Blister packaging multilayer resin films and blister packages of the invention achieve a lower oxygen permeability than possible heretofore.A blister packaging multilayer resin film of the invention is used to produce a blister package in which an item is sealed between a support substrate and the multilayer resin film, wherein the multilayer resin film includes an oxygen barrier layer that is arranged on a side of the multilayer resin film which side faces the support substrate, and a moisture proof layer that is arranged on a side of the oxygen barrier layer which side does not face the support substrate.
