Due to the high yield of chemical mechanical wood grinding pulp (85%~90%), the production cost is relatively low,
and the manufactured FBB also has a certain price advantage.
Cigarette card general use of single-side coating of FBB(yellow core white card) or SBS(white core white card) coating layer is
mainly to improve the printing of cigarette card, generally two or three scraper coating.
The FBB consists of three layers of pulp, with bleached sulfate wood pulp for the top and bottom layers,
and chemical machinery for the core layers.
