    The use of minerals in paper production has long been known, kaolin and clay are the main raw materials used as fillers in paper production but the cost is high while calcium carbonate is abundant in nature. , the cost is lower but the whiteness is higher, in paper environment is usually acidic environment, using calcium carbonate changes into neutral environment becomes a good alkaline environment for paper production. 

    Because of its wide application, today calcium carbonate is the most important filler and coating agent in the papermaking process. Fillers and calcium carbonate coatings will have a higher whiteness, giving the paper more opacity, gloss and good printability at competitive prices.

    Calcium carbonate can be used in very large quantities, the amount of wood material can be reduced without affecting the durability of paper. Paper machines can operate at higher speeds and finish dry paper faster, these improvements save energy costs.

    CALCIUM CARBONATE AS A FILLER IN PAPER:

    Calcium carbonate is used as filler in writing paper, printing paper or packaging paper and cardboard, fillers in paper have advantages over non-filler types as follows: paper produced with a smooth surface, high brightness, luster, higher gloss and improved printing ability.

    CALCIUM CARBONATE AS A COATING AGENT IN PAPER:

    Coated means increasing the surface quality of paper and rigid paper, the large-scale coating process under the fiber structure layers will leave a uniform paper surface for better printing process.
