Abstract: A pouch container and a pouch container packaging prevents oblique seals from turning back, thereby reducing risk of leakage from the pouch container. The pouch container packaging includes a pair of outer films disposed on front and back sides with a spout sandwiched at the top. 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. Oblique seals are provided by joining oblique edges of outer films to oblique edges of gusset films. At least a portion of an inner edge of each oblique seal is curved.
