Where these two actually differ
- We flag Thermal degradation and chemical release at use temperatures on the Eco-Products and not on the Restaurantware.
- We flag Grease-resistant coating leaching (likely fluorinated compounds), Microplastics shedding, Thermal degradation of coating under microwave or oven use and Limited recyclability due to coating on the Restaurantware and not on the Eco-Products.
- The Eco-Products is Compostable resin (PLA/PBAT blend, plant-based) where the Restaurantware is Polypropylene (PP) with undisclosed 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 Restaurantware grade, at 45% confidence against 78%, because it discloses less.
Both products run through the same public rubric: 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 →
