Biodegradable 6x6 Take Out Food Containers with Clamshell Hinged Lid Mi vs Compostable Food Storage Container 5ct: which is safer?

Where these two actually differ

• We flag Microplastic/fiber shedding from material breakdown, Processing chemical residues (bleach, formaldehyde resins, glues), Moisture absorption and microbial growth if stored improperly and Thermal degradation and leaching at high temperatures on the Avant Grub 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 Avant Grub.
• The Avant Grub is Bagasse (sugarcane fiber), compostable/biodegradable formulation where the Matter is Plant-based fiber pulp (compostable), 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.
