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
Microwave popcorn bag linings routinely contain fluorinated compounds for water and oil resistance. Migration to food is minimal under normal use but increases with bag damage, overheating, or repeated use. See separate PFAS grade (25/100) for detailed assessment.
Source: ATSDR ↗Coating degradation under heat stress
Overheating the bag or using damaged packaging can cause the inner lining to degrade or flake. While a single incident is unlikely to cause harm, fragments in popped kernels are a physical rather than chemical hazard. Proper adherence to microwave instructions minimizes this risk.
Mineral oil or paraffin in susceptor layer
Susceptor films may contain mineral oil or paraffin wax to improve heat distribution. Food contact is designed to be minimal, but migration increases if the susceptor is punctured or the bag overheats. No specific recalls or reports for Newman's Own, but the hazard class is present in the product design.
Microplastic shedding from bag lining
Synthetic polymer linings can shed microscopic fragments if worn, torn, or heavily stressed by heat. Risk is low under normal handling but increases with rough storage, freezing-thawing cycles, or extended shelf life. No specific data on Newman's Own bags, but inherent to the material class.
What’s reassuring
Ink or dye leachables from outer packaging printing
The outer cardboard box uses standard food-grade printing inks. No known issues reported for Newman's Own packaging in this regard, and outer materials do not contact food during normal use.
The full breakdown
What it's made of and why it matters
Newman's Own microwave popcorn bags are paperboard lined with a grease-resistant coating (likely fluorinated to repel butter oils) and a susceptor (metallicized film) that concentrates microwave heat to pop kernels. The inner lining prevents oil migration into the cardboard but is the same chemical system flagged for PFAS contamination. At typical microwave temperatures (around 400F at the bag surface), risk of coating breakdown or migration is low, but repeated or overheating use can compromise the barrier.
The brand's record and disclosure
Newman's Own does not publicly disclose whether their popcorn bag linings use PFAS-based or alternative grease-resistant technologies. The brand has no published commitments to phase out fluorinated coatings in food packaging. Requests for clarification on specific bag chemistry are not routinely answered in public materials. For a brand positioning itself on quality and transparency, this silence on a known industry practice is a notable gap.
How it compares in its category
Microwave popcorn bags across most major brands (including Orville Redenbacher, Act II, Pop Secret) use similar fluorinated or fluorine-containing greaseproof linings; Newman's Own is not an outlier. Popcorn popped on stovetop or in air poppers avoids bag-lined packaging altogether. Bag-free microwave popcorn options are rare and often more expensive, making this product typical rather than exceptionally risky within its niche.
If you buy it
Follow microwave instructions exactly; do not extend cooking time or use high-power settings that could overheat the bag and degrade the lining. Inspect the bag before use for tears or damage that could allow coating particles into food. Store in a cool, dry place away from direct heat or sunlight to prevent premature aging of the lining. If you microwave popcorn frequently (more than once weekly per household member), consider alternating with stovetop or air-popped options to reduce overall PFAS exposure from packaging.
