The surface paper is attached to the surface of the corrugating medium and the back side of the paper is attached to the back side of the corrugating medium. The printed paper is attached to the surface of the surface paper and the ceramic solution coated layer for the outer surface is attached to the surface of the printed paper. The ceramic solution coated layer for the inside surface is coated to the back side of the paper. In the surface of the ceramic solution coated layer, printing and after process is carried out to become the outside of the packing box.
