What Great Value Light Butter Flavored is made of, ingredients and materials
Great Value microwave popcorn bags are paper/paperboard lined with a grease-resistant coating, typically applied to the interior surface to contain oil and butter flavoring during heating. This coating is where PFAS chemicals are likely present, since fluorinated barriers are industry-standard for grease resistance in single-use food packaging. The bag's structure means the coating makes direct contact with popcorn during the high-heat microwave process, creating potential for chemical migration into the 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
Fluorinated barrier coatings are standard in microwave popcorn bags to repel grease; PFAS is the typical chemistry. Migration risk increases with microwave heating. This product's coating composition is not disclosed.
Source, ATSDR ↗Coating degradation and migration during heating
Microwave heat can weaken polymer bonds in the bag's interior lining, increasing the likelihood that coating components migrate into the popcorn, especially if the bag is overheated or punctured.
What’s reassuring
PFAS
Paper bags typically use soy or mineral oil-based inks and food-safe adhesives; no specific safety alerts exist for Great Value bags, but ingredient sourcing and QA are not transparently disclosed.
Source, ATSDR ↗Microplastics
Properly functioning bags do not shed particles into popcorn under normal use. Risk is theoretical only if the bag is visibly torn, burned, or severely degraded before use.
Source, EPA ↗Allergen cross-contamination during manufacturing
Great Value product lines share manufacturing facilities with other foods; no recalls for allergen contamination in this specific product are on record, but shared-line risk exists for tree nuts and dairy depending on facility.
The full breakdown
The brand's record and disclosure
Great Value (Walmart's private label) has not publicly committed to eliminating PFAS from food packaging or disclosed what grease-barrier chemistry it uses. Walmart as a corporation has announced some supplier expectations around "chemicals of concern" but has not singled out PFAS in microwave popcorn bags as a priority. No recalls or safety statements specific to this product are on record, and the brand does not provide ingredient transparency for bag coatings to consumers.
How it compares in its category
Most conventional microwave popcorn bags (including name brands like Orville Redenbacher and Act II) use similar fluorinated grease-resistant coatings, making Great Value typical rather than worse. However, some brands now market PFAS-free alternatives using non-fluorinated barrier technologies, though these remain niche and higher-priced. Great Value's lack of disclosure about coating chemistry places it in the majority of budget-tier products, which rarely proactively communicate PFAS status.
If you buy it
Follow microwave instructions exactly; do not exceed recommended heating time, as higher temperatures may increase chemical migration. Store unopened bags in a cool, dry place away from heat or direct sunlight, which can degrade the coating. Consider using it as an occasional convenience rather than a staple. If concerned about PFAS exposure, switching to stovetop popping or buying PFAS-free popcorn products is a lower-risk alternative.
