PURPOSE: To produce a composite film having a printing layer inside suitable for food wrapping preventing wrinkling while continuously by peeling off and then, laminating doubly polymerized films after the inversion thereof from the surface to back thereof.
CONSTITUTION: Doubly polymerized films (preferably, cylindrical inflation films folded clear of both end selvages) 1 and 2 are peeled off with two peeling rolls 5 and 6 and then, inverted from the surface to back thereof with two inversion rolls 7 and 8 so arranged to cross the films in the ongoing direction thereof. At this point, the films 1 and 2 are advanced to the roll clearance from outside the inversion rolls 7 and 8. The films thus inverted are laminated to obtain a desired film. When a printing layer 3 is used outside the film 1 and a film having an adhesive layer 4 outside the film 2, a film having a printing layer inside is obtained.
