Abstract

The present disclosure is directed to a paper towel product that will capably separate from the paper towel roll as a full sheet, a half sheet or a quarter sheet. A method of making a paper towel with machine direction perforations is also disclosed.

Claims (25)

1. A partitionable folded napkin product comprising:

a napkin base sheet having a basis weight of at least about 31 g/sq. meter and a SAT absorbency of at least about 300 g/sq. meter;

at least one fold;

at least one perforation line that is coextensive with the at least one fold, the perforation line having a perforation tensile of at least about 550 g/3 inches and an average perforation bond area of at least about 15%; and

wherein the ratio of the perforation tensile strength in a first direction, either the machine direction or the cross-machine direction, and the tensile strength of the paper in a second direction perpendicular to the first direction is at least about 30%.

2. The folded napkin product of claim 1 , wherein the ratio of average perforation cut length to average perforation bond length is less than about 7.

3. The folded napkin product of claim 1 , wherein the at least one fold is in the cross-machine direction.

4. The folded napkin product of claim 1 , wherein the at least one fold is in the machine direction.

5. The folded napkin product of claim 1 , wherein the at least one perforation line divides the product in half.

6. The folded napkin product of claim 1 further comprising at least one second perforation line that divides that product into thirds.

7. The folded napkin product of claim 1 , wherein the at least one perforation line divides the product into quarters.

8. The folded napkin product of claim 1 , wherein the a least one perforation line is in the MD direction and the ratio of the CD tensile strength of the paper to the tensile strength of the MD perforation line is from about 30% to about 60%.

9. The folded napkin product of claim 1 , wherein the napkin product is a single ply product.

10. The folded napkin product of claim 1 , wherein the napkin product is a multi-ply product.

11. The folded napkin product of claim 1 , wherein the SAT absorbent capacity is at least about 400 grams/sq. meter.

12. The folded napkin product of claim 1 , wherein the perforation line comprises an average cut length of at least about 2.0 mm.

13. The folded napkin product of claim 1 , wherein the perforation line comprises an average bond length of at least about 0.5 mm.

14. The folded napkin product of claim 1 , wherein the cuts make up at least about 50% of the length of the perforation line.

15. The folded napkin product of claim 1 , further comprising

a base sheet having a basis weight of at least about 35 g/sq. meter;

wherein the napkin product comprises at least one fold in the machine direction and at least one fold in the cross-machine direction;

wherein the napkin product comprises at least one perforation line having an average cut length of at least about 2 mm and an average bond length of at least about 0.5 mm; and

wherein the perforation is coextensive with the last fold made in the napkin.

16. The folded napkin product of claim 1 , wherein the product is embossed.

17. The folded napkin product of claim 1 , wherein the ratio of the tensile strength of the paper in the first direction and the perforation tensile strength in the second direction is at least about 32%.
