PROBLEM TO BE SOLVED: To provide a tire inner liner film which shows uniform and excellent properties over all directions when applied to tires and is capable of securing excellent durability and anti-fatigue characteristics even during the tire production process and the automobile running process.SOLUTION: A tire inner liner film includes a base material film drawn or oriented in a first direction and undrawn in a second direction vertical to the first direction and keeps the first direction set in parallel with the axial direction of a tire molding drum for producing pneumatic tire with a tensile strength ratio of 1.1:1 to 2:1 in the first direction and the second direction of the base material film, where the first direction is the same as the lateral direction (TD) of the base material film, and the second direction is the same as the longitudinal direction (MD) of the base material film, and the length of the base material film is 1000 mm or more.SELECTED DRAWING: None
【課題】タイヤへの適用時、全方向にわたって均一かつ優れた物性を示し、タイヤの製造過程、自動車走行過程においても優れた耐久性及び耐疲労特性を確保することができるタイヤインナーライナー用フィルムを提供することを目的とする。【解決手段】第1方向に延伸又は配向し、第1方向に垂直な第2方向には未延伸状態の基材フィルムを含み、前記第1方向が空気入りタイヤ製造用タイヤ成形ドラムの軸方向と平行に設定され、前記基材フィルムの第1方向及び第2方向の引張強度比が1.1:1〜2:1であり、第1方向は、基材フィルムの横方向(TD)と同一であり、第2方向は、基材フィルムの縦方向(MD)と同一であり、前記基材フィルムの第2方向の長さが1000mm以上であるタイヤインナーライナー用フィルム。【選択図】なし
