PROBLEM TO BE SOLVED: To provide a composite film for lamination having goog easy peelability, being excellent in all of anti-tearing strength, sagging resistance, and transparency, and to provide a laminated film.SOLUTION: The composite film is composed of an external layer, an intermediate layer, and an inner layer. The external layer includes at least one polyamide resin layer and at least one layer including a saponification product of an ethylene-vinyl acetate copolymer, the intermediate layer includes at least one polypropylene resin layer and one easy-to-peel layer, and the inner layer includes at least one polyethylene resin or one heat seal layer having heat-sealability with polypropylene. The thickness of the polypropylene resin layer is 30-80% of total film thickness. The composite film for lamination has the easy-to-peel layer containing a polypropylene resin as a main component, a tear strength (23°C), measured by the Elmendorf method, of 30 kg/cm or more, a haze of 10 or less, and a total thickness of 60 μm or less. |
