摘要： To provide tissue paper excellent in softness and smoothness. In tissue paper that is two-ply non-moisturizing tissue paper to which no chemical solution is applied, a basis weight per sheet is 10.0 to 18.0 g/m2, the thickness of two plies is 100 to 240 μm, a dry tensile strength in the paper horizontal direction is 70 to 180 cN/25 mm, a wet tensile strength in the paper horizontal direction is 25 to 55 cN/25 mm, and a free sensory evaluation value Ef calculated according to the following Equation 1 is 3.7 to 6.6, and a slip sensory evaluation value Es calculated according to the following Equation 2 is 5.0 to 8.2.
Free sensory evaluation value Ef=−2.879×(dry tensile strength in paper horizontal direction)+6.55×(wet tensile strength in paper horizontal direction)+5.36 (Equation 1)
Slip sensory evaluation value Es=−8.80×(dynamic friction coefficient)−0.41×(arithmetic mean surface roughness)+13.58 (Equation 2)-

摘要： A moisturizing tissue product that can be packaged in the same way as a non-moisturizing tissue product. With this tissue paper product in which a web obtained by folding and laminating in a pop-up configuration a plurality of sheets of tissue paper containing a moisturizing agent is stored in a rectangular-shaped paper box having an outlet on an upper surface thereof, the problem of the tissue paper is solved by this tissue paper product in which the number of plies is 2.

摘要： The present invention is directed to a two-ply tissue paper including a polyol-containing moisturizer and having excellent softness, smoothness, and strength. In various embodiment, the two-ply tissue paper of the present invention has a basis weight of 16.0 to 25.0 g/m2 per ply, a two-ply paper thickness of 145 to 180 μm, a dry tensile strength of 120 to 200 cN/25 mm in a lateral direction, a dry tensile strength of 275 to 450 cN/25 mm in a longitudinal direction, a wet tensile strength of 60 to 130 cN/25 mm in the lateral direction, a difference of 40 cN/25 mm or more between the dry tensile strength in the lateral direction and the wet tensile strength in the lateral direction and a value of (wet tensile strength in lateral direction)/(dry tensile strength in lateral direction) of 0.60 to 0.75, and an elongation percentage of 13.0 to 18.0% in the longitudinal direction.

摘要： A pocket tissue includes a stack of paper tissues each of which is folded at a plurality of fold portions and a film package that contains the stack, the pocket tissue allowing the paper tissues to be taken out from a dispense opening formed in an upper surface of the package. Each of the paper tissues includes a first fold portion located at a position that substantially bisects the paper tissue, a second fold portion extending in a longitudinal direction of the paper tissue folded at the first fold portion, and a third fold portion extending in a transverse direction of the paper tissue folded at the second fold portion. The stack is formed by stacking the paper tissues each of which has been folded at the third fold portion to be in a state in which the first fold portion is exposed to the outside.
