THIN SANITARY PAPER ROLL, METHOD OF MANUFACTURING THE PAPER ROLL, AND THIN SANITARY PAPER FOR THIN SANITARY PAPER ROLL

摘要

A sanitary tissue paper roll wherein, when a sanitary tissue paper roll of two-ply or three-ply is laid on a horizontal surface with its center axis in a horizontal orientation; and a circular plate indenter, having an area of 2 cm2 and being arranged at the center of an upper surface of an outer periphery of a body of said roll, is vertically pressed at least at respective pressing pressures of 0.5 gf/cm2 and 50 gf/cm2, a difference in depths upon said respective pressing is within a range of 2.5-3.5 mm. A sanitary tissue paper roll made by winding one sheet or two layered sheets of sanitary tissue papers wherein a roll compressibility of said roll is 0.68-0.74 m/cm2, said roll compressibility being defined as a value obtained by dividing a roll length by a cross section of said roll. A sanitary tissue paper for a sanitary tissue paper roll, wherein a sample paper is compressed between steel plates, which respectively have a circular surface with a compression area of 2 cm2, at a maximum compression load of 50 gf/cm2, and upon returning of said paper sample, a linearity of a displacement curve between a load and a thickness is 0.2500-0.3300 for a one-ply, and 0.3400-0.3700 for a two-ply; and a thickness upon a load of 50 gf/cm2 is equal to or above 0.1400 mm for a one-ply, and equal to or above 0.2500 mm for a two-ply.
