Zoro Select Kraft Paper 12 inch 900 Ft. 40 Lb. Basis Weight 900 ft. 12"
Lower concern. Plain kraft paper roll unlikely to contain PFAS.
Standard kraft paper roll from International Paper with no water-resistant coating mentioned. Bare kraft paper is inherently lower risk for PFAS contamination unless treated for grease resistance, which is not indicated here.

Why this grade

Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This is unbleached kraft paper, made from wood pulp processed using the kraft method, which involves minimal chemical treatment compared to bleached papers. Kraft paper's lignin content (the natural binder in wood) gives it strength and brown color without synthetic additives. For food contact, the key concern is whether processing chemicals or coatings migrate into food; unbleached kraft typically avoids the chlorine bleach and optical brighteners found in white papers, reducing chemical leachate risk.
The brand's record and disclosure
International Paper is a major commodity paper manufacturer with no public PFAS disclosure or transparency reports specific to kraft paper food-contact grades. The company has not faced documented food-safety recalls tied to kraft paper products. However, International Paper's general silence on food-contact coatings and processing chemicals means verification of per-roll specifications relies on indirect industry standards rather than brand transparency.
How it compares in its category
Unbleached kraft paper is considered a safer baseline in food wrapping compared to bleached kraft, coated papers, or plastic-lined alternatives because it avoids synthetic brighteners and coatings. The 40-pound basis weight is standard for general wrapping and is not associated with higher chemical load than lighter grades. This product sits at the lower-risk end of paper packaging due to minimal processing; specialty food papers with barrier coatings or recycled content can introduce higher contamination vectors.
If you buy it
Use for wrapping dry goods, baked goods, and room-temperature foods; avoid prolonged contact with fatty or acidic foods, which can accelerate minor lignin leaching. Store the roll in dry conditions to prevent mold growth and moisture damage. Do not use as a heat-resistant barrier for oven cooking above 400°F; kraft paper can char or decompose. Replace if visible discoloration, mold, or odor develops, though a 900-foot roll at household use rates typically has multi-year shelf life.
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 printing residues
This product is listed as unprinted plain kraft; no known reports of pigment or ink contaminants in plain rolls from International Paper. Risk would apply only if the specific roll sourced includes printed branding or date codes.
Mineral oil or paraffin coatings
Some kraft paper food-wrapping products include light mineral oil or paraffin coating for grease resistance; International Paper does not publicly disclose coating status for this grade, so presence cannot be ruled out without product specification sheet review.
Chlorine bleach or optical brightener residues
Unbleached kraft paper explicitly avoids the chlorine-based bleaching and fluorescent brightening agents used in white kraft, eliminating this migration pathway.
Microbial contamination (post-purchase)
Paper is hygroscopic and can harbor mold or bacteria if stored in damp conditions; this is a use-environment risk, not a manufacturing defect, and is reversible with proper dry storage.
Formaldehyde in processing resins
Kraft pulping does not typically use formaldehyde-releasing resins; the kraft process itself is lignin-based and does not require urea-formaldehyde or melamine-formaldehyde binders.
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.
