wherein the rolled paper towel product has a basis weight of from about 43 g/sq. meter to about 51 g/sq. meter; and
wherein the rolled paper towel product has a SAT absorbent capacity of from about 300 g/sq. meter to about 550 g/sq. meter.
2 . The rolled paper towel product of claim 1 , wherein the at least one perforation line in the machine direction comprises a series of homogenous perforations, wherein each perforation comprises a cut having a cut length and a bond having a bond length, wherein the sum of the cut length and the bond length constitutes the perforation length.
3 . The rolled paper product of claim 2 , wherein each of the plurality of perforation lines in the cross-machine direction comprises a series of homogenous perforations, wherein each perforation comprises a cut having a cut length and a bond having a bond length, wherein the sum of the cut length and the bond length constitutes the perforation length.
4 . The rolled paper product of claim 3 , wherein the perforations in the at least one perforation line in the machine direction have a ratio of the cut length to the bond length of from about 2.5 to about 7.
5 . The rolled paper product of claim 3 , wherein the perforations in the plurality of perforation lines in the cross-machine direction have a ratio of the cut length to the bond length of from about 3 to about 8.
6 . The rolled paper towel product of claim 3 , wherein the perforation length of the perforations in the at least one perforation line in the machine direction is shorter than the perforation length of the perforations in the plurality of perforation lines in the cross-machine direction.
7 . The rolled paper towel product of claim 3 , wherein:
the perforations in the at least one perforation line in the machine direction have a ratio of the cut length to the bond length of from about 2.5 to about 7;
the perforations in the plurality of perforation lines in the cross-machine direction have a ratio of the cut length to the bond length of from about 3 to about 8; and
the perforation length of the perforations in the at least one perforation line in the machine direction is shorter than the perforation length of the perforations in the plurality of perforation lines in the cross-machine direction.
8 . The rolled paper towel product of claim 1 , wherein the ratio of the tensile strength of the at least one perforation line in the machine direction to the tensile strength of each of the plurality of perforation lines in the cross-machine direction is at least about 1.5.
9 . The rolled paper towel product of claim 1 , wherein the paper towel product has a basis weight of at least from about 43 g/sq. meter to about 46 g/sq meter.
10 . The rolled paper towel product of claim 1 , wherein the tensile strength of the at least one perforation line in the machine direction is greater than about 770 g/3 inches.
11 . The rolled paper towel product of claim 1 , wherein the tensile strength of each of the plurality of perforation lines in the cross-machine direction is greater than about 450 g/3 inches.
12 . The rolled paper towel product of claim 1 , wherein the paper towel product has a SAT absorbent capacity of from about 300 g/sq. meter to about 450 g/sq. meter.
13 . The rolled paper towel product of claim 1 , wherein the ratio of the tensile strength of the at least one perforation line in the machine direction to the tensile strength of the paper web in the cross-machine direction is from about 30% to about 60%.
14 . The rolled paper towel product of claim 1 , wherein the ratio of (i) the ratio of the tensile strength of the at least one perforation line in the machine direction to the tensile strength of the paper product in the cross-machine direction to (ii) the ratio of the tensile strength of each of the plurality of perforation lines in the cross-machine direction to the tensile strength of the paper product in the machine direction is between about 1.7 and about 2.
15 . The rolled paper towel product of claim 1 , wherein the tensile strength of the at least one perforation line in the machine direction is greater than about 770 g/3 inches; wherein the tensile strength of each of the plurality of perforation lines in the cross-machine direction is greater than about 450 g/3 inches; and wherein the ratio of the tensile strength of the at least one perforation line in the machine direction to the tensile strength of each of the plurality of perforation lines in the cross-machine direction is at least about 1.5.
