- We flag Grease-resistant coating composition (unknown chemistry) and Coating migration to fatty foods on the and not on the Matter.
- The Matter is Plant-based fiber pulp (compostable) where the is kraft paper with unspecified grease-resistant coating, 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 grade, at 35% confidence against 82%, because it discloses less.
