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 Pactiv Evergreen.
- We flag Phthalates and plasticizers, Microplastics from degradation, Thermal degradation and volatile organic compounds (VOCs) and Chemical migration into food on the Pactiv Evergreen and not on the Matter.
- The Matter is Plant-based fiber pulp (compostable) where the Pactiv Evergreen is MFPP (multi-layer polypropylene) hinged clamshell with venting, 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 Pactiv Evergreen grade, at 45% 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 →
