ABSTRACT:
The object is to provide a thin film having high barrier properties and high translucency with no safety and health problems, which is capable of suppressing degradation due to moisture, oxygen and carbon dioxide gas and degradation due to the diffusion of impurities such as alkali metals and alkali earth metals, a deposition apparatus of the thin film, and products coated with the thin film by the deposition apparatus. Another object is to provide an extended usable range of the products of an environmentally friendly biodegradable material and a prolonged quality preservation period. The feature is that a single layer or laminated layer of a layer expressed by AlNxOyor layer expressed by AlxNyis deposited (coated) over the inner surface of a packaging film. The single layer or laminated layer thereof has high translucency, being capable of enhancing the barrier properties against moisture, oxygen and carbon dioxide gas, the heat resisting properties, and the mechanical strength. When the biodegradable material is used for the packaging film, the usable range of the products can be extended and the quality preservation period can be prolonged as well.
