Food-Contact Label Material: The Compliance Documents That Actually Exist, and What They Do Not Cover

Food-contact compliance is the part of label material sourcing where the gap between what buyers think they have and what they actually have is widest. The documents exist. They are real, they are issued by named bodies, and they are frequently misunderstood — because the thing a supplier certifies is almost never the thing the buyer assumes is certified.

This article sets out the actual regulatory architecture, the documents that flow through the supply chain, and the four questions that separate a genuine compliance position from a marketing claim. It is written by a material supplier, so read the conflict-of-interest disclosure at the end.

First, the distinction that matters most

Almost every problem in this area comes from one conflation: the adhesive is not the article.

Migration limits under both the EU and US frameworks are assessed at the food-contact surface of the finished article. A declaration that a raw adhesive complies with a positive list says nothing about whether the finished laminate — adhesive plus facestock plus topcoat plus primer plus the ink your converter applies on top — stays within the overall migration limit in service.

An adhesive can be fully compliant on its own positive-list status and still contribute to a laminate that exceeds the overall migration limit once combined with everything else in the construction. This is why regulatory testing laboratories run simulant migration studies on representative production samples of the actual multilayer structure, using the food types and the storage or process conditions the packaging is intended for.

So when a label material supplier says "food-contact compliant," the useful follow-up is not "can I see the certificate?" It is "compliant how, and on what?" The three possible answers are very different in value:

The regulatory architecture, by jurisdiction

European Union

• Regulation (EC) No 1935/2004 — the framework regulation. Article 3 sets the general safety requirement: materials must not transfer constituents to food in quantities that endanger health, cause an unacceptable change in composition, or deteriorate organoleptic properties. Under Article 16, this obligation runs along the whole supply chain, and it is the legal basis for the Declaration of Compliance.
• Regulation (EU) No 10/2011 — the plastics regulation. It establishes the Union list of authorised substances and the specific migration limits (SMLs) for plastic materials and articles. It is the reference point most label constructions are assessed against, and it is the regulation most commonly named on a DoC.
• Regulation (EC) No 2023/2006 — good manufacturing practice for materials and articles intended to come into contact with food.
• Council of Europe Resolution ResAP(2004)5 — the resolution on adhesives for food-contact materials. It is a resolution rather than binding EU law, but it is widely referenced in adhesive compliance dossiers and in national implementations.

One mechanism worth understanding because it changes what is possible: the functional barrier. If a layer in the construction is thick and impermeable enough to keep migration of a substance behind it below the EU detection threshold of 0.01 mg/kg — provided the substance is not carcinogenic, mutagenic or reprotoxic — then raw materials that are not individually on the Union list can sometimes still be used, because the barrier is doing the protecting.

If there is no such barrier and the adhesive sits directly on the food-contact surface, every component must independently clear the applicable positive list. That is a materially higher bar, and it is why the same adhesive can be acceptable in one construction and not in another.

United States

• 21 CFR 175.105 — Adhesives. The general-purpose regulation for adhesive components in food packaging where the adhesive is not intended to contact food directly, typically because a functional barrier separates it.
• 21 CFR 175.125 — Pressure-sensitive adhesives. A separate, narrower listing specifically for PSA formulations such as those used on food-container labels, with its own positive list and conditions of use.
• 21 CFR 175.300 — Resinous and polymeric coatings, relevant to topcoats.
• 21 CFR 176.170 — Components of paper and paperboard in contact with aqueous and fatty foods.

A formulator working with both laminating chemistry and label PSAs has to check compliance against the relevant sections independently. Clearance under 175.105 does not extend to 175.125. And a raw material cleared under one framework has no automatic standing under the other: the EU Union list and the FDA positive lists were built from different data submissions and do not mirror each other substance for substance. Suppliers selling into both markets typically maintain two parallel dossiers, and the fact that they do tells you something about the products that only claim one.

Germany

Not EU law, but heavily referenced by European converters, and often the answer to "which standard is this declared against."

• BfR Recommendation XIV — Polymer dispersions, the reference for many water-based adhesives.
• BfR Recommendation XXXVI — Paper and board for food contact.

China

GB 9685-2016, with adhesives listed in Table A.5 (and coatings in A.2, inks in A.4). If you are sourcing from China and your destination requires a GB-based statement, the table reference is the specific thing to ask for — not simply "GB 9685."

The Gulf

Worth understanding because the standards are deliberately aligned with Europe. GSO 1863/2013 on plastic food-contact materials was designed to mirror EU 10/2011, and GSO 2231/2012 sets general requirements for all food-contact materials, closely reflecting the principles of EU 1935/2004. Practically, this means a construction already properly documented against EU 10/2011 for the relevant conditions is in a strong starting position for GCC food-contact compliance — which is a useful thing to know before you pay for a duplicate test programme.

The document chain, and who issues what

A Declaration of Compliance is not a certificate issued by a regulator. It is a document issued by a supplier in the chain, confirming that the material or article meets applicable food-contact law. The obligation comes from Article 16 of Regulation 1935/2004 and applies across the supply chain, not only to finished packaging. In practice it flows like this:

In the United States, the FDA does not mandate a document by the name "DoC." Suppliers commonly issue an equivalent letter of guarantee citing the specific CFR sections and conditions of use the product meets. Functionally it plays the same role; the vocabulary differs.

