内面にする方法がある。 Composite films of various configurations are used as packaging materials for packaging various foods. When printing on such a composite film, one of the pre-printed constituent materials is incorporated in the process of composite processing of the composite film so that the printed layer is on the inner surface of the composite film to protect and protect the printed layer. It is usually done to enhance the aesthetic effect. As a method for manufacturing such a composite film having a printed layer on the inner surface, printing is applied to one outer surface of a double polymerized film, and after applying an adhesive to the other outer surface, the film is rolled while polymerized. There is a method in which the film is wound up, and then the outer end of the wound film is peeled off and the printed layer is placed on the inner surface while being rewound.
しかし、上記方法では、手間がかかり、連続的

存する。 The present invention has found a method capable of solving the above-mentioned drawbacks, and its gist is to peel off the double polymerized films 1 and 2 with two peeling rolls 5 and 6, and , 2 are advanced from the outside of the rolls into the roll gap of two reversing rolls 7 and 8 disposed intersectingly with respect to the traveling direction of the film, the front and back of each film is reversed, and then the films are laminated. A method of manufacturing a composite film is provided.
以下本発明を図面に基いて説明する。 The present invention will be explained below based on the drawings.

面活性化処理を行なつてもよい。 The above polymerized film is provided with a printing layer 3 on the outside of the film 1 and an adhesive layer 4 on the outside of the film 2, as shown in FIG. 2A. The printed layer 3 can be provided by a normal gravure printing method, and the adhesive layer 4 can be provided by a normal dry laminating adhesive using a roll coater or the like. Note that a surface activation treatment such as a corona treatment may be performed on the surface of the film before the above-mentioned printing layer or adhesive layer is provided.

つて、強固に積層することができる。 The films 1 and 2 are then peeled off vertically by peeling rolls 5 and 6. Peeling rolls 5, 6
is a drive roll whose rotation speed can be changed. The rotation speed may be determined depending on the final production speed of the composite film. The peeled films 1 and 2 are turned over by reversing rolls 7 and 8. The reversing rolls 7 and 8 are disposed vertically and parallel to each other at an angle of approximately 45° to the direction in which the film travels from the peeling rolls 5 and 6. The reversing roll is also a driving roll like the peeling roll. Film 1, 2
By advancing the film from the outside of the reversing roll into the roll gap, the front and back sides of the film can be reversed. Providing a large number of air holes in the reversing rolls 7 and 8 and discharging compressed air from the air holes to reduce the frictional resistance between the film and the rolls is effective in preventing wrinkles in the film. As shown in FIG. 2B, the film after inversion has a structure in which a printing layer and an adhesive layer are sandwiched between the inner surfaces, and can then be firmly laminated by heating or pressure bonding.

のである。 Since the present invention has the above-described configuration, it is possible to continuously and consistently produce a composite film having a printed layer inside it from the film manufacturing stage, and it is also a method that can prevent wrinkles etc. in the film. Therefore, it can be suitably used in the production of food packaging materials and the like.
