TL;DR: Compliance documentation for thermoformed trays is not a post-production checkbox — it determines which markets your packaging can legally enter, and getting it wrong after tooling is cut costs real money.
For a related specification, compare Thermoformed Trays & Inserts — Troubleshooting & Failure Guide before finalising the packaging brief.
TL;DR: EU food-contact thermoforms must comply with EU 10/2011, which lists over 900 authorized substances and requires a migration test at 60°C for 10 days minimum before market entry.
Regulatory Frameworks by Market: What Actually Differs and Why It Matters #
The compliance requirements for thermoformed trays diverge significantly between the EU, US, and China — not just in substance lists, but in how compliance is demonstrated and who bears legal responsibility. Before we cut a single tool, we review the destination market with our clients using what we internally call the MRC-3 market readiness checklist, because the substrate choice, colorant package, and adhesive or coating selection all need to be locked before tooling.
| Requirement | EU (EU 10/2011 + PPWR) | US (FDA 21 CFR) | China (GB 4806 series) |
|---|---|---|---|
| Regulatory basis | EU 10/2011 positive list; PPWR for recycled content | 21 CFR 177 (polymers), 178 (additives) | GB 4806.1–4806.11 national food safety standards |
| Migration testing trigger | Mandatory for all food-contact plastics | Required only when new substance or condition of use is outside cleared specs | Mandatory for novel materials; spot-testing by customs |
| Substance positive list | ~900+ substances listed in Annex I | Cleared under specific regulation sections — no unified positive list | GB 9685 additive list + GB 4806.6 for plastics |
| Recycled content rules | PPWR mandates rPET targets from 2025 onward; contact layer restrictions apply | No federal recycled content mandate for food packaging | No current national mandate; provincial guidelines vary |
| Documentation required | Declaration of Compliance (DoC) + supporting test data | No mandated DoC format; GMP records and formulation files | GB/T test reports from CNAS-accredited lab required |
| Responsible party | Food Business Operator (FBO) or importer | Manufacturer or importer | First domestic importer or domestic manufacturer |
The table above reflects the regulatory state as of mid-2025. PPWR (Packaging and Packaging Waste Regulation) is being phased in with tighter timelines for single-use plastics, so EU-bound trays now need a recycled content roadmap as part of the commercial conversation, not just a compliance footnote.
Our position: for dual-market projects covering both the EU and US, we recommend designing to EU 10/2011 first. EU requirements are structurally more demanding — if the material stack passes EU migration testing, it almost always satisfies FDA 21 CFR 177 conditions too. The reverse is not reliably true.
Where Compliance Fails — And Why Most Failures Are Preventable #
The failure mode we see most often is not a prohibited substance — it is an undeclared processing aid.
Thermoforming processes use release agents, mold lubricants, and anti-static coatings to run efficiently. In our production environment we use food-contact-grade release agents on all tooling surfaces designated for food or pharma trays, but the risk is not just our materials. It is the polymer supplier’s full formulation. Under EU 10/2011 Article 3(1), migration into food must not exceed 10 mg/kg overall (OML) and specific migration limits (SMLs) apply to individual substances — some as low as 0.05 mg/kg for certain plasticizers. If a slip additive in the base resin is not on the Annex I positive list, the tray fails compliance regardless of how clean our process runs. We log every incoming resin lot against our polymer supplier’s Declaration of Compliance before it touches the thermoforming line.
The second failure mode is contact-time and temperature mismatch in migration testing. EU 10/2011 Annex V specifies simulant, time, and temperature conditions based on the intended food contact scenario. A tray designed for ambient dried goods uses simulant D2 (vegetable oil) at 40°C for 10 days — a very different test than one for hot-filled sauces, which requires 70°C for 2 hours followed by 40°C for 10 days. We have had clients present test certificates from their resin supplier that used the wrong test condition for their actual application. The material was fine; the test was wrong. That does not pass EU market entry, and it requires repeat testing at approximately 6–8 weeks calendar time.
