Abstract
A barrier coating for paper and a method of making the coated paper using a wax coating composition containing an inorganic mineral filler is provided. The inorganic mineral filler imparts a viscosity to the wax coating composition similar to the viscosity of the wax coating composition in the absence of the inorganic mineral filler. Coated paper products are also provided.
