Raw material savings with latest headbox technology

New headbox technology enables raw material cost optimization at Dongil Wolsan PM1 in Korea as less starch is needed and worse quality raw materials, such as OCC waste, can be utilised without compromising strength properties.

Valmet's new OptiFlo headbox opens us new possibilities to develop our process and product. When starch is fed through Aqua layer 15% compression strength improvement is achieved, but needed amount of starch is almost 30% lower."
