The invention relates to a bag with a bag body consisting of four bag walls, onto which two first wide bag walls lie on top of one another and two second narrower bag walls are each folded over congruently onto themselves to the center in a line along their longitudinal edges, and in which one end of the bag body is sealed by a bag floor and which forms a bag opening at the other end of the bag body; as well as an unsealed bag seal on a bag opening adjoining the bag body; in which the bag seal consists of two first sealing flaps respectively laid out on top of and adjoining the first bag walls, and two second sealing flaps adjoining the second bag walls, folded over respectively onto themselves at the center in a line with the fold of the second bag walls; and in which at the respective ends of the first sealing flaps first gussets, and at the ends of the second sealing flaps second gussets are specified, and directly adjacent first and second gussets lie respectively on top of one another with their inner surfaces and are glued or heat-sealed together to form double layered sealing corners. |
