What Great Value Extra Butter Flavored Popcorn is made of, ingredients and materials
Great Value Extra Butter Flavored Microwave Popcorn comes in a paper/kraft bag lined with a grease-resistant coating, almost certainly fluorinated (PFAS-based) to repel butter oils during storage and heating. The bag is designed to withstand microwave temperatures (around 350-400°F briefly) without the coating breaking down and releasing particles into the popcorn. The butter flavoring itself is typically a blend of diacetyl-free compounds (diacetyl caused 'popcorn lung' in workers; largely phased out by major brands after 2000s recalls), making inhalation risk from the flavoring low for consumers.
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 almost universally use fluorinated coatings; this product has not confirmed PFAS-free status. Migration into popcorn during heating is possible at low levels but occurs at highest rates if bag is damaged or overheated.
Source, ATSDR ↗Microplastics
If the grease-resistant layer flakes or degrades under repeated or excessive microwave heat, small particles may enter the popcorn; no specific reports for Great Value, but this is a known physics risk for all synthetic polymer-lined food bags.
Source, EPA ↗What’s reassuring
Diacetyl or butter-flavoring inhalation risk
Diacetyl (linked to 'popcorn lung' in workers) has been absent from major popcorn brands since ~2007; Great Value popcorn is formulated without it. Consumer inhalation risk from this product is not established.
Ink or adhesive leachates from bag printing
Food-contact inks and adhesives on microwave popcorn bags are FDA-regulated; no recalls or hazard alerts specific to Great Value exist. Standard compliance is assumed but not independently verified by third parties.
Allergen cross-contamination or undisclosed ingredients
Great Value products are manufactured by various suppliers; labeling typically notes tree nuts and soy if present. No pattern of mislabeling specific to this SKU is on record.
How is this PFAS grade calculated?
The brand's record and disclosure
Great Value (Walmart's private label) has not publicly disclosed PFAS reduction targets or phased-out these coatings in microwave popcorn packaging as of available records. Walmart has made broader sustainability commitments but remains silent on fluorinated grease-resistant coatings in food contact materials. No product recalls or safety controversies specific to this item are on record. The brand's transparency on food packaging chemistry lags competitors like Orville Redenbacher, which markets PFAS-free options.
How it compares in its category
Microwave popcorn as a category relies heavily on fluorinated coatings; this product is typical, not an outlier. Stovetop popcorn in non-coated bags or air-popped alternatives present lower concern for PFAS exposure. Some premium brands (Act II, Orville Redenbacher) now offer PFAS-free microwave versions, though at higher cost and with less butter flavoring intensity. Great Value's pricing advantage comes partly from cost-cutting on packaging chemistry.
If you buy it
Use as directed, heat in microwave at power/time specified on bag; do not overheat or allow bag to smoke, as this increases coating degradation. Avoid tearing or puncturing the bag before cooking. Do not reuse the bag. Minimize frequency if PFAS accumulation is a concern (butter-flavored popcorn eaten weekly vs. monthly makes a difference in cumulative fluorinated compound exposure). Consider switching to stovetop popcorn or PFAS-free microwave brands if you consume popcorn regularly.
