  • Method of making a vessel having a wall surface having a barrier coating
    Patent number: 5900285
    Abstract: A plastic vessel has a barrier coating comprising sequentially arranged barrier layers of organic polymer and of inorganic oxides, nitrides or oxynitrides. The barrier coating preferably has at least two inorganic barrier layers. The thickness of the inorganic barrier layers lies between 2 and 300 nm and the thickness of the organic barrier layer lies between 2 and 1000 nm. The total thickness of the layer packet should not exceed 0.1 mm.
