The present invention relates to a film for an inner liner for a tire, and to a method for manufacturing same, wherein the film comprises: a base film layer including a copolymer or a mixture of 50 to 95 wt % of a polyamide-based resin and 5 to 50 wt % of a polyether-based resin; and an adhesive layer which is formed on at least one side of the base film layer, and which includes a resorcinol-formalin-latex (RFL)-based adhesive, wherein the difference between the maximum thickness and the average thickness of the base film layer and the difference between the minimum thickness and the average thickness of the base layer is 6% or less of the average thickness of said layers, respectively. According to the present invention, superior air-tightness can be achieved with a thin film for a tire inner liner, thus enabling lightweight tires and improved fuel efficiency of a vehicle to be achieved. Further, the film for an inner liner for a tire has a uniform thickness so as to achieve superior molding stability and to thus provide a tire having excellent durability. |
