Curtain Coating Applications

Curtain Coating Applications in the Paper Industry

Curtain coating in the slide (single- and multi-layer) or slot (single-layer only) format is being increasingly used for special paper coatings because of its capabilities: copious simultaneous layers, high coating speed and large die-to-web clearance. The advantages of the pre-metered methods associated with simultaneous multi-layer application yield a more accurate and uniform coating weight, with fresher and cleaner coated liquids. These advantages lead to big savings in production costs because of less coating colour consumption, less production runs due to multi-layer capability and less machine stops due to web breaks – and in the end to higher efficiency compared to the established coating methods.
