Bentonite is crucial to paper making, where it is used in pitch control (i.e. absorption of wood resins that tend to obstruct the machines), to improve the efficiency of the conversion of pulp into paper, and to improve the quality of the paper. Bentonite also offers useful de-inking properties for paper recycling. In addition, acid activated bentonite is used as the active component in the manufacture of carbonless copy paper.
