METHOD OF MANUFACTURING HOT-WATER RESISTANT GAS BARRIER FILM AND THE HOT-WATER RESISTANT GAS BARRIER FILM

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a gas barrier film and the gas barrier film by the manufacturing method improving interlayer adhesiveness without depending on oxygen-bonding while preventing amidating or nitriding of a functional group positioned on a surface of a base material.SOLUTION: The manufacturing method includes a plasma treatment process for applying plasma treatment to at least the uppermost surface of a base material film with a plurality of plastic films peelably laminated in advance in an environment of the atmospheric pressure of 0.1 Pa or more and 10 Pa or less under the introduction of inert gas, and a gas barrier layer laminating process for laminating a gas barrier layer having the gas barrier characteristics on the surface after applying the plasma treatment process.
