<p>PURPOSE:To enhance the adhesiveness of two layers by forming a metal film layer to a base film and continuously forming a coating layer to said metal film layer. CONSTITUTION:A base film 6 is fed out of an unwinder 1 and fed to a metal film forming apparatus 3 while the rear of said film 6 is subjected to corona discharge treatment by a corona discharge treatment apparatus 2. A metal film layer is formed to the rear of the film 6 under a vacuum atmosphere by the metal film forming apparatus 3 and this metal film laminated film 6A is subsequently reversed to be fed to a laminator 4 and the metal film is coated with the laminating resin flowing down from a die 53 to take up a desired multilayer film 6B by a winder 5.</p> |
