Abstract
A cellulosic sheet includes a single ply providing a first surface of the cellulosic sheet on one side and a second surface of the cellulosic sheet on a second side. The single ply has a caliper of at least about 130 mils/8 sheets, a basis weight of less than about 16 lbs/ream, and a dry machine direction/cross machine direction (MD/CD) tensile ratio of less than about 1.0.
Claims17
A cellulosic sheet having a first surface and a second surface, the cellulosic sheet comprising:
- a single ply providing the first surface of the cellulosic sheet on one side and the second surface of the cellulosic sheet on a second side,
- wherein the single ply has (i) a caliper of at least about 130 mils/8 sheets, (ii) a basis weight of less than about 16 lbs/ream, and (iii) a dry machine direction/cross machine direction (MD/CD) tensile ratio of less than about 1.0.
A cellulosic sheet made by a method that comprises:
- (a) forming an aqueous cellulosic web on a structuring fabric in a papermaking machine;
- (b) non-compactively dewatering the cellulosic web on the structuring fabric;
- and
- (c) drying the cellulosic web to form a single ply cellulosic sheet,
- wherein a portion of the structuring fabric on which the cellulosic web is formed has an adjusted planar volumetric index of at least about 27, and
- wherein the single ply has (i) a caliper of at least about 130 mils/8 sheets, (ii) a basis weight of less than about 16 lbs/ream, and (iii) a dry machine direction/cross machine direction (MD/CD) tensile ratio of less than about 1.0.
