Food grade is not a property of a resin. Compliance belongs to one finished article, against one food type, one contact time and temperature, and one market. This page is about the evidence package to ask a supplier for: which document proves which claim, and the fields each must carry. It does not restate what the FDA, EU 10/2011 or LFGB rules say; see our food contact compliance basics.
A resin can be sold as food contact suitable while the moulded part is still non-compliant. Buy evidence against the finished article and its process.
Statements cover a compound from a named maker. Once moulded, welded or printed, the claim must follow the article.
Masterbatch, slip agents and stabilisers are part of the formulation. Ask for a statement covering your colour set.
Regrind, rework and cleaning agents sit inside the claim. Ask what regrind percentage the supplier will certify.
Suppliers often offer one document where several are needed. Each proves something different.
| Document | Proves | Falls short when |
|---|---|---|
| Compliance letter | Maker's statement | No test data attached |
| Test report | Composition screening | Conditions differ from use |
| Migration report | Simulant, time, heat | Wrong food or contact |
| Batch certificate | This lot matches | No link to the article |
| Supporting dossier | Assembled file set | Not updated after change |
Start from where the goods sell, then narrow by what touches the plastic and how.
The US, EU and German regimes ask for different files; passing one does not cover another. See our 21 CFR and EU 10/2011 guides.
Fatty, acidic and alcoholic foods extract differently, so a water simulant says little about oil. Name the food.
Hot filling, microwaving, freezing and long storage are separate cases. State time and temperature at the worst case.
A washed, reused part accumulates exposure. Say how many cycles it must survive.
The commonest gap. Ask for an article-level statement on finished-part letterhead.
Ambient testing is not evidence for hot fill. Have the supplier match simulant, time and temperature to your use.
US and EU goods need both files. The overlap is mapped in our compliance map.
Recycled input has its own authorisation path. Read how rPET is cleared in the EU.
Inks, coatings, labels and adhesives sit on the food-side surface. Ask for theirs too.
Asking after the first shipment is expensive. Name the documents in the enquiry and repeat them in the order.
State market, food type, contact conditions, colour and regrind. Ask which files the supplier will issue.
Tie the certificate to a lot number so a claim stays traceable.
New colour, additive, moulder or regrind ratio is a new question. Require a re-issue.
No. It covers the material as sold, not your finished part. Ask for an article-level statement naming colour and process; see migration testing.
Only if that colour is named in it. Otherwise request a re-issue covering pigment and carrier.
No. The dossiers are built differently and one does not substitute for the other. See what certification covers.
Yes, and the route depends on material and market. Start with the rPET process.
Choose on service conditions first, then collect evidence. Compare candidates under engineering plastics.
Building a food contact specification? Send market, food type, contact conditions, colour and regrind expectations to the plastic materials desk. Review applications, raise process questions with custom molding services, and see the example food grade ABS resin listing.
