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 Coating composition (PFAS status unknown), Polymer coating migration or degradation, Recycled fiber contaminants (if applicable) and Ink or dyes in external print on the Solo and not on the Eco-Products.
- The Eco-Products is Plant-based compostable PLA coating where the Solo is paperboard with unspecified water/grease-resistant coating, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Eco-Products is the one to buy.
- We are less certain about the Solo grade, at 45% confidence against 78%, because it discloses less.
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 →
