In this work, we aimed to analyze suspensions of cationic starch by adding 5 wt%, 7 wt%, and 10 wt% of bentonite as a bilayer coating on kraftliner paper (85 g/m2). The controls were doubly-wet-and-dry and uncoated kraftliner paper. In a coating machine, the formulations were applied until reaching a grammage of 15 g/m2 and then dried at 103 ± 2 °C.

The reason is because bentonite significantly increased the pulp viscosities by increasing the shear stress and shear rate. Consequently, the bubble-particle collisions are reduced ( Wang et al., 2015 ) which can be attributed to the increased pulp viscosity and deteriorated froth stability ( Yu et al., 2017 ).
