Food-contact packaging evidence must match the material, intended food, contact time and temperature, and destination market. A generic “food-grade certificate” is not enough. Buyers should request a project-specific document set that identifies the supplied structure, its components or material family, applicable regulatory basis, conditions of use, relevant test reports and traceability.
The exact legal requirements differ by jurisdiction. In the United States, food-contact status can depend on applicable 21 CFR provisions, effective Food Contact Notifications or other authorization routes and their limitations, as outlined by the US FDA. In the European Union, the framework includes Regulation (EC) No 1935/2004, GMP Regulation (EC) No 2023/2006 and material-specific measures. Buyers should use qualified regulatory support for their product and market.
This article is procurement guidance, not legal advice.
Start With Intended Use
A supplier cannot assess relevance without knowing:
- Food type, including fat, acid, alcohol or aqueous character where relevant
- Direct or indirect contact
- Contact time and temperature
- Hot fill, frozen storage, microwave, boil or retort exposure if applicable
- Single use or repeated use
- Target country or region
- Package layer that contacts the food
- Printing, adhesive, coating, recycled content and colorants
The same film may be acceptable for one use and outside the conditions of another authorization. “Compliant” should always be followed by “for which use and market?”
1. Material and Finished-Structure Specification
The foundation is a controlled specification identifying the supplied pouch or rollstock. It should connect product code, layer structure, nominal thickness, contact layer, adhesive or coating system where relevant, components such as zipper or spout and artwork or ink system.
Ask how substitutions are controlled. A change in resin grade, adhesive, ink, color concentrate or recycled content can affect the compliance assessment even if the finished pouch looks the same.
2. Declaration or Statement of Compliance
Terminology and legal requirements vary. A declaration should identify the issuer, product or material covered, regulatory references, issue date, relevant restrictions and conditions of use. It should be signed or otherwise controlled by an authorized organization.
Do not accept a declaration for a broad material family without confirming that your supplied construction falls within its scope. Check whether it covers the complete laminate or only one component.
3. Supporting Supplier Declarations
The converter relies on information from film, resin, adhesive, ink, coating, zipper and fitment suppliers. These upstream declarations may contain confidential formulation details, but the converter should be able to evaluate relevant restrictions and pass necessary information down the supply chain.
Ask who maintains the compliance assessment and how updates are handled. A test report alone cannot replace knowledge of all intentionally used components and their authorization conditions.
4. Migration or Extraction Test Reports
Migration testing can provide evidence under defined simulant, time and temperature conditions. Review:
- Laboratory identity and report number
- Sample description and material construction
- Test standard or regulatory method
- Food simulants
- Contact time and temperature
- Surface-area-to-volume assumptions
- Overall and specific migration results where applicable
- Detection limits and units
- Date and any conclusion limitations
A passing report for one condition does not automatically cover hotter, longer or more demanding contact. Confirm whether the worst-case intended use is represented and whether the tested material matches the order.
5. GMP and Quality-System Evidence
EU Regulation (EC) No 2023/2006 requires good manufacturing practice across relevant stages for food-contact materials. A supplier may support its controls with procedures, audits or management-system certifications. These documents show how production is managed; they do not alone establish the compliance of a specific pouch.
During a supplier review, ask about raw-material approval, change control, batch identification, ink and adhesive handling, curing, contamination prevention, retained records and nonconformance management.
6. Certificate of Analysis or Conformance
A lot-specific certificate can confirm agreed characteristics or conformance for a shipment. The useful content depends on the product and contract. It may identify batch, quantity, dimensions, material code and selected test results.
Do not confuse a certificate of analysis with a regulatory declaration. One reports batch information; the other explains regulatory status or basis. Define which documents are required before placing the order.
7. Traceability Records
Traceability links finished goods to production and material lots. Ask how pouches, bundles, cartons and documents carry order or batch identification. Determine how long records and retained samples are kept, and how the supplier would support a complaint or recall investigation.
For printed packaging, artwork revision is part of traceability. Incorrect allergen or ingredient information is not corrected by a compliant film.
8. Printing-Ink and Set-Off Controls
Printing is often on the non-food-contact side or reverse-printed inside a laminate, but migration, set-off and transfer still require control. GMP Regulation (EC) No 2023/2006 includes requirements relevant to printing inks on non-food-contact surfaces, including preventing transfer through the substrate or by set-off at levels that could endanger health or unacceptably change food.
Ask about ink system, curing or drying, reel storage, lamination and printed-surface contact during production. A “non-food-contact ink” statement is not a substitute for controlling the final construction and foreseeable conditions.
9. Evidence for Zippers, Valves and Spouts
Accessories can contact food or package headspace and must be included in the assessment where relevant. Confirm component material, supplier, conditions of use and change control. For spouts and caps, product formulation and fill temperature can be important. For valves, attachment and film compatibility affect integrity even when the component material is acceptable.
10. Claims That Need Separate Evidence
Terms such as recyclable, compostable, biodegradable, PFAS-free, BPA-free, heavy-metal-free or suitable for a particular treatment have different technical and legal meanings. Do not infer them from “food grade.” Request the definition, test basis, scope and market where the claim will be used.
Environmental claims should describe the complete package and actual collection or processing context. Product-protection claims require separate performance evidence.
