- the packaging form of the package 1 is not limited.
- a simple pillow packaging without a gusset may be used, or other appropriate packaging forms such as overlap packaging, also called caramel packaging, formed by overlapping and fused flaps on the short sides may be used.
- the bundle 3 of sanitary thin paper 2 contained in the package 1 according to the present invention is a so-called pop-up bundle. As shown particularly in FIG. 2, this bundle 3 is such that the rectangular sanitary thin paper 2 is folded in two, and the folded pieces 2B of the other sanitary thin papers 2 located above and below are positioned on the folded inner side 2A.
- a plurality of sanitary thin paper sheets 2 are folded and laminated, and has a pair of longitudinal side surfaces 3B where the folding edges 2C of each sanitary thin paper sheet 2 are arranged, a pair of short side surfaces 3A where the folding edges 2C are not arranged, and further the short side surfaces. It has a substantially rectangular parallelepiped shape having a pair of flat surfaces (upper and lower surfaces) 3C that are connected to 3A and longitudinal side surfaces 3B.
- the number of sets of sanitary thin paper 2 constituting the bundle 3 is not limited, but can be 30 to 240 sets with one ply or multiple plies as one set.
- the size of the bundle 3 is also not limited, but a bundle of 200 sets of sanitary thin paper is preferably 30 to 100 mm in height x 150 to 250 mm in the longitudinal direction (width) x 100 to 130 mm in the lateral direction (depth). . Further, when the height of the bundle is shorter than the length of the upper surface of the bundle in the depth direction, the pop-up failure improvement effect of the present invention is enhanced.
- the filling rate of the bundle 3 in the package 1 is not limited as long as it does not interfere with the effects of the present invention, but the gap between the bundle and the packaging film is preferably in the range of 0 to 30 mm.
- the bundle 3 may be wrapped in a slightly compressed state in the vertical direction with the wrapping film.
- Each of the sanitary thin papers 2 constituting the bundle 3 has a single-layer structure of one sheet or a laminated structure of a plurality of sheets.
- the number of plies is not limited, it is preferable to use one layer (1 ply) or two layers (2 plies).
