摘要:
Provided is a moisturized tissue excellent in strength and snot wiping property. In the moisturized tissue paper, a paper thickness is 220 to 330 μm, a basis weight is 15 to 18 g/m2 per ply, a proportion of NBKP in the pulp combination is more than 70 mass %, a chemical solution content is 26 to 32 mass %, an arithmetic mean curvature at a peak point of an outer surface in an unpressurized state (Spc (1)) is 4.0 to 4.8 (1/mm), and a developed area ratio at an interface on the outer surface (Sdr) is 0.020 to 0.030 (−).
