Abstract
A method for manufacturing a dual ovenable, repulpable coated cellulosic board for forming food containers includes: coating an aqueous-based acrylic polymer blend barrier basecoat on a first major side of a cellulosic board substrate; and coating an aqueous-based acrylic polymer blend barrier topcoat on the aqueous-based acrylic polymer blend barrier basecoat, wherein an oleophobicity of the aqueous-based acrylic polymer blend barrier basecoat is higher than an oleophobicity of the aqueous-based acrylic polymer blend barrier topcoat.
