📌 Key Takeaways
Food-grade certification means nothing without documented proof of compliance aligned to your destination market and specific use case.
- Define Before You Request: Specify food type, contact scenario, temperature, and duration in a fill-in-the-blank statement to force supplier clarity before evaluation begins.
- Demand Finished-Product Documentation: Request Declarations of Compliance covering the complete bag structure—base paper, inks, coatings, and adhesives—not just substrate certifications.
- Match Test Conditions to Reality: Verify that migration test reports reflect your actual temperature, contact time, and food type; ambient-only testing doesn’t validate hot-food applications.
- Screen With Red Flags: Reject suppliers offering generic “food-safe” claims with no regulatory reference, missing contact conditions, or absent change-control procedures.
- Build Traceability Into Approval: Establish batch identification and change-notification requirements before awarding contracts to prevent silent material drift over time.
Documentation scope and verification discipline prevent compliance failures that price negotiations cannot fix.
Procurement teams sourcing food delivery packaging will gain immediately usable checklists and copy-paste supplier questions here, preparing them for the regulatory framework and workflow details that follow.
A supplier says their paper bags are “food-grade.” The label looks official. But when your compliance team asks for documentation, the response is vague—or nonexistent.
This scenario plays out constantly in food delivery packaging procurement. Many of the verification challenges mirror broader supplier capability assessment issues covered in how to verify supplier capability (when the price list isn’t the risk). The term “food-grade” sounds definitive, but it’s not a universal certification. It’s a compliance claim that only means something when tied to a specific use case, a specific destination market, and verifiable documentation.
Food-grade delivery packaging requires verifiable food-contact compliance documentation aligned to the destination market. Without that alignment, a “food-grade” claim is just marketing language.
This article provides a practical compliance checklist, explains which documents to request from suppliers, and includes copy-paste questions you can use in your next email or RFQ. The goal: turn vague claims into a verification workflow your team can use immediately.
Fast Path: The Core Principle
A fast path that works in most sourcing workflows: Define the intended use case (food type, time, temperature, direct versus indirect contact). Ask for a Declaration of Compliance for the finished bag, not just the base paper. Check whether inks, coatings, and adhesives are included in the scope. Match any test evidence to real conditions. Verify traceability and change control to prevent silent material changes. Only then treat “food-grade” as a decision-ready claim.
General principles apply broadly, but details vary by market and use case. Verify applicability with qualified compliance professionals for your specific product and distribution scenario.
What “Food-Grade” Means for Delivery Packaging
“Food-grade” is not a single standard. It’s a shorthand for compliance with food-contact regulations—and those regulations differ based on how the packaging will actually be used.
The distinction that matters most is direct versus indirect food contact. Direct contact means the food touches the packaging surface. Indirect contact means the food is wrapped or contained inside something else, but the outer packaging could still affect safety or impart odor. The same paper bag might be compliant for carrying a wrapped sandwich but not compliant for holding unwrapped pastries.
Compliance also depends on the food type (dry, wet, fatty, acidic), contact duration, and temperature exposure. The migration of substances follows the laws of diffusion, where increased temperature and fat content significantly accelerate the transfer of chemicals from packaging to food. For hot, fried applications, documentation must prove the material was tested using Fatty Food Simulants (such as Simulant D2 or 95% Ethanol) at temperatures that match or exceed peak service heat, as ambient-temperature testing is scientifically insufficient for these high-risk scenarios..
This is why a generic “food-safe” claim is not equivalent to a supplier declaration of compliance supported by test reports. The claim only becomes meaningful when it specifies what use case, under what conditions, and according to which regulatory framework.
A simple internal template to keep suppliers honest about scope:
Fill in this statement and include it in your RFQ or supplier communication:
“Our delivery packaging is for [food type: dry / fatty / acidic / aqueous], [direct / indirect] food contact, up to [max temperature] for [max time]. Printing is [none / external only / includes inner surfaces]. Please provide compliance documentation for the finished bag structure, including inks/coatings/adhesives where applicable.”
This single-sentence specification forces clarity on both sides and prevents scope drift during supplier evaluation.
