摘要：
A gas barrier laminated film comprising a thermoplastic film having a polar group and a thin silicon oxide layer formed on the one side of the thermoplastic film in which the bond energy of silicon in the silicon oxide layer varies along the direction of the thickness of the layer and becomes large in the vicinity of the plastic film. It has a high level of gas barrier properties for steam and oxygen and is suitable for a variety of packaging materials.
