PROBLEM TO BE SOLVED: To provide a transparent gas barrier film which can keep a gas barrier property even under high humidity. SOLUTION: The transparent gas barrier film is obtained by applying and film-forming, on a transparent resin film, a silica sol solution prepared by using, as a main component, an alkoxysilane compound and a hydrophilic resin composition from 5 to 30% by mass thereto. The transparent gas barrier film is obtained, which is suitable for food packaging without lowering the gas barrier property even under high humidity. COPYRIGHT: (C)2004,JPO |
