Pilot trials at Valmet Paper Technology Center prior investment decision.
Valmet’s solution was a complete one that required only a very short downtime for implementation.
The quality of the new coating was good from the start, and optimum quality was achieved after just eight hours of operation of the new curtain coater.
A very uniform coating is obtained resulting in increased opacity and better coating smoothness. Applied coating color has been reduced from 36 g/m² to 32 g/m².
