A composite multi-layer barrier is produced by first vapor depositing a barrier under vacuum over a substrate of interest and then depositing an additional barrier at atmospheric pressure in a preferably thermoplastic layer. The resulting multi-layer barrier is then used to coat an article of interest in a lamination process wherein the thermoplastic layer is fused onto itself and the surface of the article. The vacuum-deposited barrier may consists of a first leveling polymer layer followed by an inorganic barrier material sputtered over the leveling layer and of an additional polymeric layer flash evaporated, deposited, and cured under vacuum. The thermoplastic polymeric layer is then deposited by extrusion, drawdown or roll coating at atmospheric pressure. The resulting multi-layer barrier may be stacked using the thermoplastic layer as bonding agent. Nano-particles may be included in the thermoplastic layer to improve the barrier properties of the structure. A desiccant material may also be included or added as a separate layer.
