What Hefty Supreme Foam Hinged Lid Containers is made of, ingredients and materials
Hefty Supreme containers are expanded polystyrene (EPS) foam with a grease-resistant coating applied to the interior surfaces. This coating is almost certainly fluorinated (PFAS-based) to repel oils and liquids, a standard industry practice for foam food packaging since the 1990s. Polystyrene itself is a known endocrine disruptor when heated or in contact with fatty foods, and the added coating's composition is not disclosed by the manufacturer.

No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Expanded polystyrene food packaging relies on fluorinated barrier coatings for water and grease resistance. Hefty's formula is proprietary and undisclosed, but migration to fatty or heated foods is a documented mechanism with PFAS chemistry.
Source, ATSDR ↗Styrene monomer leaching
Polystyrene foam degrades with age, heat, and solvent contact, releasing residual styrene monomers. FDA classifies styrene as a possible carcinogen and developmental concern; impact is highest with hot or fatty foods.
Microplastics
EPS foam is fragile and sheds particles during handling, stacking, and use. These micro- and nano-particles can be ingested with food, particularly with moist or crumbly contents.
Source, EPA ↗Coating delamination and unknown additives
The applied grease barrier may degrade, flake, or leach additives (plasticizers, surfactants, hardeners) into food. Without disclosure of coating chemistry, specific additives and their safety profiles cannot be assessed.
Endocrine disruptors
Polystyrene contains oligomers and residual monomers with estrogenic activity documented in animal studies. Risk increases in contact with acidic, fatty, or hot foods.

The brand's record and disclosure
Hefty (owned by Reynolds Consumer Products) does not publicly disclose the chemical formulation of coatings on its foam food packaging, nor does it publish safety testing data or PFAS content limits. The brand has made no statement acknowledging PFAS use in food containers. Without third-party certification or transparency commitments, there is no basis to verify the safety of these products.
How it compares in its category
Foam hinged clamshells are among the most problematic food packaging formats because they are disposable (no replacement option), impossible to verify for contaminants, and commonly used for high-fat foods (cheese, baked goods, fried items) that accelerate leaching. Rigid plastic (#1 PET or #5 PP) containers without foam and coating offer far better transparency and lower risk of PFAS exposure. Cardboard-lined or uncoated molded fiber alternatives eliminate the chemical coating risk entirely.
If you buy it
Do not use these containers for hot foods, fatty items, or acidic foods; migration increases with temperature and food chemistry. Never microwave or store in warm conditions. Once used, discard immediately; do not reuse. If cost is a constraint, consider uncoated rigid plastic (PET) deli containers or kraft cardboard takeout boxes sold in bulk, which avoid the fluorinated barrier chemistry altogether.
