Orville Redenbacher's Kettle Corn Microwave Popcorn
Skip until brand discloses PFAS status of bag coating.
Orville Redenbacher microwave popcorn bags likely contain grease-resistant fluorochemical coatings typical of the category, but the brand makes no public PFAS disclosure. Lab data unavailable.

Material
paper/paperboard popcorn bag with grease-resistant coating
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
PFAS
FDA and academic studies confirm that microwave heating of PFAS-lined popcorn bags causes fluorochemicals to migrate into the food, particularly the oily popcorn kernels. Long-term accumulation in the body is a concern; Orville Redenbacher's does not disclose whether it uses legacy or newer formulations.
Source: ATSDR ↗Thermal degradation of coating polymers
Paper-based food packaging coatings can break down under repeated or prolonged microwave heat, potentially releasing unidentified polymer fragments or unreacted precursor chemicals into the food.
Microplastics
If the Teflon-family coating degrades or flakes during heating or storage, microscopic particles may end up in the popcorn; the frequency and health impact of this pathway are not well quantified for this specific product.
Source: EPA ↗Residual monomers and processing aids in coating
Manufacturing of PFAS-based polymers can leave trace unreacted fluorochemicals or surfactants in the coating matrix; these may leach at low levels during use, though brand-specific data is not publicly available.
Lack of packaging transparency
The brand does not list the specific grease-barrier chemistry on the package or website, preventing consumers from making an informed choice and indicating a broader industry practice of concealing known PFAS use.
The full breakdown
What it's made of and why it matters
Orville Redenbacher's Kettle Corn microwave popcorn is sold in a paper/paperboard bag lined with a grease-resistant coating to prevent oil migration and maintain product freshness during storage and heating. This coating is typically a fluorochemical polymer (PFAS-based), which resists both water and oil but does not break down in the environment or your body. When the bag is heated in a microwave, the coating can migrate into the popcorn, especially the oily kernels, at rates that increase with temperature and time.
The brand's record and disclosure
Orville Redenbacher's parent company (now owned by Conagra Brands) has not made public commitments to disclose or eliminate PFAS from popcorn bag coatings, nor has the brand responded to consumer inquiries about coating chemistry. The popcorn industry as a whole has faced FDA scrutiny over PFAS migration from microwave bag linings since at least 2016, yet most brands, including this one, continue to use legacy formulations without transparent ingredient labeling. No major certifications (organic, non-GMO verified, etc.) cover PFAS avoidance in packaging.
How it compares in its category
Most microwave popcorn bags on the market still use PFAS-based grease barriers; this product is not exceptional in that regard but also not ahead of safer alternatives. Stovetop popcorn (kernels in a pot or air popper) avoids the bag-coating issue entirely. A small number of brands now use non-fluorinated grease barriers or paper-only bags, though availability is limited; these represent a meaningfully safer option if sourcing friction is acceptable.
If you buy it
Do not rely on this as a routine snack; reserve it for occasional use only. Follow microwave time instructions precisely and avoid overheating, as longer heating increases PFAS migration risk. Store unopened bags away from heat and sunlight, as environmental stress can accelerate coating breakdown. Consider stovetop popcorn or air-popped alternatives as your primary option to reduce cumulative PFAS exposure from food packaging.
