Valmet is launching two new calender roll covers to extend its roll cover selection. In the new Valmet Calender Roll Covers CL-W and CL-S, the highest wear resistance has been combined with the best load-speed durability and impact resistance. Due to the improvements in material technology, these covers give the longest regrinding intervals under the most difficult calendering conditions in soft and multinip calenders. In addition to graphical papers, they are suitable for specialty papers, as well as container and packaging boards.