The Food-Grade Compliance Checklist Buyers Can Use Immediately
Before contacting suppliers, define your use case. Then use this checklist to structure your documentation requests and verification process. This checklist is designed as a self-contained, copy-paste-friendly resource for procurement teams—a zero-click asset you can use immediately without external references.
| Your Use Case Input | Document to Request | What to Verify | Red Flags |
| Food type (dry, wet, fatty, acidic) | Declaration of Compliance (DoC) | DoC specifies food types covered | Generic “all food types” with no conditions stated |
| Direct or indirect contact | DoC + material specification | Scope explicitly states contact type | No mention of contact scenario |
| Temperature range (ambient, hot, cold) | Migration test reports | Tests conducted at relevant temperature | Tests only at room temperature for hot-food application |
| Contact duration (seconds, minutes, hours) | Migration test reports | Test duration matches or exceeds your use | No duration specified in test conditions |
| Printed or unprinted packaging | Ink/coating compliance documentation | Inks and coatings included in compliance scope | Paper compliance only; printing excluded |
| Destination market (US, EU, other) | DoC referencing applicable regulation | Correct regulatory framework cited | EU regulation cited for US-only distribution; no regulation named |
| Batch consistency requirements | Quality management documentation | Change-control and traceability procedures | No batch identification or change-notification process |
| Volume and ongoing supply | Supplier audit or certification records | GMP compliance; ISO or equivalent | No third-party verification available |
Adapt the left column to your specific product, then use the remaining columns to evaluate supplier responses. The red flags column helps you screen out incomplete or evasive supplier claims before investing time in detailed evaluation.

Which Standards Matter Depends on Where the Packaging Will Be Used
Food-contact regulations are destination-market rules, not universal requirements. The regulatory framework that applies depends on where the packaged food will be sold or consumed.
For the United States, the FDA regulates food-contact substances under 21 CFR Part 176, which covers paper and paperboard components intended for food contact.[1] However, this regulation is split into two distinct categories based on whether the food is “wet/fatty” (CFR 176.170) or “dry” (CFR 176.180).
Procurement Decision Matrix:
- If you are sourcing for “Delivery Bags” (Outer Carrier): If the food inside is already sealed in a primary container (like a plastic clamshell or wrapped foil), 176.180 is often sufficient as it constitutes indirect contact with dry surfaces.
- If you are sourcing for “Pastry/Burger Bags” (Primary Contact): You must demand documentation citing 176.170. Using 176.180-certified paper for a greasy burger is a regulatory violation because the extraction limits for fatty foods have not been verified.
Once you have identified whether your use case requires 176.170 or 176.180 compliance, the next step is to verify the supplier’s documentation against these specific requirements.
For the European Union, the framework regulation (EC) No 1935/2004 establishes general safety requirements for all food-contact materials.[2] Paper and board specifically are often evaluated against national measures and industry guidance, including the German BfR Recommendation XXXVI, which provides detailed technical criteria for paper and board in food contact.[5]
The EU also requires Good Manufacturing Practice (GMP) under regulation (EC) No 2023/2006, which applies to the production process for food-contact materials.[3] The European Commission provides an overview that helps buyers understand which rules apply to specific material types.[4]
For other markets, check whether the destination country recognizes EU or US standards, has its own framework, or requires specific import documentation.
The practical step: before requesting supplier documents, confirm which regulatory framework applies to your distribution. Then verify that supplier documentation explicitly references that framework.
Supplier Documents to Request (and What Each One Proves)
Three categories of documentation establish whether a “food-grade” claim is verifiable.
Declaration of Compliance (DoC): This is a supplier statement describing which rules the packaging is designed to comply with, and the conditions under which that claim is valid. A useful DoC specifies the applicable regulation, the food types and contact conditions covered, and confirms that all components (including inks, coatings, and adhesives) are included in the compliance scope. The DoC should be specific to the finished bag—including converting and printing components when relevant—not just the base paper. A DoC that says only “food-safe” without specifying conditions or regulations provides little verification value.
Migration Test Reports: Migration refers to the movement of substances from packaging materials into food under specific conditions. Test reports should document the food simulants used, the time and temperature of exposure, and the substances measured. The test conditions must match or exceed your actual use case. A test conducted at 20°C for two hours doesn’t validate compliance for hot food held at 70°C for thirty minutes. Availability and detail level vary by supplier, but when reports exist, they’re helpful only when test conditions match reality.
Traceability and Change-Control Documentation: Batch consistency is where many food-grade claims fail operationally. Supplier verification should include traceability, batch consistency controls, and change-notification discipline. For international suppliers, how to vet wholesale paper bag suppliers: a remote audit checklist provides a practical framework for desk-based verification before committing to orders. Ask how the supplier identifies batches, whether they notify customers of material or process changes, and what quality controls apply to ongoing production. Many food-grade failures are operational—materials drift over time without the buyer’s knowledge.

