Abstract
The present invention relates to a film for a tire inner liner, particularly to a film for a tire inner liner including: a base film including a copolymer or a mixture of polyamide-based resin and a polyether-based resin; and an adhesive layer including a resorcinol-formalin-latex (RFL)-based adhesive, wherein the base film has a tensile recovery rate of 30% to 80%. The film for a tire inner liner of the present invention may exhibit an excellent gas barrier property with a thin thickness, and thus enables light weight of a tire and improvement in automobile mileage, and enables easier forming during a tire manufacturing process.
