Zusammenfassung:A method for the production of a filter membrane (1), whereby as starting material for the membrane production, at least one filler (3) and, optionally, at least one additional aggregate are admixed into a polymer membrane material (2), whereby the membrane material (4) that has the filler (3), and optionally the additional aggregate, is extruded to form a polymer film (5) that is charged with the filler (3), and optionally, the additional aggregate, after which the polymer film (5) is then stretched in a particularly monoaxial and/or biaxial manner for pore formation.
