Whiteness is provided by 3 factors: whiteners (which in Navigator’s case is Elemental Chlorine Free (ECF) bleach), by the quality of the filler (a chalk-like substance which fits between the wood fibers to add opacity, which is called PCC, or precipitated calcium carbonate), and by Optical Brightening Agents, which absorb light from part of the invisible spectrum (UV) and emit visible light in the blue/white range of the spectrum, resulting in a whiter paper.

Navigator’s filler (PCC) is produced on-site from pulp production by-products and provides higher quality and whiteness, along with cost reduction and efficiency.
