First claim

What is claimed is:

1. A partitionable paper product of at least one paper web, comprising:
a basis weight of at least about 20 g/sq. meter;
least one perforation line in the CD direction having a perforation strength and wherein the perforation strength is between about 450 grams/3 inches and about 950 grams/3 inches;
at least one perforation line in the MD direction having a perforation strength and wherein the perforation strength of the perpendicular perforation line is between about 300 grams/3 inches and about 1700 grams/3 inches;
wherein the perforation strength in the MD direction is greater than the perforation strength in the CD direction; and
wherein the ratio of the tensile strength of the MD perforation line to the CD tensile strength of the paper is from about 30% to about 70%.

2. The paper product of claim 1 , wherein the ratio of the tensile strength of the CD perforation line to the MD tensile strength of the paper is from about 30% to about 40%.

3. The paper product of claim 1 , wherein the paper product is a folded paper product.

4. The paper product of claim 1 , wherein the paper product is a rolled paper product.
