Where these two actually differ
- We flag Fluorinated grease-resistant coating (PFAS family), Non-fluorinated coating leachates (if silicone or proprietary alternative), Ink or adhesive contamination from printing and Thermal degradation of coating during hot-food contact on the Burger King and not on the Burger King.
- We flag Grease-resistant coating migration (non-PFAS components), Unknown additive content in vintage coating, Paper substrate degradation over decades and Formaldehyde-based adhesive or sizing on the Burger King and not on the Burger King.
- The Burger King is paper with grease-resistant coating where the Burger King is Paper with grease-resistant coating (unspecified), 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: 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 →
