Where these two actually differ
- We flag Monomer and oligomer leaching (PLA), Undisclosed additives in proprietary blends, Thermal degradation and fume release and Microplastics from degradation during storage or washing on the 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 .
- The is Compostable bioplastic (likely PLA or PBAT blend) 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.
