POLYOLEFIN FILM WITH BARRIER PROPERTY

摘要

PURPOSE: To obtain an oxygen-barrier polyolefin film useful for preventing food deterioration by oxygen. CONSTITUTION: This film is obtained by applying a water-based coating composition comprising a polyvinyl alcohol (A) and a water-based anchoring agent (B) in an A/B ratio of 99/1 to 80/20 to a surface of a polyolefin film, after the surface is treated or after it is treated and printed. A metal or an inorganic compound is vapor-deposited on this film to obtain a deposition-coated gas- barrier film.
