Calcium Carbonate Filler

Function: CaCO 3 is used as a filler for making bright, opaque paper at minimum cost. Calcium carbonate also keeps the pH in the alkaline range (unless controlled with "acid-tolerant" technology). The rosette form of PCC filler tends to produce a bulkier sheet of paper; when calendered it yields improved smoothness at given levels of caliper.
