PossibleGrease and oil migration into food from degraded fiber
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 Karat.
- We flag Microbiological growth (mold, bacteria) on cellulose substrate and Grease and oil migration into food from degraded fiber on the Karat and not on the Matter.
- The Matter is Plant-based fiber pulp (compostable) where the Karat is Bagasse (sugarcane fiber), uncoated, which is most of the difference in these two grades.
- The gap is 30 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 →
