Kraft Paper Straws
Lower PFAS concern, kraft paper straws lack typical chemical coatings that introduce forever chemicals.
Kraft paper straws are made from a minimally processed plant material without inherent fluorochemical use. Unlike plastic straws or some coated single-use papers, uncoated kraft naturally resists some moisture without PFAS-based water-resistant treatments.

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
Kraft paper straws are made from virgin or recycled kraft pulp, a wood-fiber material processed with minimal chemical treatment. Uncoated kraft relies on the natural lignin in paper to provide structural integrity when wet. This simplicity means fewer synthetic additives that could leach into beverages compared to plastic or heavily coated alternatives. The main processing input is sodium hydroxide and sulfide during pulping, but residual amounts in finished straws are negligible.
The brand's record and disclosure
Naked Sprout does not publish detailed material sourcing, certifications, or third-party testing results on their website or marketing materials. No recalls, regulatory actions, or documented safety incidents are on record for this brand or product line. The brand's silence on PFAS stance or environmental sourcing is notable given market competition, but absence of transparency is not the same as absence of safety. Standard kraft paper production does not inherently introduce the hazards typical of competitor products.
How it compares in its category
Kraft paper straws occupy the middle ground: safer than plastic straws (which risk microplastics and BPA in some formulations) but less durable than bamboo or stainless steel alternatives. Unlike plastic straws coated with PLA or wax, kraft straws do not introduce synthetic polymer residues into beverages. Compared to bleached paper straws, kraft paper typically has lower bleach residue because the brown pulp requires less chlorine chemistry. They are comparable in safety profile to unbranded generic kraft straws.
If you buy it
Use straws within 30 minutes of contact with hot or acidic liquids (citrus, hot tea) as prolonged exposure can soften or fragment kraft fiber. Discard any straw showing visible breakdown, dark spots, or odor before use, as these may indicate mold colonization in storage. Store in a cool, dry place away from moisture to prevent fungal growth; kraft paper has no antimicrobial treatment. Single-use straws should not be washed and reused, as this accelerates fiber degradation and may increase fragmentation risk.
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.”
Mold and microbial growth
Uncoated kraft paper absorbs moisture and can support mold, mildew, or bacterial colonization if stored in humid conditions or contaminated during manufacturing. Risk is highest if packaging is breached or if straws are pre-wet before use.
Fiber fragmentation and pulp ingestion
Prolonged contact with hot, acidic, or alcoholic beverages can cause kraft fibers to separate and shed into drinks. While cellulose is not toxic, fragments may be unpleasant and could pose minor risk if aspirated by young children.
Ink and print adhesives on packaging
If Naked Sprout straws are packaged with printed labels or banding, soy-based or petroleum inks and adhesives may transfer if packaging contacts the straws. No specific data on Naked Sprout packaging composition is publicly available; standard practice involves food-grade inks but verification is not confirmed.
Chlorine and chemical pulping residues
Kraft paper production (sulfite or sulfate process) uses strong alkali but minimal chlorine compared to bleached pulp. Residual sodium hydroxide or sulfide in finished straws is below detectable levels in standard products, but raw material source is not disclosed by Naked Sprout.
Heavy metals in recycled paper feedstock
If Naked Sprout uses recycled kraft, contaminants such as lead or cadmium from previous product use may persist in pulp. No sourcing transparency is provided; risk is low but cannot be ruled out without certification data.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
