Gas barrier multilayer film and method for enhancing oxygen barrier property of gas barrier multilayer film

摘要

Having a gas barrier layer on the deposition surface of the metal deposition filmThe OD value of the metal deposited film is 1.7 or moreA gas barrier multilayer film wherein the oxygen barrier property of the gas barrier layer is 600A method of increasing the oxygen barrier property of a gas barrier multilayer film having a gas barrier layer on the deposition surface of the metal deposition film;The OD value of the metal deposited film is set to 1.7 or more.The method of increasing the oxygen barrier property in which the oxygen barrier property of the gas barrier layer is equal to or less than 600 (CC / m2. Sup. 2 ATM).
