Where these two actually differ

  • We flag TPU degradation and yellowing from UV exposure, Thermal deformation under heat, Gasket and seal material durability and Microplastic shedding from case wear on the Ghostek 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 Ghostek.
  • The Ghostek is TPU/polycarbonate blend 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 Ghostek grade, at 42% 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 →
