PROBLEM TO BE SOLVED: To specially treat and process a specific humic substance and add the substance to a stock for manufacturing a bacteriostatic container or material for preventing a food poisoning or a contamination of a living environment, and to impart its characteristics to a product.;SOLUTION: A method for manufacturing a strong bacteriostatic container utilizing characteristics of the humic substance or the material comprises the steps of strongly pressurizing a special humic substance blank matured while exposing with a direct sunshine in a house adopted in a specific production center and agitating, dissipating a moisture by a force of a pressurized heat of 100 to 150°C to an anhydrous state, and then processing the substance to ultrafine powder having a particle size of 3 to 5 microns. The powder is good drapable with a plastic or a paint. Even when the powder is injection molded or coated, the powder is integrated and diffused on a surface due to its substance characteristics, and hence the powder can hold a bacteriostatic function of the container or the material to contribute to a healthy life.;COPYRIGHT: (C)2002,JPO
