Abstract: A method of producing a high barrier packaging material including the steps of applying an aqueous dispersion of polyvinylidene chloride (PVdC) to a first film (1), drying the aqueous dispersion of PVdC to form a PVdC layer (5), applying a second film (3) to the PVdC layer side of the first film (1) and peeling off the first film (1), while the PVdC layer (5) adheres to the second film (3).

Abstract: A curtain coater for coating a substrate, comprising: a nozzle system for creating a curtain of at least one coating fluid dropping onto the substrate, a porous curtain guide structure, which has a guide surface for providing a lateral guiding action for the curtain, which cambers round convexly towards the curtain across a width extending beyond the thickness of the curtain measured transversely to the curtain, at least one cavity extending in the longitudinal direction of the curtain guide structure for an auxiliary fluid to be guided on the guide surface and a cavity wall surrounding the cavity, of which the curtain guide structure forms only a circumferential segment, and the circumferential segment bounding the cavity is a part of an external contour of the curtain guide structure extending about a longitudinal axis of the curtain structure.

Abstract: A device for applying a liquid coating material onto a moving web-shaped substrate material, comprising application rollers rotatably mounted in a roller frame and forming a NIP roller gap for dosing the coating material; and a supply chamber for the coating material, which is vertically arranged adjacent to the rollers.
