"Valmet's new OptiFlo headbox with Aqua layering technology opens us new possibilities to develop our process and product. We have already seen the potential of the technology on how strength properties can be improved. Unlike with conventional technologies, a rapid starch feeding response can be measured when starch is fed through Aqua layer; in both cases 15% compression strength (RCT) improvement is achieved, but needed amount of starch is almost 30% lower with Aqua technology. Even in chemically challenging process conditions, the technology enables great results," Jin Doo Kim, Vice President, Dong Il Paper.

The Aqua layering technology is developed for the most challenging stratified solutions where layer purity is a key feature. It produces a perfect, disturbance free purely layered structure that boosts strength properties and enables the use of different furnish qualities, cheaper raw materials and functional additives between layers while giving flexibility to develop improved end products.
