The invention relates to a processing technology for a double-faced antistatic coating film. A material film stretched through MDO firstly makes contact with a coating roller I through a guiding roller so that single face coating can be carried out, then, the material film makes contact with a coating roller II so that coating of the other face can be carried out, and finally TDO preheating stretching is carried out; the coating roller I and the coating roller II are gravure rollers, the horizontal center distance between the coating roller I and the coating roller II is 1/5-1/4 of the diameter of each coating roller, the diameter of each coating roller ranges from 300 mm to 350 mm, the coating roller diameter refers to the diameter of the coating roller I or the diameter of the coating roller II, and the diameter of the coating roller I is equal to the diameter of the coating roller II; and the rotating direction of the coating roller I and the rotating direction of the coating roller II are opposite to the material feeding direction of the material film, and the coating weight of the coating roller I and the coating weight of the coating roller II on the surface of the material film ranges from 3 g/m<2> to 6 g/m<2>. By means of the processing technology, the occurrence of winding bar shaking in the coating process can be effectively avoided, uniform coating of antistatic coating is achieved, and the finally obtained product is uniform in surface coating and has an excellent antistatic effect.
