Compostable Clear Clamshell Hinged Food vs Supreme Large Sandwich Foam Hinged Lid Containers: which is safer?
Eco-Products Compostable Clear Clamshell Hinged Food is the clear pick. Hefty Supreme Large Sandwich Foam Hinged Lid Containers carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Thermal degradation and chemical release at use temperatures on the Eco-Products and not on the Hefty.
- We flag Styrene monomer and oligomers leaching, Microplastic particulate shedding, Unspecified grease-resistant coating leachates and Off-gassing of volatile organics (VOCs) on the Hefty and not on the Eco-Products.
- The Eco-Products is Compostable resin (PLA/PBAT blend, plant-based) where the Hefty is Expanded polystyrene foam with unspecified grease-resistant coating, which is most of the difference in these two grades.
- The gap is 75 points, wide enough that this is not a close call, and the Eco-Products is the one to buy.
- We are less certain about the Hefty grade, at 35% confidence against 78%, because it discloses less.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
