An object of the present invention is to provide a film and a pouch having basic characteristics such as a strength and barrier properties and achieving good openability. A film (10) according to the present invention includes at least a sealant layer (11), the film is formed with a cut guide line (G), and the cut guide line includes an impression (11A) formed in a surface of the sealant layer. In a pouch (30), the films are superimposed in a state where the sealant layers face each other, and peripheral edge parts are heat-sealed. The cut guide line is placed extending across at least a position where heat seal is not performed.

To provide a container bag 34 that can be manufactured easily by folding a sheet material 1 precisely along a folding line 11B. The sheet material 1 is prepared by bonding two films 2 and 3 together in a predetermined pattern, and the sheet material 1 comprises a plurality of cells 16 formed between the two films 2 and 3 while being joined to one another to be filled with fluid. A trunk portion 17 to be filled with a content is formed by bonding overlapping layers of a peripheral edge 9A of the folded sheet material 1. A bottom portion 13 of the container bag 34 is folded inwardly toward the trunk portion 17 along the folding line 11B. A non-bonded section 14 in which the two films 2 and 3 are not bonded together is maintained linearly within the folding line 11B.

The present invention relates to a flexible container (10). In an embodiment, the flexible container includes a first flexible film (12) superimposed on an opposing second flexible film (14). The first flexible film and the second flexible film are sealed along a common peripheral edge (16) to form an inner container having a closed chamber. The first flexible film and the second flexible film each has an outermost layer comprising an ethylene-based polymer. Each outermost layer is a surface-treated layer having a surface energy from 33 mN/m to 36 mN/m. The flexible container includes a peel sleeve (22, 24) superimposed on each respective outermost layer and along the common peripheral edge. The flexible container includes a release material (26) located between the peel sleeve and each outermost layer along the common peripheral edge. The release material releasably attaches the peel sleeve to the inner container.
