Embodiment 1
[0175]
[0176] Polyester-based films (manufactured by Teijin Corporation, "TR-8550T1", polyethylene terephthalate (PET)) as the first and third resin layers, and polyethylene-based films as the second resin layer Resin (manufactured by Nippon Polyethylene Co., Ltd., "Novatec LL UE320", low-density polyethylene (PE)) was supplied to three extruders respectively, and co-extruded so that the first resin layer / second resin layer / third resin The thickness ratio of the layers was 25:30:25, thereby forming a three-layer coextruded multilayer film (resin layer film) having a thickness of 80 μm. In addition, the resin layer film was prepared similarly to Example 1 based on the structure of Table 5 about the resin layer film in other Example and a comparative example.
