may be used as a component of laminate structures that are in compliance with applicable FDA food additive regulations, provided that:

  • the products are not the food-contact layer, and
  • the products are separated from the food by a 2 mil (0.051 mm) thick food-contact layer that is manufactured from material the FDA considers to be an effective functional barrier to migration.

Based on our inquiries to the FDA, examples of effective functional barriers to migration include:

  • aluminum foils
  • polyethyenes complying with 177.1520
  • polypropylenes complying with 177.1520
  • blends of complying poly-ethylene and polypropylene

There may also be other materials that have been determined to be effective barriers to migration. However, the FDA has not published a definitive list of such "barrier materials".
