FILM FOR A TYRE INNER LINER AND A PRODUCTION METHOD THEREFOR

This invention relates to a film for a tire inner liner, which includes a copolymer including a polyamide-based segment and 5 ˆ¼ 50 wt% of a polyether-based segment relative to the total weight of the film, and has a thickness 30 ˆ¼ 300 µ m, and to a method of manufacturing the film for a tire inner liner, including polymerizing a polyamide-based resin or its precursor with 5ˆ¼50 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.
