Method of Manufacturing Film for Tire

Abstract

A method of manufacturing a film for tire used in an air penetration preventing layer of a pneumatic tire, composed of a thermoplastic elastomer with an elastomer component dispersed within a thermoplastic resin includes performing heat treatment on the film for tire formed by inflation molding or cast molding in a state of being wound in a roll together with a liner material configured to regulate deformation of the film for tire, the heat treatment being at a heat treating temperature equal to or higher than a glass transition temperature of a resin with a highest glass transition temperature in the thermoplastic resin included in the film for tire.
