PFAS-Free Packaging Compliance FAQ for Molded Pulp Buyers

Data: The U.S. FDA administers the food-contact substances framework governing materials intended to contact food and the documentation supporting their use.

Judgment: Request the food-contact and chemical documentation per SKU, because a claim attached to a material family does not cover the additive package on the specific part placed on the market.

Data: The European Commission develops packaging and plastics policy covering material composition requirements placed on packaging on the EU market.

Judgment: Check the claim against the market of sale, because the applicable definition and threshold differ between jurisdictions and a single global declaration may satisfy none of them precisely.

Data: ASTM International maintains test methods that define sample preparation, test conditions and reporting for packaging materials.

Judgment: Require the test report to identify the sample by SKU and lot, because a result produced on a different part proves nothing about the product being placed on the market.

Where does PFAS enter molded pulp packaging?

Mainly through additives rather than the fiber: grease and moisture barrier coatings, some inks and dyes, and mold-release or processing aids. A molded pulp part is therefore not automatically PFAS-free because it is made from paper fiber. The answer depends on the additive package and the recycled fiber stream, which is why the claim should be verified against the actual SKU rather than accepted as a property of the material family.

What documentation should a buyer request?

A written declaration naming the regulatory definition and detection limit relied on, the SKU and revision it applies to, a test report from an accredited laboratory where the claim rests on testing, and the additive inventory for coatings, inks and processing aids. A general statement that a supplier is PFAS-free does not transfer responsibility away from the buyer, because regulators look to what was placed on the market.

How should testing and detection limits be specified?

Name the accredited laboratory, the analytical method, the numeric detection limit and the identity of the sample by SKU and lot. A result reported without a detection limit cannot support a claim of being free of a substance, because the claim only has meaning relative to a threshold. Keep the report with the declaration and make sure the tested sample is the part actually supplied.

Do PFAS definitions differ between markets?

Yes. The substances covered and the thresholds applied vary by jurisdiction, so a declaration written for one market may not satisfy another. Where packaging is sold into several markets, build the file around the strictest applicable definition, state the threshold explicitly, and keep any printed or advertised claim no broader than the documentation supporting it, since a printed claim is the easiest thing to challenge.

When must PFAS documentation be refreshed?

At every change to the specification, fiber source, coating or ink, and on a periodic cycle tied to the supplier's material changes rather than only to a contract anniversary. A declaration that applies to a component the supplier no longer uses is worse than no declaration because it creates false assurance. Tie the refresh obligation to a change-notification clause so the buyer hears about a substitution before it ships.

How does additive substitution create compliance risk?

A compliant product becomes non-compliant when a coating, ink, dye or processing aid is substituted without notice, because the declaration still describes the old chemistry. Require notice with a defined lead time and a re-declaration before the changed part ships, and treat undisclosed processing aids as a documentation gap rather than a technicality.
