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 Microplastics migration when heated and Opacity loss and structural integrity over time 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) container, uncoated, 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: 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 →
