Abstract: This disclosure relates to a film for a tire inner liner including a base film layer including a copolymer or a mixture of 50 wt % to 95 wt % of a polyamide-based resin and 5 wt % to 50 wt % of a polyether-based resin, and an adhesive layer including a resorcinol-formalin-latex (RFL)-based adhesive formed on at least one side of the base film layer, wherein a difference between a maximum thickness and an average thickness of the base film layer and a difference between a minimum thickness and the average thickness of the base film layer are respectively 6% or less of the base film, and a method for manufacturing the same. According to the present invention, an excellent gas barrier property may be achieved with a thin thickness, and thus the weight of a tire may become light and the mileage of automobiles may be improved, and as the inner liner film may have a uniform thickness, excellent forming stability and a tire having excellent durability may be provided.
