(57) [Summary] [Structure] A crystal of an α-olefin and a non-conjugated diene, wherein the concentration of the constitutional unit based on the non-conjugated diene in the copolymer is 0.05 to 20 mol%. An olefin resin molded product having a gas barrier property, in which an inorganic oxide thin film is formed on the surface of a molded product of a hydrophilic olefin copolymer. [Effect] The molded product of the crystalline olefin copolymer on which the inorganic oxide is vapor-deposited according to the present invention is a resin molded product whose gas barrier property is not deteriorated even when heat or force is applied during secondary processing or during use. Therefore, it is useful as a retort pouch packaging material and an IC packaging material. |