The third failure mode is colorant selection. Many pigment concentrates that are commercially available and visually attractive are not on the EU 10/2011 or GB 9685 positive lists. Black masterbatch is a recurring issue — carbon black grades differ in PAH (polycyclic aromatic hydrocarbon) content, and some grades are restricted under REACH Annex XVII. We only approve colorant lots that arrive with a valid CoC and SML-compliant test data. This adds 3–5 working days to material qualification for new color developments, and that timeline is non-negotiable.
Do You Actually Need a Full DoC for Every SKU? #
Yes, if you are selling food-contact trays into the EU — the Declaration of Compliance is not optional.
Under EU 10/2011 Article 16, a written DoC must accompany each material or article placed on the market, with supporting documentation available for inspection. The DoC format is not standardized in the regulation, but the content requirements are specific: identity of the material, name and address of the manufacturer, migration test references, conditions of use, and the list of substances for which SML compliance was verified. For non-food applications — electronic component trays, cosmetic inserts, blister displays — the EU requirement does not apply, but REACH SVoC declarations under REACH Regulation (EC) No 1907/2006 Article 59 still cover substances of very high concern above 0.1% w/w.
For China-bound trays, the test reports must come from a CNAS-accredited laboratory. Reports from non-accredited labs are routinely rejected at Chinese customs, which we have observed across roughly 15 shipments reviewed during our supplier qualification audits in 2023.
Specification Notes for Brand Partners #
When you brief us on a thermoformed tray project, the first questions we need answered are the destination market and the contact substance — whether that is food, cosmetic, pharmaceutical, or non-contact. Those two inputs determine the entire compliance pathway before we discuss material or tool design.
The gap we encounter most often in incoming briefs is the contact scenario: specifically, filling temperature and shelf-life duration. A tray holding ambient confectionery and a tray holding hot-filled sauces at 85°C use different simulant conditions under EU 10/2011 Annex V, and if that information is not in the brief, we default to the more conservative condition — which may require a thicker gauge or a higher-Tg material grade than the cost estimate assumed.
Our standard compliance documentation package (DoC, migration test report, resin CoC, colorant CoC) takes 15–20 working days to compile for a new material combination. If you are reusing an already-qualified substrate for a new tray geometry, that drops to 5–7 working days because the underlying material data is already on file. Sampling lead time runs 18–25 working days from tool approval, depending on tray complexity and whether the material stack requires new migration testing.
Frequently Asked Questions #
What is the minimum migration test data we need to sell thermoformed trays in the EU?
You need test data demonstrating compliance with the Overall Migration Limit of 10 mg/kg under EU 10/2011 Annex V, plus SML compliance for any restricted substances present in your material formulation — and all of this must be referenced in a written Declaration of Compliance that follows you through the supply chain. The test must use the correct food simulant and conditions for your specific contact application.
Does FDA 21 CFR compliance automatically cover the EU market?
It depends on the substance and use condition. FDA 21 CFR 177.1630 (polypropylene) and 177.1520 (polyolefin) clear many common polymers, but they do not cover every additive, colorant, and processing aid present in a commercial resin formulation. EU 10/2011 operates on a positive-list model, meaning anything not listed is presumed non-compliant — FDA does not work that way. Designing to EU 10/2011 from the start is the lower-risk path for dual-market projects.
How does PPWR affect our rPET tray project starting in 2026?
PPWR sets minimum recycled content targets for plastic packaging, with contact-sensitive applications like food trays subject to derogations until sufficient food-grade rPET supply is demonstrated. The regulation is being phased in through delegated acts, so the exact target percentages for specific tray types are still being finalized. Our current approach for EU-bound rPET trays is to qualify the recycled content at the resin lot level against EU 10/2011 compliance for recycled plastics and maintain lot traceability records, so any future audit can demonstrate chain of compliance from pellet to finished tray.
What documentation should we request from our resin supplier before production begins?
At minimum: a Declaration of Compliance specific to the resin grade (not the polymer family), a full additive and colorant disclosure with CAS numbers, migration test reports for the relevant simulants, and an ECHA REACH SVHC declaration. For colored compounds, a separate colorant CoC with SML data is required. If any of these are missing, we flag the lot under our MRC-3 checklist and the material does not enter the production schedule until documentation is complete.
