To provide an inner liner having excellent gas barrier properties and flexibility, being also excellent in adhesive properties of a junction.SOLUTION: An inner liner comprises a multilayer structure including three or more gas barrier layers 21 and elastomer layers 22 alternately stacked, and adhesive layers 30 formed on both sides of the multilayer structure. The thickness T1 of the adhesive layer 30 is 0.3 to 2.5 times the thickness T2 of the multilayer structure. The thickness of the adhesive layer 30 is 3 to 200 μm, the thickness per layer of the gas barrier layer 21 is 0.001 to 10 μm, and the thickness per layer of the elastomer layer 22 is 0.001 to 40 μm.SELECTED DRAWING: Figure 1

    【課題】優れたガスバリア性及び耐屈曲性を有しつつ、接合部の接着性にも優れたインナーライナーを提供する。【解決手段】ガスバリア層21とエラストマー層22とを交互に3層以上積層した多層構造体、及び、該多層構造体の両面に形成された接着剤層30を備え、接着剤層30の厚さT1が、多層構造体の厚さT2の0.3〜2.5倍である。接着剤層30の厚さが、3〜200μmであり、ガスバリア層21の一層あたりの厚さが、0.001〜10μmであり、エラストマー層22の一層あたりの厚さが、0.001〜40μmである。【選択図】図1
