World Art Hot Cups 4oz vs Dart Container Corporation Solo Cup Polycoated Hot Paper Cups: which is safer?

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 Fluorinated polymer migration (PFAS-family), Plastic/polymer coating degradation over time, Formaldehyde or other volatile organic compounds from adhesives and Microplastics from coating wear on the Solo and not on the Eco-Products.
• The Eco-Products is Plant-based compostable PLA coating where the Solo is paper with polycoated (plastic/wax) water barrier, 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.
