FBB construction

mechanical pulp is placed between layers of chemical pulp. Mechanical pulp may be stone-ground wood (GW), pressurized ground wood (PGW), thermo mechanical pulp (TMP) or chemi thermo mechanical pulp (CTMP). The top layer is bleached chemical pulp and the reverse layer may be bleached or unbleached chemical pulp. The top and reverse side may be coated with mineral pigments.

The combination of inner layers of mechanical pulp with outer layers of chemical pulp creates a strong and stiff sheet, taking advantage of the well-known I-beam phenomenon in physics. This is a low density material with high stiffness. Fully coated grades give excellent printing and visual impact. This is a virgin fibre paperboard with consistent purity for product safety.
