Kraft Bread Bags
Lower-concern choice; plant-based coating replaces synthetic water barriers.
Notpla's bread bags use compostable plant-based cellulose coating instead of fluorochemical water-resistance treatments. The brand explicitly positions these as PFAS-free and holds credible compostability and forestry certifications.
Brand says: “PFAS-free packaging; made from sustainably sourced wood pulp with plant-based coatings”

Independently verified PFAS-free by a third party.
The full breakdown
What it's made of and why it matters
Notpla Bread Bags use a plant-based cellulose coating instead of traditional fluorinated polymers (PFAS) or polyethylene, which reduces exposure to persistent synthetic chemicals. Cellulose is derived from plant fibers and is inherently biodegradable, meaning the coating breaks down naturally rather than accumulating in the environment or food. The bag substrate is likely kraft paper (unbleached or bleached cellulose fiber), chosen for breathability and grease resistance without synthetic barriers. This material class avoids the leaching concerns associated with petroleum-based coatings while maintaining functional water and grease barriers.
The brand's record and disclosure
Notpla is a UK-based sustainable packaging company with explicit PFAS-free positioning and transparency about material sourcing; the company markets compostability and plant-based coatings as core values. No major safety recalls or regulatory violations are on record for this product. The brand provides basic ingredient disclosure and emphasizes third-party certification pathways (such as compostability standards like EN 13432), though detailed heavy metals or contaminant testing data is not publicly available. Independent verification of all claims (e.g., absence of non-intentional contaminants in cellulose) is limited to industry standard certifications rather than direct product testing.
How it compares in its category
Typical bread bags (polyethylene, coated kraft, or PFAS-lined) prioritize water and grease resistance through chemical barriers that persist in the body and environment; Notpla's plant-based cellulose sits at the safer end of the spectrum by eliminating that trade-off. Most conventional bakery bags either use PFAS, silicones, or plasticizers (phthalates) to achieve barrier properties; cellulose-coated alternatives are less common but growing. The compostability claim is genuinely distinctive and reduces end-of-life toxicity concerns. Performance trade-offs (slightly lower grease resistance or shelf life) are offset by lower chemical hazard profile.
If you buy it
Store in a cool, dry place away from direct sunlight to preserve the cellulose coating and prevent premature degradation. Do not microwave or expose to high heat, as cellulose coatings are not heat-stable and may degrade, potentially releasing coating fragments into food. Replace bags if the coating visibly cracks, peels, or becomes sticky, as loss of barrier function defeats the product's purpose. Compost according to local guidelines (EN 13432 certified bags require industrial composting conditions, typically 55-60 degrees C for 12+ weeks); home composting may be slower or incomplete.
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.”
Cellulose coating degradation over time
Plant-based cellulose coatings are less chemically stable than Teflon-type coating or polyethylene and may crack, peel, or become sticky with age, moisture, or temperature fluctuation. No reported failures in normal use, but degradation risk increases if bags are stored improperly or reused frequently.
Non-intentional contaminants in cellulose feedstock (heavy metals, pesticide residues)
Agricultural cellulose can carry trace heavy metals or agrochemical residues depending on source and processing; Notpla does not publicly disclose contaminant testing data. Risk is present for any plant-derived material but not elevated relative to other food-contact cellulose products on market.
Bleach residues in kraft paper substrate
If the kraft paper is bleached (unconfirmed for this product), residual chlorine compounds or chlorinated organic compounds may migrate to food at trace levels. Notpla's materials are not explicitly labeled as unbleached, so bleach residue presence cannot be ruled out without direct testing.
Microplastic shedding from coating
Cellulose is not a plastic and does not fragment into microplastics; however, if coating degrades into small particles, they would biodegrade naturally. No evidence of particle shedding from plant-based cellulose coatings in normal use.
Inadequate grease or moisture barrier if coating is thin or defective
Plant-based cellulose provides lower barrier performance than PTFS or polyethylene and may allow faster grease or moisture penetration, potentially affecting product freshness. This is a functional rather than toxicological risk but may reduce shelf life or lead to mold growth if bags are reused improperly.
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.
