  • Publication number: 20100255326
    Abstract: A method is provided for enhancing the gas barrier properties of substrates such as materials used in packaging, by applying a composition comprising a vinyl alcohol/vinyl amide copolymer, a cross linker and, optionally, a diacrylate or other polyacrylate and a photo initiator to the material and curing the composition by irradiation with UV light, visible light, IR irradiation and/or electron beam or by exposure to heat. The method includes the optional step of subjecting the material to a low-temperature plasma discharge or a corona discharge prior to applying the composition. The method provides, for example, packaging materials, such as, flexible packaging materials such as plastic films producing packaging materials with excellent gas barrier properties, for example oxygen barrier properties, which are readily printed upon.
