The invention relates to a production method of an antistatic cellulose nano-crystal packaging composite film. The method comprises the following steps: 1, preparing a cellulose nano-crystal suspension; and 2, producing the antistatic cellulose nano-crystal packaging composite film. The antistatic cellulose nano-crystal packaging composite film has the following advantages: 1, microcrystalline cellulose is adopted as a raw material and is hydrolyzed by sulfuric acid to make the microcrystalline cellulose have negatively electric surface groups to enhance the reaction activity and the adsorption ability of the microcrystalline cellulose, cellulose nano-crystals are adopted as a carrier, magnetic ferriferrous oxide nano-particles are ultrasonically mixed and are attached to the surfaces of the cellulose nano-crystals, and a magnetic field is applied to realize macroscopic orientation of the cellulose nano-crystals and improve the electricity conductivity of the composite film; 2, transparent antistatic film well combines the transparence and the electricity conduction property of films, so the composite film has unique performances, and has wide development and application prospect; and 3, the production method has the characteristics of simplicity, fastness, high practicality, large market potential and high potential added values.
