  • Publication number: 20100034928
    Abstract: The present invention relates to printed antifog films suitable for the packaging of food products having an improved ability to maintain their antifogging properties after being wound up into a roll and to the packages obtained therefrom. The films of the invention comprise an overprint varnish applied over the printed image on the antifog film, said overprint varnish comprising a vinylidene chloride polymer and a surfactant. The printed antifog film may be manufactured using conventional equipment by applying an overprint varnish in the final print station of the printing process.
