Wet pressing in containerboard production

A key to higher energy efficiency, and often a significant enabler of a capacity increase, is optimal wet pressing performance. Increased nip dewatering improves drying capacity and increases sheet dryness, with a remarkable effect on energy costs.

For example, increasing post-press dryness by 1.5 percent unit means savings of approximately €1.3 million in drying energy costs (case linerboard 400,000t/a).
