Where these two actually differ
- We flag Coating degradation and durability over time and Allergic contact dermatitis from plant fiber or resin on the Pela and not on the Tech21.
- We flag Volatile organic compound (VOC) off-gassing, Material degradation and leaching and Mold and bacterial growth in sealed seams on the Tech21 and not on the Pela.
- The Pela is Flax fiber and plant-based resin blend, compostable where the Tech21 is Thermoplastic elastomer (TPE) blend, composition unspecified, which is most of the difference in these two grades.
- We are less certain about the Tech21 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 →
