Gravure Coaters

Pyradia offers a complete range of gravure coaters designed according to the highest quality standards for long life and easy maintenance. Based on coating and product characteristics, the ideal gravure coater configuration can be direct gravure, reverse gravure or offset gravure.

Gravure coating is one of the most common coating methods used in the printing, coating and packaging industry to apply a thin, uniform layer of coating onto a substrate, typically paper, film, or foil. This process is appreciated for its coating weight uniformity, in applying coatings such as lacquers, adhesives, barriers and other functional or decorative coatings.

The gravure coating process consist of filling the engraved surface of a roller with the coating material, by exposing it to a fluid bath, and then wiping the excess with a doctor blade. This can be done in a classic open pan arrangement or with an enclosed doctor blade chamber that can be pressurised or not. Selecting the ideal gravure roll engraving pattern, both for volume and geometry, is key for obtaining optimum results.

For direct gravure, the engraved roller comes in contact with the substrate and move in the same direction. In reverse gravure, it turns in the opposite direction of the substrate. For offset gravure, there is a transfer roller located between the gravure roll and substrate.

With over 50 years of experience, extensive process knowledge, modeling software and pilot equipment, Pyradia engineers will analyse your specifications and recommend the ideal production line configuration for optimal process efficiency.
