wherein the product is a rolled product and has a roll compression of from about 10% to about 30%.
9. The multi-ply product of claim 2 , wherein the product has a TMI ply bond of at least about 2 grams.
10. The multi-ply product of claim 2 , wherein the product has a TMI ply bond of at least about 5 grams.