Common Failure Modes in Food Delivery Packaging (and How to Prevent Them)
Food-contact risk depends on food type, contact time, contact temperature, and direct versus indirect contact. Understanding common failure modes helps translate compliance requirements into practical specification choices.
Grease and moisture penetration. Paper bags used for fried or moist foods must resist grease migration without using non-compliant barrier treatments. When sourcing base materials with specific grease-resistance properties, kraft paper suppliers and kraft paper manufacturers can provide material specifications and certificates of analysis to verify performance characteristics. Define whether food is hot and greasy and whether contact is direct. Then confirm the material spec and the documented scope include any barrier layer. Specify grease resistance requirements and verify that any coatings or treatments are included in the compliance documentation.
Odor and taint transfer. Even indirect contact can affect food quality if packaging materials impart off-odors. This risk increases with recycled fiber content due to the potential migration of Mineral Oil Hydrocarbons (MOSH and MOAH) from residual newsprint inks; consequently, procurement must verify that recycled materials utilize a functional barrier or have undergone specific migration testing to ensure these compounds do not transfer to food. Treat odor and taint as a requirement, especially when dwell time is long or food is aromatic. Inks, coatings, and adhesives are part of the risk surface. Request odor and taint testing if your product is sensitive.
Ink migration and set-off. Ink, adhesive, and coating choices can affect migration risk and odor/taint outcomes. Printed bags require documentation confirming that inks are formulated for food-contact applications and that migration testing covers the printed product, not just the base paper. Require that printing systems are included in compliance scope and that change control exists for ink substitutions.
Heat exposure beyond tested limits. Hot food applications require testing at relevant temperatures. Write the maximum temperature into the use-case statement and verify documentation reflects that condition. Confirm that migration tests reflect actual use conditions, not just ambient temperature.
Material specifications like GSM (grams per square meter) and burst factor affect durability but don’t directly address food-contact compliance. For guidance on how these specifications impact bag performance, see paper bag raw material grades: gsm and burst factor explained.
Copy-Paste Supplier Questions for Your Next Email or RFQ
Use these questions directly in supplier communications. Group them by topic area based on your priorities.
Compliance and Regulatory Scope:
- Which food-contact regulation does your Declaration of Compliance reference (e.g., FDA 21 CFR 176, EU 1935/2004, BfR XXXVI)?
- Does your DoC specify the food types, contact conditions, and temperature ranges covered?
- Are printed and converted components (inks, coatings, adhesives) included in the compliance scope?
- Is the DoC for the finished bag (paper + inks/coatings/adhesives) or only base paper?
- Is the product intended for direct food contact, and under what food types/time/temperature?
Materials and Testing:
- Can you provide migration test reports? What food simulants, temperatures, and contact times were used?
- If the bags are printed, do you have compliance documentation specific to the inks and coatings used?
- Have odor and taint tests been conducted? Can you share results?
- Do the test conditions cover hot food, steam, or greasy/fatty food scenarios (if applicable)?
- What ink system, coatings, and adhesives are used, and are they in the compliance scope?
- Where is printing located relative to any food-contact surface (external only versus other)?
Process Controls and Traceability:
- How do you identify and track production batches?
- What is your change-notification policy if materials or processes change?
- Do you hold GMP certification or equivalent quality management documentation?
- What lot/batch traceability is provided for this SKU?
- What process controls prevent batch-to-batch drift in materials and converting?
Verification:
- Can you provide a sample with batch identification for our internal testing?
- Are you able to supply updated documentation annually or upon request?
- Does your Declaration of Compliance specify whether the material is cleared under FDA 21 CFR 176.170 (Aqueous/Fatty) or only 176.180 (Dry)? Please provide the extraction test results if 176.170 is claimed.
Adapt these questions to your specific use case. The goal is to move from “Do you have food-grade bags?” to “Can you document compliance for our specific application?”
A Simple Internal Workflow: Procurement + Ops + Brand
For SME teams, a lightweight approval workflow prevents compliance gaps without creating bureaucratic overhead.
Step 1: Use-case definition (Procurement + Ops). Complete this statement: “We need packaging for [food type], [direct/indirect] contact, at [temperature range], for up to [duration], distributed in [market].” Ops defines the use case with input on food type, temperature, time, and direct versus indirect contact.
Step 2: Supplier documentation request (Procurement). Use the checklist and questions above to request specific documents from potential suppliers. Procurement requests and reviews DoC, scope documentation, and traceability/change-control evidence.
Step 3: Technical review (Ops). Verify that test conditions match or exceed the defined use case. Flag any gaps between documentation scope and actual application.
