1. A gas-tight laminated plastic film material comprising:
- a plastic film;
a first layer formed over said plastic film and made of polymer of organosilicic compound containing more than 15% silicon element, more than 20% carbon element and the balance oxygen element, based on 100% of the silicon, carbon and oxygen elements; and
a second layer formed over said first layer and made of more than 60% silicon oxide expressed as SiOx wherein x is 1.5 to 2.0.
