Where these two actually differ
- We flag Mold or microbial growth from moisture and Paper fragmentation ingestion on the Aardvark and not on the Straws PAPER.
- We flag PFAS in water-resistant coating (graded separately above), Coating degradation and unknown leachables and Microbiological growth (internal tube) on the Straws PAPER and not on the Aardvark.
- The Aardvark is paper (uncoated or standard coating) where the Straws PAPER is paper with water-resistant coating (composition unspecified), 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 Aardvark is the one to buy.
- We are less certain about the Straws PAPER grade, at 45% confidence against 72%, because it discloses less.
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 →
