Fine laminar barrier protective layer
First Claim
1. A coated substrate defined by a coating having a multiplicity of consecutive individual layers respectively of a kind differing from or similar to a neighboring individual layer, the individual layers exhibiting a layer thickness of respectively at most 50 nanometers, wherein the substrate is a tube that is hot pinched after coating with the formation of a sealed cavity, wherein the coating comprises at least one partial layer packet having individual lavers of the same composition but different morphology.
