Where these two actually differ

  • We flag Silicone or TPU degradation and leachates, Dye or pigment migration in glossy finish and Mold or bacterial growth in seals on the CAT and not on the Pela.
  • We flag Coating degradation and durability over time and Allergic contact dermatitis from plant fiber or resin on the Pela and not on the CAT.
  • The CAT is TPU or silicone dual-layer where the Pela is Flax fiber and plant-based resin blend, compostable, which is most of the difference in these two grades.
  • We are less certain about the CAT grade, at 35% confidence against 92%, 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 →
