The thin paper package P is an example of the thin paper package according to the present invention.

  The thin paper T is not particularly limited as long as a plurality of sheets are laminated, but is preferably a laminated body in which a plurality of folded thin papers are laminated. The laminate of thin paper T is not limited to a simple lamination of a plurality of thin papers, but is laminated with each thin paper folded, or alternately laminated with each thin paper folded (So-called pop-up thin paper) may be used.

  The number of plies of each thin paper constituting the thin paper T is not particularly limited, but can be 1 ply or more, preferably 2 plies. The shape of the thin paper T is not particularly limited. For example, it is preferable that the shape of the thin paper T is rectangular when the two-ply thin paper is folded.

  The form of the thin paper T is not particularly limited, and can be applied to tissue paper, toilet paper, kitchen paper, paper towel, and the like. These sanitary thin paper also includes sanitary thin paper (for example, lotion tissue) containing a moisturizing component. Moreover, the use of sanitary thin paper is not limited, and any of industrial use, household use, and portable use can be applied. Among these, portable sanitary thin paper (for example, pocket tissue) such as tissue paper and toilet paper containing a moisturizing component is preferable.

The basis weight of the thin paper T is preferably in the range of 10 to ²⁰ g / m ² per two plies, and the paper thickness in the two plies of thin paper is preferably in the range of 130 to 200 μm. Here, the basis weight indicates a value measured based on JIS P 8124 (1998). The paper thickness was adjusted sufficiently under the conditions of JIS P 8111 (1998), and then a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho) was used under the same conditions. Shows the measured value.

  A specific procedure for measuring the paper thickness is as follows. First, after confirming that there is no dust, dust, etc. between the plunger and the measurement table, lower the plunger on the measurement table and move the dial thickness gauge memory to adjust the zero point. The plunger is then raised and the sample is placed on the test bench, the plunger is slowly lowered, and the gauge at that time is read. In this case, just place the plunger. The terminal of the plunger is made of a metal and a circular plane having a diameter of 10 mm is perpendicular to the paper plane. The load at the time of measuring the paper thickness is about 70 gf. The paper thickness is an average value obtained by performing measurement 10 times.

  The strength of the thin paper T is preferably 120 to 600 cN, more preferably 130 to 450 cN, and particularly preferably 140 to 300 cN in the longitudinal direction in two plies.
