As a result, the part 20 of the next sanitary thin paper becomes excellent in self-sustainability and fall prevention.
  • the edge 20E and the edge 20E of the part 20 of the sanitary thin paper 3 to be subsequently drawn out when one or a set is pulled out.
  • the surface moves toward the outlet while moving in the depth direction 3D, and is guided by the edge of the outlet 60 when exposed from the outlet 60.
  • the outlet 60 becomes wider from the position between the end narrowed portion 51 and the widened portion 52 toward the end narrowed position, a part 20 of the sanitary thin paper 2 is pulled out. In this case, the edge 20E of the sanitary thin paper 2 is easily guided to the corner P.
  • the surface of the sanitary thin paper 2 is reliably supported by the edge. It is more drip-proof.
  • the distance between the first easily tearable lines 5A and 5A is set to 10% or less and the connecting portion 54 in which the interval between the pair of first easily tearable lines is constant is provided, the surface of the sanitary thin paper 2 is supported more. It is easier to fall and the anti-dropping property is improved.
  • the pair of first easily tearable open lines 5A, 5A in the end narrowed portion 51 and the widened portion 52 be curved. Since the edge E of the outlet 60 has a smooth curve, the guide of the sanitary thin paper 2 by the edge is smoothly performed, and the drawability is further improved. Further, the overall shape of the wide portion 53 is not particularly limited, but is preferably a circle, an ellipse, or a square having a curved edge as in the illustrated example. It is hard to catch on the edge when pulling out, making it easy to pull out smoothly.
  • the length PW of the bundle 3 of the first easily tearable open lines 5A, 5A in the width direction 3W is shorter than the width L2 of the bundle 3 in the width direction, particularly 87 to 97%. It is desirable to have. If it exceeds 97%, it becomes difficult for the edge 20E of the sanitary thin paper 2 to enter the corner P.
  • the length EW of the second easily tearable line 5B in the sanitary thin paper package 1 according to the present invention is desirably 3 to 16% of the length L1 of the bundle 3 in the depth direction 3D. In this range, the edge 20E easily enters the corner P.
  • the width Bh of the edge piece 61 that is, the line Bb (line) connecting the corner P1 (one of the corners P) and the corresponding point P2 of the edge of the wide portion 53.
  • Bb is a tangent to the outer edge of the wide portion 53 and passes through the corner P1), and the length Bh from the opening edge E is desirably 8 to 24 mm.
  • the position P2 on the edge side of the wide portion 53 in the line Bb connecting the corner P and the edge of the wide portion 53 is a position where the width Bh is the longest. In the range of the above width Bh, if the size of a general sanitary thin paper is used, it can be sufficiently held and held.
  • the first easily tearable open line 5A and the second easily tearable open line 5B in the sanitary thin paper package 1 according to the present invention are constituted by perforations or slits having an uncut portion at an appropriate position as described above. More preferably, the first easy tearing line 5A is formed as a slit communicating with the inside and outside in the end narrowing portion 51 and the widening portion 52, and the tie is 0.5 mm to 3 mm in the connecting portion 54 and the wide portion 53. It is desirable to use a perforation of 0.0 mm and a cut of 1.0 mm to 7.00 mm.
  • the connecting portion 54 and the wide portion 53 have a tie of 1.5 mm to 2.5 mm and a cut of 2.0 mm to 5.0 mm. It is less likely to break during transportation or loading, and is more likely to break with fingers.
  • the second easily tearable line 5B is desirably a perforation where the position of the corner P is cut or a slit provided with an uncut portion at the center in the depth direction 3D. As shown in FIG. 6, when the package is constituted by the slits and perforations, as shown in FIG.
  • the end stenosis portion 51 becomes a torn portion which is peeled off, and when the stenosis portion is pulled toward the opposite end stenosis portion 51, the first easy tearing line 5A is obtained.
  • the opening forming portion 50 surrounded by the second easy tearing line 5B is smoothly peeled off, and the opening 60 can be easily formed, so that the opening property is excellent.
  • specific flexible resin film materials constituting the film 4 according to the present invention include polyethylene film, polypropylene film, polyester film, polyethylene terephthalate film, nylon film, vinylidene chloride film, ethylene vinyl alcohol.
  • examples thereof include a monolayer film of a copolymer, a laminated film appropriately laminated including such a film, and a gas barrier film obtained by subjecting such a film to a surface treatment such as aluminum vapor deposition.
  • a polypropylene film and a polyethylene film are preferred.
  • a non-stretched polypropylene film (CPP) having excellent heat-fusibility is desirable.
  • the thickness of the film 4 may be appropriately selected in consideration of flexibility, cost, gas permeability, and heat-sealing property during packaging, but is preferably measured in accordance with JIS P # 8118 (1998). It is desirable that the thickness is 20 to 60 ⁇ m and the softness is 5.0 to 50.0 cN, which is measured based on the handle ometer method according to the JIS ⁇ L @ 1096 (2010) ⁇ E method. With such a thickness and softness, the film is hardly torn and the pop-up property is excellent.
  • Comparative Example 5 has an opening forming portion formed of one perforation, particularly along the bundle width direction, and the outlet is a linear slit.
  • the tie cut ratio is 2 mm tie and 3 mm cut.
  • the packaging forms are all overlap packaging, and the sealing portion is formed by heat sealing.
  • the product outer shell dimensions and the bundle dimensions were prepared in substantially the same manner except for manufacturing errors, and the bundles were commercially available S size and M size.
