Technology of Magnetron Deposition of Nanosized High-Barrier Relative Oxygen Aluminium Oxide Coating on Roll Pet Film

The paper introduces the development of the technology of reactive magnetron deposition of a nanosized aluminum oxide layer on a roll PET film, which provides a low specific permeability relative to oxygen. We describe a large-size magnetron deposition facility and its optimal operating modes, as well as the sequence of operations performed. Within the research, we found that various parameters of magnetron deposition of aluminum oxide affect the characteristics of the nanosized layer. The thicknesses of oxide layers were measured in the range of 20--80 nm, the roughness of their surfaces and their structures and reliefs were estimated. Furthermore, we established the experimental dependence of the specific permeability relative to the oxygen of the oxide layer on the PET substrate on its thickness in the range of 20--80 nm. The study gives its qualitative explanation and describes the specific energy consumption
