Where these two actually differ
- We flag Thermal degradation and chemical release at use temperatures on the Eco-Products and not on the Fabri-Kal.
- We flag Microplastic migration (heat exposure), Styrene monomer leaching (PS-specific) and Off-gassing or odor (new material smell) on the Fabri-Kal and not on the Eco-Products.
- The Eco-Products is Compostable resin (PLA/PBAT blend, plant-based) where the Fabri-Kal is polypropylene (PP) and polystyrene (PS) rigid plastics, which is most of the difference in these two grades.
- The gap is 30 points, wide enough that this is not a close call, and the Eco-Products is the one to buy.
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 →
