Abstract
A vapor deposition film comprises a substrate made of a plastic material, a primer layer made from a composition comprising a specific trifunctional organosilane or a hydrolysate of the organosilane, an acryl polyol and an isocyanate compound, and an inorganic oxide vapor deposition layer to a thickness of 5˜300 nm, formed by successive lamination on at least one side of the substrate. Also, packaging materials and packages which employ the film are provided.