Step 4: Brand and print review (Brand/Marketing). If packaging is printed, confirm that brand requirements don’t introduce non-compliant inks or finishes. Brand and Marketing confirm print coverage constraints and risk tolerance for odor and appearance. Coordinate with Ops on any design changes.
Step 5: Approval and documentation filing (Procurement). Maintain a file linking supplier, batch, and compliance documentation. Establish a review trigger for supplier changes or annual renewal. A single owner signs off that documents match the use case and that change control is documented.
Step 6: Ongoing monitoring (All). Set calendar reminders to request updated documentation and confirm no material or process changes have occurred.
Next Steps: Move from “Claims” to Verifiable Sourcing
Procurement teams reduce compliance risk by specifying the intended use case and required documents upfront. A “food-grade” label means nothing without documentation that proves scope, conditions, and supplier controls.
Start with the use-case definition. Request specific documents. Verify that test conditions match your application. And establish a simple workflow to maintain compliance over time.

Frequently Asked Questions
Is “food-safe” the same as “food-grade” for paper bags?
These terms are often used interchangeably, but neither has a fixed regulatory definition. What matters is whether the supplier can document compliance with the specific food-contact regulations applicable to your use case and destination market. A “food-safe” or “food-grade” claim without supporting documentation—specifying the regulation, food types, contact conditions, and included components—provides no verification value.
Do paper delivery bags need certification if food is wrapped inside?
Indirect food contact still carries compliance considerations. Even when food doesn’t touch the outer packaging directly, migration of substances or transfer of odors can occur. The level of risk depends on the barrier properties of the inner wrap, the food type, and the duration and temperature of contact. Request documentation that addresses indirect contact scenarios if that matches your use case. Risk is often lower with indirect contact, but documentation still matters for odor, taint, and printing set-off.
What should a supplier Declaration of Compliance include?
A useful DoC specifies the applicable regulatory framework, the food types and contact conditions covered, and confirms that all components—including inks, coatings, and adhesives—fall within the compliance scope. It should also identify the legal entity making the declaration and provide a date or version reference. The DoC should reference applicable rules, state intended conditions (food type/time/temperature/contact type), and provide clear scope for the finished structure.
Do printed paper bags create additional compliance risk?
Yes. Inks, coatings, and adhesives can introduce substances that migrate into food or affect odor and taint. A supplier’s base paper may be compliant while the finished printed product is not. Always request documentation confirming that the printed product—not just the substrate—has been evaluated for food-contact compliance. Inks, coatings, and adhesives may change migration and odor outcomes, so scope must include converting components.
How do I specify the intended use case so a test report is meaningful?
Define the food type (dry, wet, fatty, acidic), whether contact is direct or indirect, the expected temperature range, and the maximum contact duration. Provide this information to suppliers when requesting test reports, and verify that the test conditions in the report match or exceed your actual application. State food type, direct/indirect contact, maximum temperature, and maximum time—then match evidence to those conditions.
What are the biggest red flags when a supplier claims “food-grade”?
Watch for generic claims with no reference to a specific regulation, DoCs that don’t specify food types or contact conditions, test reports conducted under conditions that don’t match your use case, missing documentation for printed or converted components, and absence of batch traceability or change-control procedures. No destination-market reference, no stated conditions, no converting/printing scope, and no change-control discipline are all critical warning signs.
How do sustainability certifications like FSC relate to food-grade compliance?
Sustainability certifications like FSC (Forest Stewardship Council) verify responsible sourcing but are separate from food-contact compliance. A bag can be FSC-certified yet not compliant for food contact, or vice versa. Many buyers need both. For guidance on verifying sustainability claims alongside food-contact documentation, see avoiding greenwashing: how to verify supplier sustainability claims. Both verification processes can run in parallel using similar documentation-request frameworks.
Key Terms
Declaration of Compliance (DoC): A supplier statement describing which rules the packaging is designed to comply with and the conditions under which that claim is valid. A complete DoC specifies the applicable regulation, intended food types, contact conditions (direct/indirect, time, temperature), and confirms that all components including inks, coatings, and adhesives are within scope.
Migration: The movement of substances from packaging materials into food under specific conditions (time, temperature, food type). Migration testing evaluates whether substances transfer at levels that could affect safety or quality, using food simulants that represent actual use conditions.
Indirect Food Contact: A scenario where food does not touch packaging directly (for example, food wrapped in an inner liner). Even with indirect contact, packaging can still affect safety and impart odor or taint, so compliance documentation remains important though risk levels may differ from direct contact.
