Germany, June 9 -- Voith has launched EcoCal HiBulk, a new calendering solution designed to help board producers reduce fiber consumption while maintaining surface quality and mechanical strength. The technology has been successfully tested under production conditions at a leading European papermaker and marks an important step forward in bulk-saving calendering. In board production, surface smoothness and bulk traditionally stand in direct conflict. Improving printability through calendering often leads to higher sheet compression and a loss of bending stiffness. EcoCal HiBulk addresses this challenge through targeted conditioning of the paper web prior to the calender nip, allowing surface properties to be improved without excessive compa...
