Abstract
A process for coating the surface of bodies fabricated from polymeric materials with inorganic films by depositing on the polymeric bodies a thin layer obtained by thermal evaporation, under vacuum, of glass/silicon mixtures. The process provides for improved control of surface-depending properties, such as wettability, haze resistance, gas and weight barrier properties and selective absorption of ultraviolet light.
