Patent ID: 7063882

Claim:
A packaged food product comprising: a food product; a package enclosing the food product, the package comprising a coated, printed film comprising: a substrate film comprising one or more thermoplastic materials, the substrate film having a print side and an opposing food side and an average thickness of less than about 15 mils; an image printed on the print side of the substrate film; a radiation-cured varnish over the printed image, the radiation-cured varnish formed by: coating the printed image with a radiation-curable varnish comprising one or more polymerizable reactants and optionally one or more photointiators, wherein the radiation-curable varnish includes less than about 20% monofunctional monomer based on the weight of the radiation-curable varnish; and subsequently exposing the radiation-curable varnish to radiation sufficient to polymerize at least 90 weight % of the one or more polymerizable ractants; wherein when the coated, printed film is tested according to the FDA migration test protocol, no more than 50 parts per billion total of any of the polymerizable reactants and the optional photoinitiators migrate within 10 days at 40° C. from the coated, printed film into a food simulant selected from the group consisting of i) 95 weight % ethanol and 5 weight % water and ii) 5 weight % ethanol and 95 weight % water, the food simulant enclosed within a test container formed from the coated, printed film so that the food simulant contacts the food side of the substrate film and the ratio of volume of food simulant to surface area of coated, printed film is 10 milliliters per square inch.
