 While producing high-quality extrusion products like fibers and films serious demands are made on the plastic filtration. Here the filter has to ensure that even minute impurities are completely removed from the melt. In storing and handling of the granule a contamination of the melt with small particles like metal abrasion or dust etc. can not be ruled out. These result in the later product showing unacceptable losses of quality or even torn fibers or films. While producing high-quality extrusion products like fibers and films serious demands are made on the plastic filtration.

-With filtering of delicate plastics or with high quality requirements of the filter rate the residence time and the residence time distribution have to be kept as low as possible. In addition, only filter arrangements which use large filter areas in small housing volume can be considered [[en:grundlagenhandbuch:werkzeug#references|[Hen82]]]. These requirements can only be fulfilled by a concentric arranging of the filter elements in form of a discus (Disc-Filter). The filter elements are here stretched on perforated supports. Those allow for the filtered melt to flow to the filter housing's exit.+With filtering of delicate plastics or with high quality requirements of the filter rate the residence time and the residence time distribution have to be kept as low as possible.
