PURPOSE: A method of manufacturing gunny bag coated with a volatile anti-corrosion resin, capable of the corrosion prevention of iron or non-ferrous metal contained in the bag, is provided to perform a biochemistry analysis when annulling the gunny bag. CONSTITUTION: A method of manufacturing gunny bag coated with a volatile anti-corrosion resin comprises sodium benzoate, sodium metasilicate, sodium molybdate and benzotriazole(S10). The mixture is shattered to be powdered(S20). The polyethylene resin and dispersing agent are mixed with the pulverized mixture in a temperature range of 140°C-160°C(S30). A second anti-rust resin is coated in the inner side of the gunny bag(S50).
