World Centric Kraft Paper Straws
Lower-concern choice; PFAS-free certified but no independent lab test disclosure.
World Centric explicitly claims PFAS-free kraft paper straws and holds MADE SAFE certification, a credible third-party standard. However, the brand does not publish lab test results confirming absence of PFAS.
Brand says: “World Centric products are PFAS-free and certified by MADE SAFE.”

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
food packaging is a category where PFAS exposure is more common.
Third-party PFAS-free verification
Independently verified PFAS-free by a third party.
The full breakdown
What it's made of and why it matters
World Centric Kraft Paper Straws are made from kraft paper (mechanically and chemically processed wood pulp) with a water-based coating applied to reduce liquid penetration and structural degradation. Kraft paper itself is a well-established, compostable material with low toxicity. The water-based coating replaces older plastic-based or wax-based approaches and avoids conventional fluorochemical repellents (PFAS), though the specific binder chemistry of their coating is not publicly detailed.
The brand's record and disclosure
World Centric (operated by Packaging Service Co.) markets these straws as PFAS-free and compostable, and the brand is part of sustainability-focused supply chains. However, no independent laboratory test results for PFAS or coating composition are publicly disclosed on packaging or official statements reviewed. The brand's transparency on coating formulation (e.g., whether it contains other fluorine-free water repellents or binders) is limited, typical for commodity food service packaging.
How it compares in its category
Kraft paper straws are a middle ground: they avoid Teflon-type coating/PFOA concerns of some plastic straws and microplastic shedding risk, but degrade faster in cold or acidic liquids than plastic or bamboo alternatives. Many competitors (Aardvark, Footprint) also claim PFAS-free status. World Centric's straws are compostable under industrial conditions, which is a standard advantage across certified paper straw products in this category.
If you buy it
Use these straws for room-temperature or warm beverages; they soften within 20-30 minutes in cold or acidic drinks (citrus, soda, vinegar). Do not reuse; discard after single use. Store in a cool, dry place to prevent mold growth on paper. Check that your local compost facility accepts food-soiled paper products; home compost may be too cool. No cleaning or maintenance required.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Coating degradation and fiber shedding
Water-based coatings on kraft paper can degrade with extended contact with cold, acidic, or fatty liquids, potentially releasing small paper fibers into the beverage. This is a known limitation of paper straws generally, not specific contamination but a functional weakness.
Microbial growth if stored improperly
Kraft paper is hygroscopic and can absorb moisture. If stored in humid conditions, mold or bacterial colonies may develop on or within the paper before use. Proper dry storage at typical room conditions prevents this.
Ink or printing dyes on straws
No reports of heavy metal contamination or azo dye concerns in World Centric straws. Food-contact printing inks on these products are typically soy-based or mineral-oil-based and subject to FDA guidelines, but specific ink formulation is not publicly disclosed.
Residual chemical processing from kraft pulping
Kraft paper production uses sodium sulfide and hydroxide (pulping chemicals), but these are effectively removed during washing and bleaching stages. No established leaching of caustic residues from food-contact kraft paper has been documented in regulatory databases.
Water-based coating binder identity
The specific polymer or resin used in the water-based coating is not disclosed. While water-based coatings are generally safer than solvent-based alternatives, the absence of public ingredient detail limits independent assessment of potential allergens or minor contaminants.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
Formulations and coatings change between production runs. Always check the current label before buying.
Safer alternatives in Paper Straws
World Centric
Compostable Straws
Plant-based cellulose (PHA/PLA blend), compostable
Lower-concern choice; compostable material + explicit PFAS-free claim + third-party certifications reduce risk substantially.
✓Verified PFAS-free by a third party
Vegware
Compostable Standard Straws (6500ct)
Polylactic acid (PLA) bioplastic
Lower concern; compostable PLA straws with credible third-party compostability certs and explicit PFAS-free positioning.
✓Verified PFAS-free by a third party
Vegware
Green stripe Jumbo Vegware wrapped PLA
PLA (polylactic acid) compostable plastic
Lower concern; PLA itself carries minimal PFAS risk, and Vegware makes no intentional additions, but verify end-of-life composting.
