What are the restrictions with functional barriers and food packaging printing?

In a situation where a printer has an approved functional barrier between the surface to be printed and the food product, conventional water and solvent-based inks may be used for printing. To determine whether or not a functional barrier is of the quality needed to prevent ink migration, the FDA should be consulted. In addition to discussing functional barriers, the ink chemistry, application and end product use should be discussed and reviewed by the FDA prior to printing.
