  • the fourth cleavage line is formed at a position separated from the top surface side to the bottom surface side by a length of 20% or more and 80% or less of the length of the third side surface in the third direction. While locking the deployed lid to the first edge of the top surface, it is possible to prevent the third side surface from breaking. Further, the developed lid is formed by forming a fifth cleavage line at a position separated from the top surface side to the bottom surface side by a length of 20% or more and 80% or less of the length of the fourth side surface in the third direction. While locking the body to the second edge of the top surface, it is possible to prevent the fourth side surface from breaking.

  • the central portion of the top surface includes the center of the top surface (center of gravity) and indicates an area having an area of about 1/10 to 1/5 of the entire top surface.
  • the outlet is formed in the central portion of the top surface, the outlet is not formed on the entire top surface. Therefore, the shape of the packaging bag is easily maintained even after the outlet is opened, and the storage state of the sheet in the packaging bag is not easily disturbed. Therefore, according to the sixth aspect, the sheet package can be used cleanly to the end.
  • the outlet in the central portion of the top surface, the outlet can be opened in the central portion of the top surface.
  • the sheet when the sheet is taken out from the outlet, the sheet can be pulled out from the central portion of the top surface. Therefore, according to the sixth aspect, the sheet can be easily taken out from the take-out port, and the sheet can be taken out stably from the take-out port.
  • a seventh aspect according to the present invention is a sheet package in which the area of the outlet is 20% or more and 60% or less with respect to the area of the top surface.
  • the outlet is not formed on the entire top surface. Therefore, in the seventh aspect, it is possible to provide a hygienic sheet package in which dust does not easily enter the packaging bag from the top surface.
  • the outlet is not formed on the entire top surface, the shape of the packaging bag can be easily maintained even after the outlet is opened. Therefore, the storage state of the sheet in the packaging bag is not easily disturbed, and the sheet package can be used neatly to the end.
  • An eighth aspect according to the present invention is a sheet package in which an adhesive seal is provided at an end portion of the lid body on the second side surface side.

  • the adhesive seal indicates a seal that adheres to the top surface while being fixed to the lid.
  • the adhesive seal since the adhesive seal is provided at the end on the second side surface side of the lid, the adhesive seal can be pinched as a trigger for opening a part of the top surface. Then, when this trigger is pulled upward, a part of the top surface is cleaved to form an outlet that opens to the top surface, and a part of the cleaved top surface is a lid that closes the outlet so that the outlet can be resealed. Can be configured.
  • the outlet can be opened without pressing the top surface of the packaging bag. Therefore, in the eighth aspect, it is possible to prevent the sheet from being torn when the outlet is opened.
  • the lid body since the lid body is provided with such an adhesive seal, the lid body can be adhered to the top surface with the outlet closed. This makes it easy to close (reseal) the outlet with the lid. Further, the shape of the packaging bag is easily maintained when the outlet is closed, and the storage state of the sheet in the packaging bag is not easily disturbed. Further, since the closed state of the lid is maintained, it is possible to prevent dust from entering the packaging bag from the closed outlet.
  • the lid is provided with such an adhesive sticker, there is a risk that the sheet will stick to the adhesive sticker when the sheet is taken out from the outlet.
  • the deployed lid is locked to the first edge and the second edge of the top surface, and the lid is maintained in a state of being separated from the outlet. Therefore, in the eighth aspect, even when the adhesive sticker is provided on the lid, the sheet is difficult to stick to the adhesive sticker.
