This invention relates to a film for a tire inner liner, which includes a copolymer including a polyamide-based segment and 5˜50 wt % of a polyether-based segment relative to the total weight of the film, and has a thickness 30˜300μm, and to a method of manufacturing the film for a tire inner liner, including polymerizing a polyamide-based resin or its precursor with 5˜50 wt % of a polyether-based resin relative to the total weight of the film, thus preparing a copolymer, and melting and extruding the copolymer, thus forming a film.
