  • the weakening as predetermined breaking point which is advantageously centrically attached on an external wall side of the film bag and is produced, for example, under the action of light, can have an extension which is advantageously smaller than one half, one third, or one fourth of the extension of the external wall side on which the predetermined breaking point is located.
  • a position of the predetermined breaking point centered on the external wall of the film bag can facilitate the mechanical draining of the film bag under the action of pressure as it can thus be better ensured, for example, that the weakening or the predetermined breaking point, respectively, is located above the outlet opening of the draining chamber independent of rotations of the film bag in one plane.
  • non-centered positions of the predetermined breaking point on the external wall side of the film bag are also conceivable.
  • the film bag can have a rectangular shape and comprise at least one weld seam for closing the film bag after it has been filled, the weld seam/weld seams being resistant to pressures above the aforementioned pressure ranges leading to an opening of the predetermined breaking point.
