Abstract: A method and apparatus for making an inner packaging container, in which fiber components of a pulp slurry, which is prepared by dissolving or dispersing pulp, carbon fibers, and sparsely acetificated PVA fibers in water together with sizing agents and additives, are deposited to a desired thickness over a mold surface of a lower mold perforated with a number of pores and defined with a suction chamber, under the condition in which the lower mold is immersed in the pulp slurry, using a reduction of pressure occurring in the suction chamber, and molded into a desired shape by the lower mold along with an upper mold engaging with the lower mold, thereby forming a conductive packaging container having an integral structure.
