  • paper or filter paper it is meant (conventional) wet laid paper which is excluded in the definition of nonwoven fabric.
  • the vacuum cleaner filter bag may be formed in the form of a flat bag.
  • the vacuum cleaner filter bag then includes none Block bottom.
  • a vacuum bag filter bag in the form of a flat bag comprises an upper and a lower, in particular rectangular, piece of filter material, which are connected to each other along the edge superimposed; This results in a seam along the circumference, for example in the form of an adhesive or weld seam. For example, therefore, the filter materials along the edge to be welded together.
  • the material layer may be formed such that its width corresponds to the length of a side edge of the flat bag.
  • the material layer may in particular have 50%, preferably 70%, of a side surface in the interior of the vacuum cleaner filter bag.
  • the material layer is preferably connected at the three side edges and / or at the fourth side edge with the piece of filter material in which the inlet opening is formed.
  • an inlet opening for an air flow is provided.
  • a holding plate 3 is fixed in the region of the inlet opening.
