Compostable Food Storage Container 5ct vs Soup Food Containers w/Vented Lids: which is safer?
Matter Compostable Food Storage Container 5ct is the clear pick. Huhtamaki Soup Food Containers w/Vented Lids 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 Huhtamaki.
- We flag Fluorochemical (PFAS) coating migration, Thermal breakdown of coating, Microplastic and fiber shedding and Coating adhesion loss over time on the Huhtamaki and not on the Matter.
- The Matter is Plant-based fiber pulp (compostable) where the Huhtamaki is Molded fiber/paperboard with liquid repellent coating (likely fluorochemical), 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 Huhtamaki grade, at 42% 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 →
