= METHOD FOR PRODUCING A FILM FOR A CARD-SHAPED DATA CARRIER, FILM AND CARD-SHAPED DATA CARRIER =

'''Abstract''':
a method for producing a film for a card-shaped data carrier, includes the following steps: providing at least one first material in an extruder of an extrusion apparatus; heating the first material to form a melt; extruding the melt through a nozzle outlet gap of the extrusion apparatus; conveying the extruded melt on a roller arrangement that is adjacent to the nozzle outlet gap and includes at least one cooling roller; providing at least one transfer film; supplying the transfer film to the extruded melt on the cooling roller is so the security element contacts a surface of the extruded melt on the surface of the transfer film; transferring the security element from the surface of the transfer film onto the surface of the extruded melt; cooling the extruded melt comprising the security element to form the film.
