It is intended to be used as the internal layer of corrugated board and is characterized by a surface distinctly rough to the touch. Fluting has a high stiffness and low absorption of glue.
B-0 and B-1 fluting grades are manufactured in accordance with GOST R 53206-2008 and TU No. 17.12.34-084-24086615-2020. The fluting paper produced by PCBK includes high yield pulp in its composition. High yield pulp is a pulp obtained by light chemical treatment of hardwood (birch).
The fluting’s physical and mechanical properties ensure stable quality under static and dynamic loads (during stockpiling, stacking, storage, etc.) and robustness of the flutes.
PCBK produces fluting with the following widths in mm: 1050, 1260, 1400, 1575, 1900, 2000, 2100, 2200, 2300.
