Each outer film has side edges, a bottom and oblique edges lying between the side edges and the bottom edge. Pair of gusset films is disposed in a folded state between outer films and each has side and oblique edges. Side seals are provided by joining side edges of the outer films to the side edges of the gusset films. A bottom seal is provided by joining outer films along their bottom edges.
