PURPOSE: Provided is a multi-laminated film, which is produced by laminating existing unoriented film into a thermoplastic resin, and thus shows an identical effect to oriented film. CONSTITUTION: The multi-laminated film is formed by laminating an adhesive resin(2) between unoriented films(1,3) such as PP(polypropylene) or PE(polyethylene), in top and lower surfaces, wherein the adhesive resin consists of 35% of ionomer resin, 20% of random copolymer, 20% polyester resin, 15% of polystyrene, and 10% of cosmonate resin or diatomaceous earth. The film is produced by laminating a resin film having identical effect to high quality oriented film by simple equipment and an easy method, and thus can be economically produced.
