    • PURPOSE: A tire inner-liner film is provided to have excellent sealability with a thin thickness, to reduce the weight of a tire, and to improve fuel efficiency. CONSTITUTION: A film for a tire inner-liner(7) comprises a polyamide-based resin; a substrate film layer which has a polyether-based segment of specific content, a polyamide-based segment, and a heat resistant; and an adhesive layer which includes a resorcinol-formalin-latex-based adhesive. A manufacturing method of the film comprises a step of forming a substrate film by melting and extruding the copolymer, polyamide-based resin, and a heat-resistant agent and forming a substrate film by melting and extruding the mixture; and a step of forming a latex-based adhesive-containing adhesive layer on at least one side of the substrate film layer.
