4800mm Waste Paper Based Packaging Grades Machine
The corrugated paper machine represents advanced engineering specifically for packaging paper production from recycled fiber. This corrugated paper machine features independent top and layer forming systems that optimize sheet structure and printability. The comprehensive design of this corrugated paper machine includes carefully controlled consistency, retention, and dryness parameters. Every aspect of this corrugated paper machine is optimized for producing corrugated paper and paper bag grades that meet demanding packaging requirements. This corrugated paper machine delivers exceptional performance for mills focused on sustainable paper production.
The corrugated paper machine operates with top layer consistency of 0.35-0.5% achieving 45-60% retention, while bottom layer runs at 0.4-0.9% consistency with 60-75% retention. This corrugated paper machine achieves composite dryness of 10-12% at the forming roll, wire section exit dryness of ≥21%, and press section exit dryness of ≥50% for 80 g/m² grades. The corrugated paper machine maintains incoming sizing dryness at 92-93% and delivers finished paper at 92% dryness. Double-sided starch sizing of 3-5 g/m² at 10% concentration ensures optimal surface properties of this corrugated paper machine. With average transverse shrinkage of 3-4% and 10% slurry return rate, this corrugated paper machine delivers consistent dimensional stability and efficient fiber utilization.
