PROCESS FOR DEPOSITING A GAS BARRIER COATING ON A POLYMER FILM OR POLYMER CONTAINER, AND POLYMER FILM OR POLYMER CONTAINER WITH COATED WITH SUCH A GAS BARRIER

摘要

A polymer film or polymer container coated with a gas barrier coating, wherein said gas barrier coating comprises a first layer of hydrogenated amorphous silicon nitride deposited onto said polymer film or polymer container, and a second layer of hydrogenated amorphous carbon deposited onto said hydrogenated amorphous silicon nitride layer, and wherein said gas barrier coating has a thickness of between 2 nm and 25 nm, preferably between 2 nm and 20 nm and still more preferably between 2 nm and 15 nm, with the proviso that said polymer container is not a polyolefin container.
