Method of increasing filler content in papermaking

Method of producing paper with a higher proportion of mineral particles of charge than would otherwise be possible, without expecting the loss of paper resistance. The method makes it possible to use a greater amount of filler particles by coating at least some of the filler particles with a material that prevents the filler materials from adhering to an additive that confers resistance. The additive for conferring resistance keeps the cellulose fibers tightly bonded together and is not wasted on the particles in the filler. The method is particularly effective when the charge particles are a mixture of PCC-GCC and citing the GCC particles are coated with the coating to prevent adhesion.
