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 Mold and microbial growth, Thermal degradation and structural failure and Fiber shedding or particle ingestion 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.
- These two are 5 points apart, close enough that price and fit should decide it rather than our grade.
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 →
