SAICA El Burgo - new off-line coating machine
In 2018, SAICA’s new and innovative off-line coating machine was successfully started-up at its El Burgo mill. SAICA was aiming for improved quality, reduced costs, and responsible fiber use, but it found itself with innovative coated white top liner grades with a behavior completely different to the ones they wanted to replace. Using only brown fiber requires quite a lot from coating. The paper coated with Valmet's curtain coating station had better brightness, it was totally even, the lightness and intensity of the printing colors were outstanding. This was a result of three partners – SAICA, Valmet and pigment supplier Omya – joining forces.
The paper had better brightness. It was totally even.
But the most important property was the enhanced brightness of the paper, and the lightness and intensity of the printing colors. The colors appeared glossier. With standard white top testliners, you cannot control the three variables of whiteness. With this new way to produce the paper, we could control those with each parent roll."

SAICA wanted to
Pilot trials at Valmet Paper Technology Center were really important to find the best solution for SAICA.
