Flaxstic Compostable Phone Case vs Liquid Screen Protector: which is safer?
Flaxstic Compostable Phone Case is the clear pick. Liquid Screen Protector carries a failing PFAS grade, and we never recommend buying a failing product.

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 Pela.
- We flag Volatile organic compounds (VOCs) and residual monomers, Coating durability and microflaking, Skin or eye sensitization from uncured or contact exposure and Inadequate application guidance and user error on the Pela and not on the Pela.
- The Pela is Flax fiber and plant-based resin blend, compostable where the Pela is Liquid nano-coating (unspecified polymer), which is most of the difference in these two grades.
- The gap is 50 points, wide enough that this is not a close call, and the Pela is the one to buy.
- We are less certain about the Pela grade, at 25% 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 →
