Where these two actually differ

  • We flag PFAS or other fluorinated water-repellent coatings, Coating leachates (unspecified chemistry), Microplastics from coating degradation and Migration of adhesives or binders used in pulp processing on the Dart Container and not on the Matter.
  • We flag Microbe/mold growth if stored damp and Cellulose degradation under repeated hot/wet stress on the Matter and not on the Dart Container.
  • The Dart Container is Molded fiber/paperboard with proprietary coating where the Matter is Plant-based fiber pulp (compostable), 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 Dart Container 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 →
