ASSESSMENT SAMPLE, MANUFACTURING METHOD THEREFOR, AND GAS BARRIER FILM ASSESSMENT METHOD USING THE ASSESSMENT SAMPLE

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable assessment sample of a simple structure, using two films with gas barrier films.;SOLUTION: The assessment sample is used in implementing a calcium method of assessing the gas barrier performance of a gas barrier film of a film with the gas barrier film on the basis of a state of corrosion of a calcium film growing on the surface of the gas barrier film. The assessment sample consists of a pair of films with interior layers of gas barrier films 9 and 13 facing each other, and has an outer peripheral edge where the films are closed together. A gap space is formed in the center of the interior of the films with the gas barrier films, and is filled with an inert gas. An assessment calcium film 10 is formed on the surface of the gas barrier film 9 of the gas barrier films 9 and 13 facing each other in the gas space.;COPYRIGHT: (C)2008,JPO&INPIT