A Practical Document-Review Table
| Document | Main question | Common limitation |
|---|---|---|
| Product specification | What exactly are we buying? | May omit regulatory basis |
| Compliance declaration | On what basis and conditions is it suitable? | Scope may be broader or narrower than the order |
| Migration report | What was tested under which conditions? | Test conditions may not match intended use |
| Upstream declarations | Are component restrictions understood? | Some formulation data may be confidential |
| GMP/quality certificate | How is manufacturing controlled? | Does not prove product-specific compliance |
| COA/COC | Does this batch meet agreed items? | Not a substitute for compliance assessment |
| Traceability record | Can lots and revisions be connected? | Retention period and depth vary |
Red Flags During Document Review
- No product code or structure linking documents to the supplied pouch
- Expired, unreadable or altered reports
- Reports for a different material, thickness or supplier
- Missing time, temperature, simulant or conditions of use
- “FDA approved” used as a blanket claim without regulatory basis
- Certificate logos with no scope or issuing body
- A declaration that ignores inks, adhesives or accessories
- Supplier unable to explain substitutions or change notification
- Environmental claims presented as food-contact evidence
Responsibilities Across the Supply Chain
The material supplier provides information for its product. The converter selects and processes components into packaging. The filler controls food, filling and final seal. The brand owner places the packed product on the market and controls labeling and claims. Laboratories and regulatory advisers provide defined services.
Document these roles in the project. A packaging supplier can support evidence, but the buyer must confirm that the final package and food application meet destination-market obligations.
What to Send the Supplier
Provide destination market, product description, contact conditions, fill temperature, target shelf life, pouch format, all required accessories and any customer-specific restricted-substance or retailer protocol. Ask the supplier to state open assumptions and which evidence is available before final material approval.
Review FULL PACKING’s quality approach and contact the team for a project-specific document discussion. Unverified certifications or market claims should not be added to a specification.
US Review: Authorization and Conditions of Use
In the United States, FDA explains that food-contact components may be covered through regulations in 21 CFR Parts 174–179, effective Food Contact Notifications, prior sanctions, Threshold of Regulation exemptions or other applicable bases. An authorization is not a general approval of every finished package. It identifies a substance or use and includes specifications and limitations.
Ask the supplier to connect each relevant component with its basis and intended conditions. For an effective Food Contact Notification, FDA notes that the notification is proprietary to the manufacturer for which it is effective; sourcing the same chemical name from another manufacturer may not provide the same basis. Buyers should have regulatory specialists review composite formulations and final use.
A letter of guaranty may support business-to-business communication where appropriate, but it should identify the product and basis. It does not replace the brand owner’s review of the filled package and labeling.
EU Review: Framework, GMP and Material-Specific Measures
Regulation (EC) No 1935/2004 establishes general requirements for materials intended to contact food. Regulation (EC) No 2023/2006 establishes GMP rules, including quality assurance, quality control and documentation. Plastics and other material groups may have additional specific measures and amendments.
For a plastic laminate, the declaration and supporting information should reflect applicable rules, restrictions, migration conditions and intended use. Printing inks, adhesives and non-plastic components may require separate assessment. Do not treat one plastics declaration as proof that every part of a printed, laminated, zippered pouch has been reviewed.
Build a Document Matrix Before Approval
Create one row for each material and accessory: outer film, barrier layer, sealant, adhesive, ink/coating, zipper, valve, spout, cap and label. Record supplier, product code, declaration date, applicable market, limitations, supporting test and change status.
Then connect the matrix to the finished-pouch specification. This reveals gaps early—for example, a fitment declaration covering ambient contact when the product is hot-filled, or a migration report for a clear film when the order uses a colored grade.
Change Control After the First Order
Compliance is not a one-time folder. Agree which changes require notification: resin source, adhesive, ink, coating, color concentrate, layer thickness, recycled content, zipper or fitment. The supplier should evaluate the effect before implementation and update documents where needed.
On reorder, verify that the specification revision and document matrix are current. Regulatory amendments can also change the review even when the physical package has not changed. Assign an internal owner and review interval.
Audit Questions for Quality and Regulatory Teams
- Who approves new food-contact raw materials?
- How are supplier declarations checked and renewed?
- How are restrictions and conditions communicated to production and customers?
- How are inks, adhesives and set-off controlled?
- What links finished lots to raw-material lots?
- How are substitutions prevented or approved?
- Which records and retained samples are kept, and for how long?
- How are regulatory updates monitored?
- How are customer-specific requirements reviewed?
- What happens when a document expires or a supplier changes formulation?
Frequently Asked Questions
Is “FDA approved” the correct description for a food pouch?
Often it is too broad. In the US, component status depends on applicable authorizations and conditions of use. Ask for the specific regulatory basis and limitations rather than relying on a logo or generic phrase.
Do I need a migration test for every order?
Requirements depend on market, material, use and change control. Existing representative evidence may be relevant in some cases; other projects need new testing. Obtain qualified advice.
Does ISO certification prove food-contact compliance?
No. A management-system certificate can support confidence in processes but does not establish the regulatory status of a specific material or intended use.
Who should keep compliance documents?
Each responsible business should retain the records required for its role and jurisdiction. Agree document delivery, revision and retention before production.
Can one report cover different pouch colors and structures?
Only when the report and compliance assessment legitimately cover those variants. Different inks, adhesives, layers or use conditions may require separate review.
Conclusion
Trustworthy food-contact review connects intended use to a controlled structure, regulatory basis, relevant testing and traceability. Ask for scope and conditions, not just certificates. Keep compliance, quality-system, performance and environmental claims as related but distinct evidence streams.
