Bag

A bag having a storage section, comprising:

• laminated bodies that include a sealant film positioned on an inner surface of the bag and at least one plastic film positioned on an outer surface side of the sealant film;
• and
• a seal section where inner surfaces of one pair of laminated bodies are joined together,
• wherein the seal section has an outer edge seal part that is positioned along an outer edge of the bag, and a steam-releasing seal part that is positioned closer to a center point side of the storage section than the outer edge seal part and that peels off due to an increase in pressure in the storage section,
• wherein the outer edge seal part includes an upper seal section that extends along an upper portion of the bag, a lower seal section that extends over a lower portion of the bag, a first side seal section that extends along a first side portion of the bag, and a second side seal section that extends along a second side portion of the bag,
• wherein the steam-releasing seal part has a shape that protrudes from the first side seal section toward the inside of the bag,
• wherein the bag comprises a non-seal section that is isolated from the storage section by the steam-releasing seal part and extends to the outer edge of the first side portion,
• wherein the sealant film comprises polyethylene and 51% by mass or more of propylene/ethylene block copolymer,
• wherein a tensile elongation (%) of the sealant film in a machine direction is 800% or more,
• wherein a tensile elongation (%) of the sealant film in a transverse direction is 1,050% or more,
• wherein a product of the tensile elongation (%) of the sealant film in the machine direction and a thickness (μm) of the sealant film is 45,000 or more,
• wherein a product of the tensile elongation (%) of the sealant film in the transverse direction and the thickness (μm) of the sealant film is 53,000 or more, and
• wherein a ratio of a distance H1 to a distance H2 is 1.04 or more and 1.12 or less,
• wherein the distance H1 is a distance from the upper seal section to a center point of the storage section, and
• wherein the distance H2 is a shortest distance from the steam-releasing seal part to the center point of the storage section.
