PFAS (per- and polyfluoroalkyl substances) in food-contact packaging has moved from an emerging concern to a regulatory reality. For egg brands, PFAS compliance affects packaging material choices, supplier relationships, testing protocols, and market access. The regulatory landscape is evolving quickly, and brands that wait for enforcement to catch up will find themselves scrambling.
This guide covers what PFAS are, why they matter for egg packaging specifically, the current regulatory landscape, testing and verification methods, and practical steps for achieving and documenting compliance.
What PFAS are and why they matter
PFAS are a class of more than 12,000 synthetic chemicals characterized by strong carbon-fluorine bonds. They were historically valued in food packaging for their ability to resist grease, moisture, and staining. Common applications included coatings on paper and paperboard food containers, wraps, and bags.
The problem: PFAS do not break down in the environment. They persist in soil, water, and biological systems indefinitely, earning the label "forever chemicals." Research has linked PFAS exposure to a range of health effects including immune system disruption, thyroid disease, certain cancers, and developmental issues.
Why egg packaging is in scope
Egg cartons are classified as food-contact packaging. Even though eggs have shells, the carton is in direct contact with the food product and is regulated as food-contact material. Any PFAS-containing coatings or additives in the carton material can potentially transfer to the egg surface.
This is why regulators have included egg cartons in the same category as other food packaging when enacting PFAS restrictions.
Current regulatory landscape
PFAS regulation in food packaging is happening primarily at the state level in the US, with federal and international action building momentum.
US state-level bans and restrictions
As of early 2026, the following states have enacted legislation restricting or banning PFAS in food-contact packaging:
| State | Effective date | Scope |
|---|---|---|
| Maine | January 2023 | Bans intentionally added PFAS in food packaging |
| Washington | January 2023 | Bans intentionally added PFAS in food packaging |
| California | January 2023 | Bans intentionally added PFAS in food packaging |
| Minnesota | January 2024 | Bans intentionally added PFAS in food packaging |
| New York | December 2023 | Bans intentionally added PFAS in food packaging |
| Vermont | July 2023 | Bans intentionally added PFAS in food packaging |
| Connecticut | December 2023 | Bans intentionally added PFAS in food packaging |
| Rhode Island | January 2024 | Bans intentionally added PFAS in food packaging |
| Maryland | January 2024 | Bans intentionally added PFAS in food packaging |
| Colorado | January 2024 | Bans intentionally added PFAS in food packaging |
| Hawaii | January 2024 | Bans intentionally added PFAS in food packaging |
| Oregon | January 2025 | Bans intentionally added PFAS in food packaging |
Additional states have bills pending or enacted with future effective dates. The trend is clearly toward broader coverage.
Key regulatory nuances
Intentionally added vs. total fluorine. Most state laws target "intentionally added" PFAS. However, some states also set total organic fluorine thresholds (commonly 100 ppm) that apply regardless of intent. This matters because PFAS can appear in packaging through contaminated recycled feedstock.
Definition scope. Regulatory definitions of "food packaging" generally include any packaging intended for direct food contact. Egg cartons clearly fall within scope.
Federal developments
At the federal level:
- The FDA has worked with manufacturers to phase out certain PFAS from food-contact applications and continues to evaluate the broader category
- The EPA has proposed designation of certain PFAS as hazardous substances under CERCLA, which could indirectly affect food packaging supply chains
- Congressional bills proposing federal PFAS-in-food-packaging bans have been introduced, though comprehensive federal legislation has not yet passed
International regulations
- EU: the European Chemicals Agency (ECHA) has proposed a broad restriction on PFAS that would affect food-contact materials once finalized
- Canada: Health Canada is evaluating PFAS in food packaging and has signaled potential future restrictions
- Denmark: banned PFAS in food-contact paper and paperboard since 2020
Testing and verification
PFAS-free claims must be substantiated through testing. Self-declarations are insufficient for regulatory compliance and increasingly insufficient for retailer acceptance.
Testing methods
Two primary analytical methods are used:
Total fluorine screening (CIC or PIGE analysis) measures total organic fluorine content. Results below 100 ppm are generally considered compliant. Cost is typically $200-500 per sample. This is the practical starting point for most egg brands.
