Compostable Food Storage Container 5ct vs Kraft PLA-Lined Compostable #4 Take-Out Container 7 3/4" x 5 1/2" x 3 1/2" - 160/Case: which is safer?
Matter Compostable Food Storage Container 5ct is the clear pick. New Roots Kraft PLA-Lined Compostable #4 Take-Out Container 7 3/4" x 5 1/2" x 3 1/2" - 160/Case carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Microbe/mold growth if stored damp and Cellulose degradation under repeated hot/wet stress on the Matter and not on the New Roots.
- We flag Fluorochemical coatings (non-PFAS synthesis), PLA oligomer leaching, Thermal degradation and structural failure and Microplastic shedding from kraft fiber breakdown on the New Roots and not on the Matter.
- The Matter is Plant-based fiber pulp (compostable) where the New Roots is PLA bioplastic with kraft paper lining, which is most of the difference in these two grades.
- The gap is 75 points, wide enough that this is not a close call, and the Matter 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 →
