wherein the bag front wall and the bag rear wall are joined together in a region of their side edges and bottom edges, at least in sections, directly or via side walls and/or side folds and/or a bottom fold;
a lower bag end, closed when used, in the region of the bottom edges of the bag front wall and the bag rear wall, comprising:
a bag bottom, and
a closed upper bag portion opposite the bag bottom,
wherein at a closer distance from the closed upper bag portion than from the lower bag end, at least one bag opening is present in one portion of the bag front wall, and
