  Disclosed is A gas barrier film comprising a substrate film and a barrier layer containing an organic region and an inorganic region on the substrate film, in which, when the organic region is provided on one surface of the gas barrier film, the outermost layer on the side with the organic region is an adhesive layer, or when the organic regions are provided on both surfaces of the gas barrier film, at least one outermost layer of the gas barrier film is an adhesive layer. The gas barrier film is capable of simplifying the working process with it and keeping its good gas-barrier property.

  本发明涉及一种气体阻隔薄膜，包括基材薄膜和位于基材薄膜上的含有有机区域和无机区域的阻隔层，其中，当有机区域位于气体阻隔薄膜的一侧时，有机区域所在侧的最外层为粘合层；或者当有机区域位于气体阻隔薄膜的两侧时，气体阻隔薄膜至少有一侧的最外层为粘合层。该气体阻隔薄膜能够简化使用过程并保持其良好的气体阻隔性能。
