In-N-Out Burger · Fast-Casual Food Packaging
Custom Fast Burger Paper Packaging
In-N-Out has not disclosed PFAS status of burger packaging.
In-N-Out Burger's paper packaging contains a water and grease-resistant coating typical of fast food wrappers, likely fluorinated but unconfirmed. Brand silence on PFAS composition limits assessment accuracy.

The full breakdown
What it's made of and why it matters
In-N-Out burger wrappers are bleached paper with a grease-resistant coating of unspecified composition. The bleaching process itself is not a safety concern, but the grease-resistant coating is the critical unknown: such coatings historically rely on fluorinated compounds (PFAS) or, less commonly, silicone or wax-based alternatives. Without disclosure from In-N-Out, the exact chemistry cannot be verified. Grease resistance is functionally important to prevent oil seepage, but the coating's safety profile depends entirely on what chemical is actually used.
The brand's record and disclosure
In-N-Out Burger has not publicly disclosed the specific composition of their food packaging coatings or their PFAS stance. The company does not maintain a published chemicals policy for packaging materials. This silence is notable given growing industry and regulatory scrutiny of PFAS in food-contact materials, particularly after the FDA's 2022 voluntary phase-out recommendations for PFAS in food packaging. Without third-party certification (e.g., through SFI or specific PFAS-free commitments), there is no independent verification of the wrapper's chemical safety profile.
How it compares in its category
Most major fast-food chains still use fluorinated grease-resistant coatings on burger wrappers because alternatives (uncoated kraft, wax, or silicone) have trade-offs in performance or cost. Some competitors (e.g., Chipotle, select McDonald's markets) have moved toward PFAS-free alternatives, though these are not universal. In-N-Out's packaging transparency lags peers; chains that have committed to PFAS elimination typically advertise this. Single-use food wrappers represent high-frequency, low-dose contact, making the coating choice more significant than occasional use items.
If you buy it
Routine consumption of food in these wrappers carries minimal acute risk; short contact time and the barrier function of paper itself limit leaching. However, avoid prolonged contact of hot or greasy food with the wrapper if possible (transfer to a plate when home). Do not microwave food in the wrapper or deliberately heat it. Because the coating chemistry is unverified, consumers concerned about PFAS exposure should advocate for In-N-Out disclosure or consider requesting uncoated alternatives if the chain offers them.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
PFAS in grease-resistant coating
Grease-resistant food-contact coatings historically rely on fluorinated compounds. In-N-Out has not disclosed coating chemistry; risk cannot be ruled out but also cannot be confirmed from available public information.
Bleached paper fiber migration
Bleaching of food-contact paper using chlorine-based or oxygen-based processes is regulated and compliant with FDA standards. No documented safety concern for In-N-Out wrappers specifically or bleached food paper in general under normal use.
Coating degradation and leaching under heat or grease
Grease-resistant coatings on food wrappers can degrade or transfer when exposed to high heat, prolonged contact with fatty foods, or when deliberately heated (e.g., microwave). In-N-Out does not specify coating heat stability limits, so worst-case scenarios (hot burger held in wrapper) cannot be fully assessed.
Ink or printing chemical transfer
In-N-Out wrappers use food-contact-approved inks for branding. No known recalls or reports of ink migration from In-N-Out packaging. FDA-compliant food-packaging inks are not expected to leach under normal storage and use.
Unknown proprietary coating composition
The single largest hazard is lack of transparency. The coating is proprietary and unspecified, preventing independent assessment of chemical safety. This uncertainty, combined with PFAS prevalence in this product category, justifies the 'care' tier rather than unconditional 'buy'.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
