Abstract: The invention relates to a method for producing a biaxially oriented polypropylene film including at least one layer, which is constructed from propylene polymer B and a propylene polymer that has been recycled once. The method includes heat and melting propylene polymer B in a first extruder and heating a melting a propylene polymer A without a fraction of recycled material in a second extruder. The molten mass of the propylene polymer A is fed to two sides of the propylene polymer molten mass of B such that the propylene polymer A forms border regions of the film during the production process. The two border regions are then cut off after longitudinal and traverse stretching of the film, and melted and mixed together with the propylene polymer B and extruded to form a precursor film in the first extruder. The biaxially oriented polypropylene film comprising a propylene polymer that has been recycled only once is useful for producing capacitors.
