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 Fiber degradation and microparticle shedding and Mold or bacterial growth if stored damp 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 plant fiber blend (molded fiber), 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 →
