World Centric 8 in. Kraft Paper Straws - Brown (50/Pack)
Lower concern, uncoated kraft paper straws typically avoid PFAS, but brand makes no explicit claim.
World Centric's kraft paper straws are made from plain kraft paper with no stated water-resistant coating or treatment. Kraft paper alone does not require PFAS to function. However, the brand does not publicly disclose PFAS status or testing, leaving some uncertainty about any manufacturing additives or trace contamination.

No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
These are kraft paper straws made from unbleached or minimally processed wood pulp, with no plastic coating or lamination layer. Uncoated kraft paper does not typically contain fluorinated compounds or other synthetic additives that migrate into beverages. The brown color comes from the natural lignin in kraft pulp rather than added dyes, which further reduces chemical leaching risk compared to bleached or dyed alternatives.
The brand's record and disclosure
World Centric is known for compostable food service products and holds certifications including BPI (Biodegradable Products Institute) compostability and GFSI compliance. The brand does not publish explicit third-party testing data or public statements about PFAS presence or absence in their straws. No recalls, contamination incidents, or regulatory actions against World Centric kraft straws are on public record.
How it compares in its category
Uncoated kraft paper straws are among the lowest-chemical-risk straw options. They are safer than most plastic straws (which may contain BPA or phthalates) and comparable to or slightly less processed than other unbleached paper brands. Some competitors market explicitly PFAS-free testing; World Centric's silence is a transparency gap but not evidence of contamination.
If you buy it
Use these straws in cold or room-temperature beverages only; hot liquids can soften uncoated kraft paper and potentially accelerate minor fiber shedding. Replace straws if they begin to visibly deteriorate or soften. These straws are designed for single-use and compost well in industrial facilities; home composting is slower. Store in a dry place to prevent mold or mildew before use.
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.”
Ink or dye leaching
Brown kraft paper straws typically use no added dyes; the color is natural lignin. No published incidents of ink migration from World Centric kraft straws into beverages.
Fiber or pulp ingestion / microparticle shedding
Uncoated paper straws can shed fine fibers when exposed to prolonged moisture or hot liquid. Shedding is minor and not toxic, but consumers may notice visible particles in beverages; this is a sensory rather than toxicological issue.
Mold or microbial contamination
Paper straws are hygroscopic and can support mold growth if stored in damp conditions or if straws become damp before use. Proper dry storage minimizes risk; no specific contamination incidents reported for World Centric brand.
Bleach or chemical processing residue
These straws are described as kraft paper (unbleached or brown), which implies minimal chlorine-based bleaching. No public test data on residual processing chemicals is available from the brand.
Heavy metals in paper pulp
Wood pulp and recycled paper can potentially carry trace heavy metals if sourced from contaminated recycled feedstock. No testing or incidents specific to World Centric straws are on record, and kraft virgin pulp sources typically have lower metal risk than recycled alternatives.
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.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
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.
