PROBLEM TO BE SOLVED: To provide a light shielding barrier wrapping material comprising a metal-tone printing layer high in agglomeration force and hardly undergoing blocking and having a metal-tone brightness and a light shielding property. SOLUTION: The laminated body is constituted by sequentially laminating a metal tone print layer, and a light shielding sealant layer made of a film made by adding a shielding agent and 1-500 ppm of stripping agent to a base film on a gas barrier coating layer face of a transparent gas barrier film made by laminating a vapor deposition thin film layer composed of silicon oxide, aluminum oxide or an inorganic oxide obtained by mixing these on at least one face of a transparent substrate layer. The metal-tone print layer is composed either of an ink coating film obtained by mixing a blocking preventive agent made of surface-treated aluminum metal powder and inorganic powder for improving adhesiveness with a binder resin, or of a reactive ink coating film having an isocyanate compound added to the ink.
