Abstract

A method of increasing the density and reducing the bulk of multi-ply paper products allowing one to reduce the roll size or increase the roll content, while minimizing the destruction of favorable product attributes.

Claims (16)

1. A method of making a rolled paper product comprising:

providing at least one paper web;

embossing the at least one web using an emboss pattern that covers at least about 22% of the total surface area of the at least one web an emboss depth of about 1.25 about 3.5 times the caliper of the unembossed at least one web and which pattern includes at least about 80% linear embossments and;

wherein in the caliper of the finished product is less than the caliper of the unembossed at least one web from which it is formed.

2. The method of claim 1 wherein the emboss pattern covers 22 to 50% of the paper web.

3. The method of claim 1 wherein the emboss pattern covers 25 to 30% of the paper web.

4. The method of claim 1 wherein the emboss pattern includes at least about 90% linear embossments.

5. The method of claim 1 wherein the emboss pattern includes at least about 95% linear embossments.

6. The method of claim 1 wherein the emboss pattern includes 100% linear embossments.

7. The method of claim 1 , wherein the depth of embossments are from about 1.5 to about 2.5 times the caliper of the unembossed at least one web.

8. The method of claim 1 , wherein the depth of embossments are from about 1.5 to about 2.0 times the caliper of the unembossed at least one web.

9. The method of claim 1 , wherein the paper product comprises two or more webs, and wherein the embossing step both embosses and plies the webs.

10. A paper product comprising,

at least one paper web having an embossed surface wherein the emboss pattern is made up of at least about 80% linear elements and the emboss depth is form about 1.25 to about 3.5 times the caliper of the unembossed at least one web;

wherein the finished product has a caliper less than the caliper of the unembossed at least one web from which it is formed; and

wherein the emboss pattern covers 22 to 50% of the paper surface.
