What Great Value Flavored Microwave Popcorn is made of, ingredients and materials
Great Value microwave popcorn bags use paperboard lined with a grease-resistant polymer coating, almost certainly fluorinated (PFAS-based) to repel oil and moisture during storage and heating. This coating is engineered to remain stable under microwave temperatures (around 350F) but degrades over time or if the bag is punctured, creased, or stored in heat. The paperboard itself has no hazard of this kind on record, but the coating's composition and migration behavior are not disclosed by the brand, making independent verification impossible.
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
Paperboard bags with water and oil repellency almost universally use PFOA, PFOS, or replacement PFAS compounds. Brand has not disclosed the specific chemical or migration data, and industry studies show detectable PFAS in coated food contact papers.
Source, ATSDR ↗Coating degradation and leaching under heat
Microwave heating to 350F, repeated use, and bag abrasion can compromise fluorinated polymer integrity, increasing migration of coating breakdown products into popcorn. Long-term storage at elevated temperatures accelerates this process.
Microplastics
If the grease-resistant layer degrades or flakes due to moisture or heat stress, microscopic polymer and fluorochemical particles may contaminate popcorn, especially in bags with visible wear.
Source, EPA ↗What’s reassuring
Mineral oil or petrolatum residues in coating
Great Value bags do not appear to use mineral oil as a primary grease barrier, but formulation details are proprietary. No testing or recalls suggest this hazard for this specific product.
BPA & bisphenols
Paperboard ink and adhesives in microwave popcorn bags are not a documented source of BPA migration in peer-reviewed literature; coating chemistry dominates food-contact hazard profile for this product.

The brand's record and disclosure
Great Value (Walmart's private label) has not publicly disclosed the specific fluorochemical formulation or non-fluorinated alternatives for its popcorn bag linings. The brand has no documented sustainability certifications (e.g., GreenGuard, Cradle to Cradle) for food packaging and does not publish ingredient sourcing or chemical safety statements for grease-resistant coatings. No major recalls or safety actions specific to this product are on record, but silence on PFAS composition is consistent with industry-wide lack of transparency.
How it compares in its category
Most commercial microwave popcorn bags (including major brands like Orville Redenbacher, Pop-Secret) use fluorinated grease barriers; true PFAS-free alternatives are rare and typically labeled explicitly (e.g., some organic or eco-branded popcorn). Great Value's positioning as a budget option means cost, not safety, drives material choice. Consumers seeking lower PFAS exposure typically turn to stovetop popcorn in plain paper bags or loose kernels in glass bowls.
If you buy it
Inspect bags before use for tears, creases, or discoloration that indicate coating breakdown. Do not overheat or use a microwave setting above manufacturer instructions, as prolonged heat accelerates fluorochemical migration. Avoid storing bags in hot environments (above 70F for extended periods). If PFAS exposure is a personal health priority, this product does not meet that threshold; switch to loose kernel popcorn or brands with documented non-fluorinated coatings.
