Abstract
The present invention provides a gas barrier film which has high gas barrier performance and excellent repeated reproducibility of the gas barrier performance. A gas barrier film of the present invention comprises three inorganic compound layers (layer [A], layer [B] and layer [C]) that are sequentially arranged in this order on at least one surface of a polymer film base. The layer [B] has a thickness of 0.2-20 nm and a density that is higher than those of the layer [A] and the layer [C].
Claims10
Gas barrier film comprising a polymer base film laminated, on at least one of the surfaces thereof, with a gas barrier layer, the gas barrier layer having a layer structure in which a layer [A], a layer [B], and a layer [C], in contact with each other, are stacked in this order on the polymer base film, the layer [A] and the layer [C] each having a density in the range of 2.0 to 9.0 g/cm3, and the layer [B] having a density that is in the range of 2.3 to 10.5 g/cm3 and higher than the densities of the layer [A] and layer [C] and having a thickness of 0.2 to 20 nm.
