The invention concerns a film based on a binary polymer composition having at least a first polymer and a second polymer. The film is oriented by extruding and stretching the film in at least the machine direction. The glass-transition temperature (Tg) of the first polymer is greater than the orientation temperature and the glass-transition temperature (Tg) of the second polymer is lower than the orientation temperature. Furthermore, a method and use related thereto are described.
