Abstract
A printed antifog packaging film incorporates a cured reactive ink system or a cured reactive varnish system. The reactive ink system includes a radiation-cured ink or a cured thermoset ink. The reactive varnish system includes a radiation-cured varnish or a cured thermoset varnish. The cured reactive ink or varnish reduces the tendency of the antifog film to form a ghost condensate image of the printed image after the film has been unwound from a roll form and subjected to conditions that form moisture condensation on the film.
Claims77
A packaging film comprising:
- an antifog film;
- and
- a printed image on the antifog film, the image comprising an electron-beam cured ink.
A packaging film comprising:
- an antifog film;
- a printed image on at least one side of the antifog film;
- and
- an overprint varnish on at least a substantial portion of the printed image, the overprint varnish comprising an electron-beam cured varnish.
A packaging film comprising:
- an antifog film;
- and
- a printed image on at least one side of the antifog film;
- and
- an electron-beam curable overprint varnish on at least a substantial portion of the printed image.
A method of reducing the tendency of ghosting in an antifog film, the method comprising:
- printing an image on a side of an antifog film to form a print side of the film and an opposing side of the film;
- applying an electron-beam curable overprint varnish over a substantial portion of the printed image;
- subsequently curing the varnish by exposing the electron-beam curable varnish to electron-beam radiation;
- subsequently winding the antifog film to form a roll;
- subsequently unwinding at least a portion of the antifog film from the roll and exposing the portion of the film to conditions that form a moisture condensate on the opposing side of the film.
