Ground Calcium Carbonate (GCC) is extensively used in the paper industry as a primary filler and coating pigment. It enhances the brightness, opacity, and smoothness of paper, resulting in higher-quality printing surfaces. GCC improves paper’s whiteness and printability while reducing production costs by replacing more expensive raw materials. Additionally, GCC contributes to better paper formation and strength, supporting both coated and uncoated paper grades. Its fine particle size and purity make it ideal for producing glossy, smooth papers used in magazines, books, and packaging.
