In order to improve the barrier property of the biaxially oriented polypropylene (BOPP) film, the PVA/SiO2 organic-inorganic hybrid coating on BOPP film was prepared by the sol–gel method. And the structure and properties of the hybrid composite films were characterized. The results showed that, the oxygen barrier property of the composite films was enhanced with the increase of PVA content, while the water vapor barrier property of the composite films was dropped. As the mass ratio of PVA increased to 80%, the oxygen barrier property of the composite films was 308 times that of the pure BOPP film, however, water vapor barrier character was half of the BOPP film.
