Assume there is always some migration at ppm level but the rate would depend
on the nature of the packaging material, product composition, storage
conditions and time. I think that those waxes and polyethylene (if poly is
used for this purpose) of the interleave are amongts least harmful packaging
substances in direct contact with foods. Besides, if they approved for the
purpose in the USA, they will be in the CFR. But please do not speculate or
take chances but contact the respective supplier of any packaging material
for MSDS and other relevent documents to prove the package composition,
safety and approval by the regulatory for the purpose.

A client of mine uses cardboard cartons with a paraffin-wax based coating to freeze blocks of fish mince in a horizontal plate freezer. Does anyone know if there is any migration from this coating into frozen fish?
Similarly, is there any migration from the sheet plastic used for interleaving frozen at sea fish, including oil rich fish?
