If you buy food packaging and sell into Europe, one date matters more than any other right now: 12 August 2026. From that day, food-contact packaging placed on the EU market must meet the PPWR substance limits — and there is no grandfathering. Stock produced before the deadline still cannot be sold into the EU if it breaches them.

The harder part is documentation. Under the regulation, a supplier's written assurance that a material is PFAS-free no longer satisfies the requirement on its own. What buyers are expected to hold is test evidence and a Declaration of Conformity. Teams that treated this as a paperwork formality are now discovering it in the middle of a contract.

This article answers the practical question: if you source PPWR compliant plastic packaging, what exactly should you ask your supplier — and what should you have in hand before your next shipment leaves the factory?

What Actually Applies Since August 2026

Behind the regulatory language, four obligations matter to packaging buyers today.

PFAS limits: Measured PFAS may not be present above 25 ppb for any single PFAS, 250 ppb for the sum of measured PFAS, and 50 ppm for total fluorine including polymeric PFAS. In practice, the standard first screening test is total fluorine — if it comes back low, the substance restriction is generally satisfied.

Heavy metals: The long-standing cap carries over — lead, cadmium, mercury, and hexavalent chromium together must stay below 100 mg/kg.

Recyclability: All packaging must be recyclable from 2026, with graded performance thresholds arriving in 2030 (grade C or better) and tightening to grades A/B by 2038. Design decisions made now determine which grade your package earns later.

Recycled content: From 2030, contact-sensitive PET packaging must contain 30% post-consumer recycled material, other contact-sensitive plastics 10%, and other plastic packaging 35% — rising further by 2040.

Underneath all four sits a documentation duty: a Declaration of Conformity per packaging item, supported by technical documentation that importers and distributors must be able to present on request.

Why "Our Packaging Is Compliant" Is No Longer Enough

A verbal or email assurance cannot be audited. Market surveillance authorities work from documents, and so should you. The shift regulators have made is from trusting declarations to demanding evidence — certificates of analysis from accredited laboratories, tied to the specific packaging item.

There is also a market-by-market trap. A product that is legal to sell in one US state may exceed another state's threshold, and a package that cleared customs last year may not comply with the EU limits this year. If you distribute from a single warehouse across several markets, the safe planning assumption is the strictest applicable standard — not the average.

Eight Questions to Ask Your Packaging Supplier

This list is deliberately short. If a supplier can answer all eight with documents rather than adjectives, you are dealing with a partner who understands 2026.

1. What is the base material and exactly which additives, coatings, or colorants go into it? PFAS usually enters through a functional treatment rather than the polymer itself. Knowing the full formulation is what makes the compliance claim verifiable.

2. Can you provide a certificate of analysis from an accredited laboratory, for this specific item? Generic "our material is food grade" statements do not answer a PFAS threshold. Ask for total fluorine (and targeted PFAS where relevant), per packaging type.

3. Which markets is this packaging cleared for, and as of what date? Get this in writing so a US-legal item is never assumed to be EU-legal by default.

4. Will you issue a Declaration of Conformity and maintain the technical file? Someone in your supply chain must hold this and be able to produce it on request.

5. What are the food-contact and hygiene credentials of the manufacturing site? Material compliance is only half of it — the production environment must be auditable too.

6. Is the structure mono-material, and how does that affect its recyclability grade? Multi-material laminates, dark pigments, and non-detachable components are becoming commercial liabilities as recyclability thresholds approach. Material choice is covered in depth in our comparison of which plastic suits disposable food tray applications.

7. What recycled content can you document today, and what is the roadmap to 2030? If 30% recycled PET is not available for your format yet, you need a dated plan rather than a promise. Our guide to choosing between PET, RPET and recyclable blister packaging explains what is realistically achievable in food-contact applications.

8. Can you show me a sample of the exact material you plan to run? Evaluating a physical sample for thickness, clarity, and stiffness before production is the cheapest due diligence available — and standard sample programs make it easy to do.

Don't Assume Switching to Paper Solves the Problem

Fiber-based packaging is gaining share for good reasons — lighter EPR fees and consumer acceptance among them. But the PFAS restriction was written precisely because grease-resistant treatments on paper and molded fiber were a major historical source of those substances. A paper clamshell with the wrong coating can fail the very limit it was meant to escape.

The better question is not "paper or plastic" but "which material, for this food, in this market, with what evidence." For chilled display programmes, clear PET remains one of the most widely recycled and verifiable food-contact materials available — as our introduction to PET material explains. For hot-fill and microwave applications, CPET food containers deliver heat performance without compromising the compliance story.

Well-engineered plastics also have structural advantages worth weighing: exact-fit cavities protect the product during transport, which reduces food waste — increasingly part of the regulatory conversation too. Solutions such as BPA-free food-grade sealing trays and frozen food packaging built for commercial use are designed to hold that balance between performance and compliance.

What to Prepare Now for the 2030 Milestones

2026 is the compliance deadline; 2030 is the redesign deadline. The organisations that treat the next few years as a preparation window rather than a waiting period avoid costly emergency conversions later.

Review designs against recyclability now: Wall thickness, flange design, and mono-material construction determine the grade a package can earn. These choices matter in the context of broader sustainable thermoforming packaging trends, where material reduction and recyclability are engineered together rather than traded off.

Lock in a recycled-content path: Confirm what your supplier can document today and what they can deliver by 2030 for each format you buy. Availability varies by format and thickness, so this conversation needs to start early.

Test real products, not just materials: Seal integrity, shelf life, temperature resistance, and transport performance should be validated on the actual food. Development and testing services exist to close that gap between a material datasheet and a working package — a step that also underpins standards for safe export packing.

Build a documentation habit: Keep a file per packaging item containing the certificate of analysis, Declaration of Conformity, material specification, and revision history. That file is what protects you in an audit — and it is far easier to build as you go than to reconstruct under deadline pressure.

Frequently Asked Questions

Do plastic food containers contain PFAS?

Generally no — PFAS are most often used as grease and water repellents on paper and fiber packaging. Rigid PET and PP food packaging is not typically formulated with PFAS, but the only way to be certain for your specific item is a laboratory certificate of analysis for total fluorine.

Is a supplier declaration enough for EU market access?

No. The declaration requirements point to evidence: certificates of analysis from accredited laboratories plus technical documentation, submitted with a Declaration of Conformity per packaging item. Importers and distributors must be able to present this on request.

What happens to stock made before August 2026?

There is no grandfathering. Packaging manufactured before the deadline still cannot be placed on the EU market after it if it exceeds the substance limits. If you are holding inventory, verify it against documentation rather than assuming the production date protects it.

Should we switch from plastic to paper packaging?

Not automatically. Paper can reduce EPR fees and improve consumer perception, but coatings are where PFAS risk concentrates, and fiber packaging often has more complex end-of-life paths than mono-material PET or PP. Choose based on your food, market, and the evidence your supplier can actually produce.

How do we verify recycled content claims?

Ask for documentation tied to the specific item: material certificates, chain-of-custody or equivalent traceability records, and the recycled content ratio stated in the specification. Contracts should specify how the ratio is verified, not only what it is.

Compliance Is Now a Supplier Question, Not a Formality

The 2026 rules changed what "good packaging supplier" means. Price and lead time still matter, but the first question is now whether your material will remain legal in the markets where your customers sell — and whether your supplier can prove it with documents rather than assurances.

Ask the eight questions above, keep the answers on file, and start planning the 2030 recyclability and recycled-content requirements while there is still room to design rather than react.
