1. A method for packaging a food product, said method comprising:
receiving at least one piece of packaging material in a packaging machine, said packaging material comprising a cellulose-based mid-layer, an inside layer arranged to face the food product, and an outside layer, wherein an ink-based print is provided on the outside layer;
curing the inside layer of the at least one piece of packaging material, wherein ink particles, released from the outside layer to the inside layer, are bound to the inside layer, thereby preventing the ink particles from being released into the food product;
forming the at least one piece of packaging material into packages; and
filling the packages with the food product.
