SkinnyPop Butter Microwave Popcorn
Microwave popcorn bags commonly use PFAS-based coatings; skip if concerned.
SkinnyPop does not disclose PFAS status for this product. Microwave popcorn bag liners typically contain grease-resistant coatings that may include PFAS; no third-party testing publicly available for this specific product.

What SkinnyPop Butter Microwave Popcorn is made of, ingredients and materials
SkinnyPop Butter Microwave Popcorn bags use a multi-layer structure, paper exterior, polymer film middle layers, and an inner grease-resistant coating. That coating is almost certainly PFAS-based (fluorinated compounds) because microwave popcorn bags routinely require grease barriers to prevent oil saturation during high-heat cooking. The inner coating contacts both the popcorn and heating vapors, creating a potential migration pathway into your food.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.

No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Even if PFAS-free alternatives were used, any synthetic barrier coating can degrade under microwave heat and release small amounts of polymer into food. No recalls or studies specific to SkinnyPop have been published, but this is a material class risk.
Source, ATSDR ↗Microplastics
Repeated heating cycles or damaged bags may shed microscopic polymer fragments into popcorn. Not documented for this brand specifically, but a known concern in microwave food packaging literature.
Source, EPA ↗Volatile organic compounds (VOCs) from bag off-gassing
Multi-layer polymer bags can release trace VOCs during microwave heating. Ventilate your microwave area and do not let cooked popcorn sit in the hot bag for extended periods.
What’s reassuring
BPA & bisphenols
SkinnyPop bags use printed ink for branding. No evidence of BPA contamination has surfaced, but legacy microwave popcorn bags sometimes used BPA-containing inks; Frito-Lay has not publicly confirmed BPA-free status for this product.
Source, FDA ↗Thermal decomposition of butter flavoring compounds
The 'butter' flavoring in this product is likely diacetyl or diacetyl-free substitute (post-2009 reformulation). No specific hazard data exists for SkinnyPop's formulation, but this is a food additive choice, not a packaging hazard.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand is a Frito-Lay subsidiary and has not published specific statements about PFAS use in microwave popcorn packaging. Frito-Lay has signed the Responsible Microbead Pledge but has not committed to PFAS phase-out in food-contact materials. The company does not disclose bag material composition on product labels or their website, making independent verification difficult.
How it compares in its category
Most conventional microwave popcorn brands (Orville Redenbacher, Act II, Pop Secret) use similar PFAS-coated bags because the grease-resistant requirement is industry-standard. Non-microwave popcorn (stovetop or air-popped) and some brands experimenting with alternative barrier coatings avoid this exposure. SkinnyPop is not distinguished as a category leader in packaging safety.
If you buy it
Follow microwave instructions precisely; do not exceed recommended heating time, as excess heat can increase coating degradation and PFAS migration. Avoid puncturing the bag before cooking. Allow the bag to cool before opening to reduce vapor inhalation. If you consume microwave popcorn regularly, rotate brands or switch to stovetop popping to reduce cumulative PFAS exposure from food packaging.
