Gas-barrier material

The invention relates to novel gas-barrier materials for food packaging, based on transparent nanosized hybrid organic/inorganic films on polymer substrates. By contrast with current brittle oxides, these new materials combine extremely high cohesive strength (with a corresponding crack onset strain larger than 5%) and considerably improved barrier properties (oxygen transmission rates lower than 1 cm3(STP)/m2/day/bar).