Targeted PFAS analysis (LC-MS/MS) identifies and quantifies specific PFAS compounds. Cost is $500-1,500 per sample. Use this if total fluorine screening exceeds the threshold, to determine whether fluorine comes from intentionally added PFAS or background contamination.
Testing protocols
A robust PFAS testing program includes:
- Baseline testing: test your current packaging material to establish a compliance baseline
- Supplier testing: require your carton supplier to provide third-party test results for the materials used in your cartons
- Periodic verification: retest at defined intervals (annually at minimum) and whenever material suppliers or formulations change
- Batch-level testing: for highest assurance, test production batches rather than relying solely on material-level testing
Documentation standards
Maintain a compliance file that includes:
- Third-party lab test reports (not just certificates of compliance)
- Supplier declarations identifying materials used and confirming no intentionally added PFAS
- Chain of documentation linking test results to your specific carton orders
- Records of testing frequency and any corrective actions taken
Material choices for PFAS compliance
Not all packaging materials carry the same PFAS risk.
Corrugated cardboard
Corrugated-cardboard egg cartons are inherently advantaged for PFAS compliance. The material does not require moisture or grease barriers (eggs are dry products in shells), so there is no functional reason to add PFAS-containing coatings.
However, PFAS can enter corrugated cardboard through:
- Recycled content contamination: recycled paperboard may contain trace PFAS from other products in the waste stream
- Processing chemicals: some manufacturing chemicals could introduce trace fluorine
Responsible carton manufacturers address this by testing incoming materials, controlling their recycled fiber sources, and maintaining ongoing testing programs on finished products.
Foam (EPS)
Expanded polystyrene egg cartons do not typically contain PFAS. However, foam faces its own regulatory challenges (material bans, recyclability issues) that make it a poor long-term choice regardless.
Plastic (PET)
PET egg cartons are generally PFAS-free as a material but face increasing sustainability scrutiny that limits viability for brands prioritizing regulatory alignment.
Supplier verification
Your carton supplier is your primary compliance partner for PFAS-free packaging. Verifying their practices is essential.
Questions to ask your supplier
- Do you intentionally add PFAS to any component of your egg cartons? (The answer should be no.)
- Do you test finished products for total fluorine? (The answer should be yes, with results available.)
- What is your recycled content sourcing protocol? (They should describe how they screen recycled fiber for contamination.)
- Can you provide third-party test reports for the specific material used in my cartons? (They should be able to provide batch-level or material-lot-level documentation.)
- How often do you test? (Periodic testing on an established schedule, not just once.)
- What happens if a test fails? (They should have a documented corrective action protocol.)
Red flags
- Supplier provides only a self-declaration without third-party test data
- Testing was performed only once, years ago
- Supplier cannot identify the specific recycled fiber sources used
- Supplier is unaware of applicable PFAS regulations

Building a compliance strategy
A practical roadmap for PFAS-free egg packaging compliance:
Immediate actions
- Audit current packaging: obtain test results for your existing cartons to know your baseline
- Map your distribution: identify which states you sell in and their specific PFAS requirements
- Review supplier documentation: request current PFAS test data from your carton supplier
- Address gaps: if your current packaging does not meet the most restrictive requirements in your distribution footprint, start the transition process
Ongoing compliance
- Establish a testing cadence: annual minimum, with additional testing when suppliers or materials change
- Monitor regulations: subscribe to updates from state environmental agencies and industry associations tracking PFAS legislation
- Design for the strictest standard: rather than managing different packaging for different states, comply with the most restrictive applicable regulation across your entire distribution
- Document everything: maintain organized compliance files that can be shared with regulators, retailers, or auditors on request
Future-proofing
The regulatory direction is clear: PFAS restrictions in food packaging will expand, not contract. Brands that establish compliant packaging now avoid:
- Last-minute supplier switches when new regulations take effect
- Supply disruptions during transition periods
- Reputational risk from non-compliance or consumer advocacy attention
Corrugated-cardboard egg cartons from responsible manufacturers are the most straightforward path to PFAS-free compliance because the material does not require PFAS for performance and established suppliers maintain rigorous testing programs.
