Compostable Food Storage Container 5ct vs 6 x 9 Fiber Container (Bottom) 300 per case: which is safer?
Matter Compostable Food Storage Container 5ct is the clear pick. 6 x 9 Fiber Container (Bottom) 300 per 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 .
- We flag Water-resistant coating migration (unspecified chemistry), Coating degradation and particulate leaching, Microorganism growth in uncoated fiber and Regulatory non-compliance or lack of FDA clearance documentation on the and not on the Matter.
- The Matter is Plant-based fiber pulp (compostable) where the is fiber-based container with unspecified water/grease-resistant coating, 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.
- We are less certain about the grade, at 35% confidence against 82%, 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 →
