The present invention relates to a method of providing a packaged food product comprising printing a substrate with an aqueous printing ink composition, drying said ink composition to provide a printed substrate and packaging a food stuff with said printed substrate, wherein the method excludes printing or applying any layers over the dried ink composition, wherein the ink composition comprises water and polyester resin. The present invention also relates to use of an aqueous printing ink for printing on a substrate, wherein the printed substrate has less than 50 ppb migratable species when heated to temperatures in excess of 150 C., wherein the aqueous ink composition comprises water and polyester resin.
