Katom · Grease-Resistant Paper Goods
Kraft Paper Sheets 24x24 / Without Center Cut / 500 Sheets per Case
Lower concern. Bare kraft paper rarely requires PFAS coatings.
Uncoated kraft paper sheets have minimal PFAS risk. No grease-resistant coating mentioned, typical for standard food-packaging kraft paper. Brand discloses no treatment.

The full breakdown
What it's made of and why it matters
Kraft paper is mechanically processed wood pulp without added coatings or chemical treatments in this uncoated variant. The manufacturing process breaks down wood fibers into strong, porous sheets suitable for food wrapping and packing. Uncoated kraft avoids the chemical additives (dyes, resins, glazes) that carry leaching risks in other paper products. Because it remains porous and absorbent, it does not concentrate contaminants the way sealed or laminated papers can.
The brand's record and disclosure
Katom is a commercial food-service supplier with no published sustainability certifications or chemical disclosure statements readily available. The company does not appear in major food-contact material recalls or safety controversies in public records. No third-party certifications (FSC, chlorine-free, GOTS equivalent for paper) are documented for this specific product line. Lack of transparency does not indicate hazard presence, but suggests limited independent verification of sourcing or bleaching methods.
How it compares in its category
Uncoated kraft sheets occupy the safest tier of food-contact paper products, alongside parchment and kraft-based food wraps. They avoid the microplastic and coating-degradation risks of plastic films and the heavy-metal contamination potential of colored or clay-coated papers. Coated kraft, wax paper, and plastic-lined alternatives introduce synthetic additives; bare kraft does not. For single-use food contact, uncoated kraft is a conventional and low-risk choice across the food service industry.
If you buy it
Store sheets in a cool, dry location to prevent moisture absorption and mold growth. Use directly for room-temperature and warm (not boiling-contact) food wrapping; kraft can soften or transfer ink if exposed to prolonged steam or oil immersion. Do not reuse sheets after direct food contact, as recycling food-contaminated kraft risks cross-contamination. Check each sheet visually for discoloration, mold, or odor before use, particularly if stored in humid conditions.
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.”
Bleach residues and chlorine compounds
Most commercial kraft papers are bleached with chlorine or chlorine dioxide to achieve whiteness and strength. No specific test data for Katom bleach method is published; residual chlorinated compounds in kraft are typically below food-contact thresholds but remain unverified for this product.
Ink migration from printing
This product is described as uncoated sheets without center cut markings, implying minimal or no printing. Blank kraft carries no ink hazard. If any lot contains printed branding, oil-based inks can migrate into fatty foods; visual inspection before use mitigates this risk.
Mold and bacterial growth
Kraft paper is porous and hygroscopic, absorbing ambient moisture. Poor storage in humid or warm conditions creates risk of mold colonization before use. This is a storage and handling risk, not an inherent material hazard, and is preventable through dry storage.
Ink or dye contamination in recycled fiber
If Katom's kraft is made partly from recycled paper stock, trace metals (copper, chromium from old inks) may persist in the pulp. No certification of virgin or recycled content is stated. Food-contact standard compliance typically ensures levels are safe, but absence of disclosure leaves this uncertain.
Lignin and tannin degradation products
Unbleached or lightly bleached kraft can shed small amounts of lignin (wood binder) into acidic or fatty foods over time, imparting color or odor. Katom product description does not specify bleach level, so degradation risk is not established for this specific variant.
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.
