Gas barrier laminated plastic material

PURPOSE:To provide a gas barrier laminated plastic material used as a packing material capable of being well heated in an electronic oven, capable of seeing content, capable of being recycled after use and easily subjected to disposal treatment. CONSTITUTION:A gas barrier laminated plastic material consists of a plastic material, a first layer formed out of a polymer of an organosilicon compd. containing at least silicon, oxygen and carbon provided on the plastic material and a second layer made of silicon oxide provided on the first layer. The first layer contains 15% or more of silicon and 20% or more of carbon in a compsn. of silicon, carbon and oxygen and the second layer is made of silicon oxide SiOX (X=1.5-2.0).
