Abstract
The present invention provides a gas barrier film including a plastic film and a thin film which is made of a composition containing an oxide as a main component and is formed on at least one surface of the plastic film. A specific gravity of the thin film is 55% or more and 100% or less of a specific gravity of the oxide in the form of a crystal generally present at room temperature and under atmospheric pressure. Thus, the invention provides a gas barrier film having an excellent gas barrier and retort properties and bending resistance; a gas barrier film suitably used in a wrapping material for dried food, liquid food or food containing liquids, frozen food and retort food; a gas barrier film that can be used in an electronic oven, can be sterilized by micro waves end can contain a free-oxygen absorber; a gas barrier film suitably used in a paper carton, a tube, a lid and the like; and a gas barrier film suitably used for cutting off gas for industrial use.
