The evaluation method null plastic backing material of production condition of the gas barrier

摘要

PROBLEM TO BE SOLVED: To provide a gas barrier film laminate capable of confirming the presence or absence of the treatment to a base material even after the laminate is obtained when a gas barrier film is used as the laminate.;SOLUTION: The gas barrier film laminate is manufactured by laminating the inorganic oxide vapor deposition layer of the gas barrier film, which is obtained by providing the inorganic oxide vapor deposition layer (2) with a thickness of 5-100 nm at least on one side of a plastic base material (1), and another plastic film (5) by a dry lamination method. When this laminate is peeled while applying water to a peeling surface, peeling is caused in the surface of the base material (1) of the gas barrier film and, when the peeling surface on the side of the plastic film (5) is measured by X-ray photoelectron spectroscopy, the sum total ratio of the elements originating from the inorganic matter contained in the inorganic oxide vapor deposition layer detected from the peeling surface is 9.0 atomic% or below.;COPYRIGHT: (C)2008,JPO&INPIT