Two things follow from the chain structure that buyers should internalise:

• Each link relies on the documentation from the link before it. We cannot declare something about an adhesive the formulator has not told us, and the converter cannot declare something about an ink we have never seen.
• The final DoC is the converter's, not the material supplier's. We can tell you what the laminate is. We cannot tell you what your printed label is, because the ink and the print conditions are yours.

Re-testing: when does it become necessary?

Neither EU nor US law sets a fixed re-testing interval for an unchanged formulation in an unchanged structure. But migration data has to be revisited whenever any of the following changes, because each can shift the result:

• A raw material, or a raw material supplier reformulating without notice
• The film or liner supplier, or the facestock grade
• The ink system
• The food type it contacts
• The storage or process conditions

The last point in that list is the one that catches buyers out. Many converters and brand owners also refresh test reports on a multi-year cycle as part of their own supplier-qualification programmes, even without a formulation change, simply to keep documentation current for audits. The more material risk sits in silent supply-chain substitutions — which is precisely why maintaining an active DoC chain with your material supplier matters as much as the original test report. A test report is a snapshot of one production run. The DoC chain is the ongoing claim.

Four questions to ask any label material supplier

1. Which regulation, by number, does your compliance claim reference? Accept "EU 10/2011," "21 CFR 175.105," "BfR XIV," "GB 9685-2016 Table A.5." Do not accept "food grade."
2. Was the migration testing done on the adhesive alone or on the finished laminate? The correct answer is the finished laminate. If the supplier cannot answer this, they do not understand their own documentation.
3. What are the stated conditions of use, and do they match my application? A DoC scoped to dry, non-fatty food at room temperature does not cover a fatty sauce in a retort pouch. Read the scope, not the conclusion.
4. Who issues the DoC for the printed label — you or my converter? If the supplier says they will cover the printed label, they are overpromising, because the ink is not theirs.

What we can and cannot declare

In the interest of not adding to the confusion:

We can provide a technical data sheet per construction stating facestock, adhesive chemistry, liner and caliper; a Declaration of Compliance for the unprinted laminate, scoped to the food types and conditions of use the construction is documented for; and the specific regulation and annex/table our claim rests on.

We cannot declare compliance for your printed label, because the ink, the coverage and the print conditions are outside our process. We cannot declare fitness for a food type or process condition we have not tested for. And we will not describe any product as "food safe" without naming the regulation behind the statement, because that phrase has no defined regulatory meaning.

How this guide was compiled

The regulation references, the Article 16 supply-chain obligation, the 0.01 mg/kg functional-barrier threshold, the CFR section split between general adhesives (175.105) and pressure-sensitive adhesives (175.125), and the alignment of GSO 1863/2013 with EU 10/2011 are drawn from the published regulations and from the regulatory documentation of adhesive and additive manufacturers operating in these markets — not from our own legal review. Regulatory scope and annex entries are amended over time. This is a practical map of the architecture and a list of questions, not legal advice, and it is not a substitute for your own compliance assessment or for a DoC scoped to your specific application.

If you are specifying for a food or pharmaceutical application, tell us the food type, the contact conditions and the destination market. We will tell you which regulation the construction can be documented against, what the scope of that documentation is, and — if the honest answer is that your application needs a migration study we do not have on file — we will say that before you order rather than after.

Does a Declaration of Compliance cover my printed label?

No. The Declaration covers what the issuing party supplies. A material supplier can declare the unprinted laminate; the converter or printer issues the final declaration for the printed label, because the ink and print conditions are theirs. If a material supplier offers to cover your printed label, they are overpromising.

Is migration testing done on the adhesive or on the finished label?

On the finished laminate or assembled packaging structure — not the adhesive in isolation. Migration limits under both the EU and US frameworks are assessed at the food-contact surface of the completed article. An adhesive can be fully compliant on its own positive list and still contribute to a laminate that exceeds the overall migration limit once combined with the facestock, coatings and ink.

What is the difference between 21 CFR 175.105 and 21 CFR 175.125?

175.105 covers adhesive components used in food packaging where the adhesive is not intended to contact food directly, typically because a functional barrier separates it. 175.125 is a separate, narrower listing specifically for pressure-sensitive adhesive formulations. They have their own positive lists and conditions of use, and clearance under one does not extend to the other.

Does complying with EU 10/2011 help with Gulf market compliance?

To a useful degree. GSO 1863/2013 on plastic food-contact materials was deliberately designed to mirror EU Regulation 10/2011, including permitted substances and migration limits, and GSO 2231/2012 reflects the general principles of the EU framework regulation 1935/2004. A construction properly documented against EU 10/2011 for the relevant conditions is in a strong starting position — which can save you paying for a duplicate test programme.

How often does migration testing need to be repeated?

Neither EU nor US law sets a fixed interval for an unchanged formulation in an unchanged structure. Data needs revisiting whenever a raw material or supplier changes, the film or liner supplier changes, the facestock grade changes, the ink system changes, the food type changes, or the storage and process conditions change. Many buyers also refresh reports on a multi-year cycle for audit purposes.

What should I do if a supplier says a product is "food safe"?

Ask which regulation, by number, the claim refers to. Accept answers such as EU 10/2011, 21 CFR 175.105, BfR XIV, or GB 9685-2016 Table A.5. "Food safe" and "food grade" have no defined regulatory meaning, and a supplier who will not name a regulation is making a marketing claim rather than a compliance claim.
