Hefty Supreme 3-Compartment Foam Plates 10 1/4" 200 ct.
Skip; foam with grease-resistant coating carries moderate PFAS concern and zero brand clarity.
Foam plates with an undisclosed water and grease-resistant layer typical of food-service foam. Hefty won't commit to PFAS avoidance, and no independent testing exists.

Material
expanded polystyrene foam with proprietary 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 treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Coating degradation and microplastic release
Grease-resistant coatings on EPS foam are known to wear, flake, and fragment under normal use and heat exposure. Fragments shed into fatty foods, sauces, and liquids; long-term ingestion risk is not quantified but fragments are non-digestible.
Styrene monomer leaching
Expanded polystyrene can release trace styrene (a suspected carcinogen by IARC) when in contact with fatty foods or warm liquids; risk increases with coatings that may be incompatible with foam chemistry. Hefty does not publish migration data.
Thermal degradation
EPS foam releases volatile organic compounds (VOCs) and styrene at temperatures above 140°F. Hot foods, microwaving, or dishwasher heat will degrade this product rapidly and increase chemical exposure.
Food contact substance transparency gap
No third-party testing or FDA approval statement published for the proprietary coating; it is unclear if it meets food contact substance regulations or if any non-compliant additives are present. Brand silence suggests low regulatory confidence.
What’s reassuring
BPA & bisphenols
No recalls or published data indicate BPA or phthalate leaching from this specific product. Polystyrene foam does not inherently contain these, but manufacturing residues are possible; not documented for Hefty.

What it's made of and why it matters
Hefty Supreme plates are expanded polystyrene (EPS) foam, a lightweight plastic made by puffing polystyrene with blowing agents. The proprietary grease-resistant coating applied to the surface is the primary concern: grease-resistant treatments on food-contact foam products commonly rely on fluorochemicals (PFAS compounds) to repel oils and prevent liquid penetration. This coating degrades with heat and mechanical wear, potentially releasing microplastics and coating fragments into food, especially fatty or hot foods.
The brand's record and disclosure
Hefty (Pactiv Evergreen) has not publicly disclosed the chemical composition of its proprietary coatings or committed to PFAS phase-out in single-use food service products. No third-party certifications (BPA-free, non-toxic, compostable) are marketed on this product. The brand has faced no major recalls tied to chemical leaching, but the silence on coating chemistry and PFAS presence is a red flag for consumers seeking transparency.
How it compares in its category
Coated foam plates occupy the middle ground of disposable dinnerware: cheaper than compostable molded fiber but with higher chemical exposure risk than plain paper plates or uncoated ceramics. Competing brands like Solo and AmazonBasics offer similar EPS products with identical coating concerns. Safer alternatives include uncoated molded-fiber (sugarcane-based) plates or washable ceramic/melamine dinnerware, which avoid both PFAS and microplastic risk.
If you buy it
Do not use for hot foods above 140°F (60°C); foam degrades and leaches more readily at temperature. Avoid microwaving, which accelerates coating breakdown. Do not reuse; EPS foam is single-service only and coating wear is invisible. Inspect plates for visible cracks or discoloration before use; discard damaged stock. Consider these a last-resort option for outdoor events only, not regular household use.
