Abstract: A gas barrier film includes a base material containing a polyethylene as a main resin component and an inorganic oxide layer formed on a first surface side of the base material. The birefringence AN of the first surface calculated based on measurement by a parallel Nicol rotation method is 0 or more and 0.007 or less, and the proportion of the polyethylene in the entire gas barrier film is 90 mass % or more.

Abstract: This multilayer body is provided with a base layer, an intermediate layer, a heat seal layer, a first adhesive layer that is provided between the base layer and the intermediate layer, and a second adhesive layer that is provided between the intermediate layer and the heat seal layer. The base layer, the intermediate layer, and the heat seal layer are configured to include polyethylene. In a case where the base layer is a stretched polyethylene film, the intermediate layer is an unstretched polyethylene film, and in a case where the intermediate layer is a stretched polyethylene film, the base layer is an unstretched polyethylene film. The proportion of polyethylene in the multilayer body is 90% by mass or more.
