Abstract: A laminate according to the present disclosure is a laminate including at least a first sealant layer, a vapor deposition film, and a second sealant layer in this order, wherein the first sealant layer includes at least a polyethylene resin layer and a surface resin layer, the vapor deposition film is located on the surface resin layer of the first sealant layer, the second sealant layer is composed of a polyethylene resin, and the surface resin layer of the first sealant layer contains a resin material with a melting point of 150° C. or more.

Abstract: To suppress damage such as the formation of holes and wrinkles in laminated bodies constituting a bag. A bag having a storage section includes: 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. 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 peels off due to an increase in pressure in the storage section. The steam-releasing seal part peels off when the pressure in the storage section is 130 kPa or lower.
