Code Federal Regulation for OPV Shrink

Dear All

I found trouble to identify CFR number, How to get information CFR number for OPV shrink (Secondary Packaging Material)?

Is OPV shrink similar to PVC shrink?

Thanks

Your supplier needs to identify which plastics are used in the shrink film and provide a statement about FDA 21 CFR compliance.

OPV = Oriented Polyvinyl film?

PVC = Polyvinyl Chloride film.

PVC is listed in FDA 21 CFR
