Where these two actually differ
- We flag Thermal degradation and chemical release at use temperatures on the Eco-Products and not on the ProPlanet.
- We flag Fluorinated grease-resistant coating (undisclosed chemistry), Coating degradation and microplastic shedding and Unlabeled or unclear temperature limits on the ProPlanet and not on the Eco-Products.
- The Eco-Products is Compostable resin (PLA/PBAT blend, plant-based) where the ProPlanet is Polypropylene with 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 ProPlanet grade, at 45% 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 →
