Zusammenfassung:To provide a pouch which can properly emit steam generated in a storage part to the outside.SOLUTION: A pouch includes: a surface film and a back film; a lower film positioned between the surface film and the back film in a folded back state at a fold-back part and positioned at a lower part of the pouch; a sealing part joining inner surfaces of the films together; a storage part surrounded by the sealing part and storing a content; and a first non-sealing part located near an upper part of the pouch and isolated from the storage part by a first side sealing part. The sealing part includes the first side sealing part, a second side sealing part, and a bottom sealing part. A value obtained by dividing a distance (L1) [mm] by an approximate volume (V1) [mm3] is 0.00007 [mm-2] or less. The distance (L1) is the shortest distance from a planar center point (C1) on the surface film that overlaps a center point of the storage part to an inner edge of an intermediate part of the first side sealing part.SELECTED DRAWING: Figure 1 【課題】収容部において発生した蒸気をパウチの外部に適切に排出できるパウチを提供する。【解決手段】パウチは、表面フィルム及び裏面フィルムと、折り返し部で折り返された状態で表面フィルムと裏面フィルムの間に位置し、パウチの下部に位置する下部フィルムと、フィルムの内面同士を接合するシール部と、シール部によって囲まれ、内容物を収容する収容部と、パウチの上部寄りに位置し、第1側部シール部によって収容部から隔離された第1非シール部と、を備える。シール部は、第1側部シール部と、第2側部シール部と、下部シール部と、を含む。距離(L1)〔mm〕を近似容積(V1)〔mm3〕で割った値が0.00007〔mm-2〕以下である。距離(L1)は、収容部の中心点に重なる表面フィルム上の平面中心点(C1)から第1側部シール部の中間部分の内縁までの最短距離である。【選択図】図1
