PRINTED THERMOPLASTIC FILM WITH RADIATION-CURED OVERPRINT VARNISH

A packaged food product includes a food product and a package enclosing the food product. The package may be formed from a coated, printed film that includes a substrate film including one or more thermoplastic materials and having an average thickness of less than about 15 mils. An image is printed...

Zusammenfassung:	A packaged food product includes a food product and a package enclosing the food product. The package may be formed from a coated, printed film that includes a substrate film including one or more thermoplastic materials and having an average thickness of less than about 15 mils. An image is printed on the print side of the substrate film. A radiation-cured varnish covers the printed image. The radiation-cured varnish was formed gy coasting the printe d image with a radiation-curable varnish that includes one or more polymerizab le reactants and optionally one or more photoinitiators. The radiation-curable varnish is subsequently exposed to radiation sufficient to polymerize at lea st 90 weight % of the polymerizable reactants. When the coated, printed film is tested according to the FDA migration test protocol, no more than 50 parts p er billion total of any of the polymerizable reactants and the optional photoinitiators migrate within 10 days at the 40~C from the coated, printed film into a food simulant of 95 weight % ethanol and 5 weight % water enclos ed within a test container formed from the coated, printed film so that the foo d simulant contacts the food side of the substrate film and the ratio of volum e of food simulant to surface area of coated, printed film is 10 milliliters p er square inch.
