Abstract: A side-gusseted bag (1, 22) made of film is disclosed, having two main walls (6, 7) and side-gusseted walls (8 to 11; 23, 24) lying therebetween on the periphery; said side-gusseted walls can be folded flat into a V-shape parallel to a longitudinal direction between two main walls (6, 7) lying on top of one another. The main walls (6, 7) encompass, in a head region (2, 28), a grommet (4, 33) with two opposing fastening surfaces for the film and the two sides of the grommet (4, 33) are also directly connected with one another in a head joint (5, 32).

Abstract: A packaging container for at least two components to be mixed with each other has an outer container for a first component and at least one inner container for a second component arranged inside the outer container. The outer container and the inner container have container walls and at least one of the container walls is at least partially comprised of flexible plastic material. At least the outer container has at least one shape-defining sealed seam along one side. The inner container is openable by pressure application from the exterior of the outer container for mixing the first and second components within the packaging container. The outer container has an area provided for forming a removal opening. The inner container has outer dimensions that, when the outer container is opened, hinder the inner container from exiting to the exterior.
