What Skinnypop Microwave Sea Salt Popcorn is made of, ingredients and materials
Skinnypop microwave popcorn uses a paper/paperboard bag lined with a grease-resistant coating to prevent oil from soaking through during cooking. This lining is the likely source of PFAS chemicals, which are fluorinated compounds used to repel grease and water in food packaging. The bag is heated directly in a microwave, creating conditions under which PFAS can migrate into the popcorn, especially into the oil and seasonings. Once consumed, some PFAS accumulate in the human body because they do not break down naturally.
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
Microwave popcorn bags commonly use fluorinated grease-resistant coatings; Skinny Pop does not disclose whether its bags contain PFAS, but the industry standard strongly suggests they do. Heat during microwaving increases the likelihood of migration into food.
Source, ATSDR ↗BPA & bisphenols
Paper bag linings sometimes use epoxy-based or bisphenol adhesives to bond layers; Skinny Pop has not published lining composition, so presence cannot be ruled out, though major manufacturers have largely phased out BPA in food contact.
Source, FDA ↗Phthalates
Exterior printing inks on popcorn bags may contain phthalate-based plasticizers; however, these are exterior-facing and would not directly contact food unless the bag tears or ruptures during cooking.
Source, ATSDR ↗What’s reassuring
Microplastic or paper fibers in product
No recalls or documented incidents of bag material degradation or fiber shedding into Skinnypop popcorn have been reported. Paper-based bags are generally stable at typical microwave temperatures.
Oil oxidation from packaging interaction
The bag lining is designed to resist oil and prevent rancidity; no known safety hazard from bag materials affecting oil quality has been documented for this product.
How is this PFAS grade calculated?
The brand's record and disclosure
Skinny Pop has not publicly disclosed the composition of its bag lining or confirmed whether fluorinated coatings are used. The brand has not published statements on PFAS reduction, sourcing standards, or plans to transition to alternative greaseproofing materials. No major recalls or safety violations are on record for Skinny Pop specifically, but the company's silence on this known industry practice suggests low transparency. Industry peers have begun phasing in non-fluorinated alternatives, yet Skinny Pop has not announced similar initiatives.
How it compares in its category
Most microwave popcorn bags sold in the US use fluorinated coatings, making Skinnypop typical rather than exceptional in this regard. Some premium and organic brands (e.g. Organic Valley, lesser-known niche producers) have switched to linings or paper-based solutions without known PFAS linkage, though these are less widely available and often more expensive. Stovetop popcorn in bulk avoids the packaging issue entirely. Overall, Skinnypop occupies the mainstream convenience category where PFAS use remains standard practice.
If you buy it
Follow package microwave instructions exactly; do not overheat or deliberately expose the bag to extreme heat, as this may increase PFAS migration. Do not reuse the bag or store popcorn in it after cooking. If budget allows, rotate Skinnypop with stovetop bulk popcorn or PFAS-free alternatives to reduce cumulative PFAS intake. Consider this product an occasional convenience item rather than a dietary staple, particularly for children and pregnant people, who are more sensitive to PFAS accumulation.
