Where these two actually differ
- We flag Leachables from undisclosed grease-resistant coating, Thermal degradation and microplastic potential if overheated and Incomplete composting in non-industrial environments on the Eco-Products and not on the Solo.
- We flag Polystyrene monomer and oligomer leaching, Undisclosed grip-coating additives, Coating degradation and microplastics and Off-gassing and volatile organic compounds on the Solo and not on the Eco-Products.
- The Eco-Products is Plant-based compostable PLA coating where the Solo is polystyrene plastic (PS) with grip coating, which is most of the difference in these two grades.
- These two are level, 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 →
