Custom Fast Food Wrappers and Sandwich Bags

F · High PFAS

Grease-resistant food wrappers often contain PFAS; In-N-Out discloses nothing.

Verdict: SkipPFAS in grease-resistant coating is the primary concern; no other hazards documented, but brand transparency is absent.

In-N-Out's wrappers and bags use grease-resistant coatings typical of fast-food packaging, which commonly contain PFAS. The brand has made no public disclosure about PFAS content or safer alternatives.

The full breakdown

What it's made of and why it matters

In-N-Out's wrappers and sandwich bags are coated paperboard designed to repel grease and moisture without becoming soggy or leaking. The coating is the functional part and the likely source of PFAS chemicals, which are used in food-contact paper and board manufacturing specifically to create water and oil repellency. No public information confirms whether In-N-Out uses legacy PFOA/PFOS or newer, shorter-chain PFAS alternatives, or non-fluorinated barriers.

The brand's record and disclosure

In-N-Out does not publicly disclose wrapper materials, PFAS testing, or sourcing of grease-resistant coatings. The company has not signed pledges to eliminate PFAS from food packaging, in contrast to some competitors who have committed to phase-out timelines or alternatives research. No recalls or safety investigations specific to In-N-Out wrappers are on record.

How it compares in its category

Most conventional fast food wrappers use similar fluorinated coatings; In-N-Out's silence matches the industry norm of minimal disclosure. Some chains (Chipotle, others) have begun transitioning to PFAS-free barriers or compostable alternatives, though rollout remains incomplete. Unbleached kraft or paper with non-fluorinated soy-based coatings exist but are less common at mainstream fast food scale.

If you buy it

No special handling is required during normal use. Do not reuse wrappers for food storage or heating; the coating degrades under microwave exposure and intended single-use design means durability is not tested for reuse. If concerned about PFAS intake, limit frequency of consumption or request unwrapped options when available. Composting or recycling is acceptable; home disposal does not pose additional risk beyond the initial exposure from food contact.

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.”

None known

BPA/BPS and bisphenol alternatives

No evidence in public records that In-N-Out wrappers contain BPA or its replacements; coated paperboard typically relies on fluorinated polymers rather than bisphenol chemistry for grease resistance.

Possible

Microplastics from coating breakdown

Synthetic polymer coatings can degrade mechanically during handling, storage, and contact with hot greasy food; minute particles may migrate into food, though migration rates and particle size from this specific product are not documented.

None known

Bleach residues (chlorine byproducts)

In-N-Out's paper source and bleaching method are not disclosed publicly; standard paperboard manufacturing typically uses chlorine-free or elemental chlorine-free bleaching, which minimizes dioxin risk in food contact, but confirmation is unavailable.

None known

Ink migration from printing

No recalls or studies specific to In-N-Out wrapper inks are on record; food-contact printing inks are regulated under FDA guidelines, and outer-surface printing poses minimal direct food-contact risk on single-use wrappers.

Possible

Adhesives and barrier layer components (non-PFAS)

Polyethylene or other synthetic adhesives used to bond wrapper layers to paper can leach under heat or prolonged contact; composition is not publicly specified by In-N-Out, and migration potential under normal use (ambient or briefly warm food) is expected to be low.

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.
