| abstract | A producing method of coated box cardboard or kraft paperboard with low cost and the coated box cardboard or coated kraft paperboard produced using the method are disclosed. The method comprises steps of bottom coating with bottom coating material and surface coating with surface coating material on the recycled or unbleached box cardboard or the kraft paperboard. A double-layer or three-layer coating process is used. By means of the synergistic effect of the components in the coating layers and the different coating layers, the whitening efficiency of the optical brightening agent (OBA) in low-whiteness unbleached box cardboard is improved. The coating material is mainly composed of kaolin, carbonate, starch and latex adhesive etc. The amount of OBA is not higher than 1% of the total coating amount. The amount of titanium pigment is not higher than 5% of the total coating amount. The total coating amount of the coated box cardboard is not higher than 40g/m2, and the whiteness of the paper product is not lower than 76%. |
