Abstract:
(EN) [Problem] To suppress damage such as the formation of holes and wrinkles in laminated bodies constituting a bag. [Solution] A bag having a storage section comprises: laminated bodies including a sealant film positioned on the inner surface of the bag and at least one plastic film positioned on the outer surface side of the sealant film; and a seal section where the inner surfaces of one pair of laminated bodies are joined together. The seal section has: an outer edge seal part positioned along the outer edge of the bag; and a steam-releasing seal part positioned closer to the center point side of the storage section than to the outer edge seal part that peels off as the pressure in the storage section increases. The steam-releasing seal part peels off when the pressure in the storage section is 130 kPa or lower.
(FR) Le problème décrit par la présente invention est de supprimer les dégâts tels que la formation de trous et de rides dans des corps stratifiés constituant un sac. La solution selon l’invention porte sur un sac présentant une section de stockage comprenant : des corps stratifiés comprenant un film d’agent d’étanchéité positionné sur la surface interne du sac et au moins un film en matière plastique positionné sur le côté de surface extérieure du film d’agent d’étanchéité ; et une section d’étanchéité où les surfaces internes d’une paire des corps stratifiés sont jointes ensemble. La section d’étanchéité présente : une partie d’étanchéité du bord externe positionnée le long du bord externe du sac ; et une partie d’étanchéité à dégagement de vapeur positionnée plus près du côté point central de la section de stockage que la partie d’étanchéité du bord externe qui se décolle lorsque la pression dans la section de stockage augmente. La partie d’étanchéité à dégagement de vapeur se décolle lorsque la pression dans la section de stockage est de 130 kPa ou moins.
(JA) [課題]袋を構成する積層体に穴やシワなどのダメージが生じることを抑制する。 [解決手段]収容部を有する袋は、袋の内面に位置するシーラントフィルムと、シーラントフィルムよりも外面側に位置する少なくとも1つのプラスチックフィルムと、を含む積層体と、一対の積層体の内面同士を接合するシール部と、を備える。シール部は、袋の外縁に位置する外縁シール部と、外縁シール部よりも収容部の中心点側に位置し、収容部の圧力の増加により剥離する蒸気抜きシール部と、を有する。蒸気抜きシール部は、収容部の圧力が130kPa以下のときに剥離する。
