The present invention relates to a method of manufacturing a film, and more particularly, to a method of manufacturing a multi-layer film having functions such as antistatic and buffering. In terms of its configuration, a film includes a foaming layer 1 for absorbing physical impact, which is interposed between layers, and a surface layer 3 having an antistatic function, which is installed at each of both surfaces. In relation to a method of manufacturing the film, the foaming layer 1 and the surface layer 3 are laminated when a liquid synthetic resin is in a molten state, and then, are extruded in one blow extruder, so that forming and laminating are simultaneously performed. |
