In the arrangement, the lower film (12) is moved continuously or intermittently horizontally from a deep-drawing unit (1) to a unit (2) for final sealing. - The upper film (8) is controlled by guides (14,14A) so that it moves against and parallel with the lower film. Gas is blown in by special components (7B) between the film strips, and sealing components (7B) seal the strip edges of the films. Final sealing involves at least one transversal seal. |
