TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The multilayer film comprises multilayer portions which are laminated and adjoined. The articles are battery cells (11) which used connection portion as electrode terminal (13).    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The A-layer comprises polyamide-type resin, polyolefin resin, polyester-based resin, and polystyrene-type resin. The B-layer comprises resin having melting point lower than resin which comprises the A-layer. The resin layers comprises polycarbonate-type urethane resin as main component, and including resin layer provided in the side in which the film contacts the surface of the articles of multilayer film. The resin layers are printing layers which printed the urethane type ink which has a polycarbonate-type urethane emulsion as main component, and formed on the multilayer film. The film sticks on the surface of the articles by desecrating between the articles and the films from the upper surface side of the articles after heating and covering the softened film on the articles. The film has inner surface adhesive portion in which film inner surfaces closely adhered in portion which covers the upper surface of the articles. The B-layer is resin layer containing polyolefin resin as main component. The A-layer comprises resin layers having absorption factor of laser beam which is higher than the B-layer. Preferred Process: Manufacture of film-coated product involves irradiating laser beam to the film that covers the articles, and extending the film by deaeration and thin portion in which thickness became thin rather than the deaeration before at film portions is formed, and in which the laser beam is irradiated to the thin portion, and cut the film. The articles have portion (P1) and portion (P2) in which outer periphery length is shorter than portion (P2), and the film is stuck over the portions (P1) and (P2), and laser beam is irradiated to portion (P2) of the film, and disconnect the film.
