The present invention discloses a method for producing coated film, comprising the following procedures of: coating water-based macromolecular emulsion on the surface of a film substrate, drying the film substrate coated with emulsion with microwave, and then curing the dried film to make the coating crystallize homogeneously. The coated films produced with that method are tolerant to friction and are featured with strong resistance to scraping, high tensility, high contractility, excellent antistatic property, low surface friction factor, perfect glossiness, high oxygen and water obstruction property, and low production cost, and are especially suitable for producing high-performance thermal contracting coated films. The contracting films produced with the method may be used as esthetic and abrasion-resistant wrapping material and may help to extend quality guarantee period of articles.
