1. A process for the production of surface-finished, at least monoaxially stretched, thermoplastic films, characterized in that, before at least one stretching stage, surface finishing is carried out using slot knife coating systems in which the substances to be applied are delivered by a pump (2) to the applicator head in the form of a slot die (4) which is arranged in front of an applicator roll (5) for horizontal displacement towards said applicator roll, in that the material to be applied is transferred from the applicator head (4) to the surface of the applicator roll (5) to form a continuous film on the surface of the applicator roll, in that the applicator roll (5) is brought into contact with a take-over and laminating roll (7) which transfers the surface film to a continuous film (8) optionally stretched in the machine direction and in that the coated film is subsequently stretched without surface contact. |
