ABSTRACT:
The invention relates to a process for manufacturing a flexible film-type laminate (7) from two or more films (9a,9b) for packaging materials, whereby at least two films (9a,9b) are laminated to each other to give a film-type laminate and the film or film-type laminate is printed on, and at least one free surface of the film-type laminate is provided with a sealing lacquer coating (14). The invention is characterized in that the lamination (12), the printing (12) and the coating (14) of the film or film-type laminate with a sealant lacquer take place in-line at individual coating stations (1, 2, 4) in a production device (10) using an electrostatic coating process in which coating particles are electrostatically charged and deposited on the film surface to be coated using transfer means by applying an electric field, and melted and/or cured to give a coating film.
