Katbite Unbleached Parchment Paper Sheets
Lower risk likely, but manufacturer won't discuss PFAS treatment.
Unbleached parchment typically uses silicone rather than fluorochemical coatings. Hefty refuses to disclose PFAS status, and direct inquiry is your best option for full assurance.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Silicone coating thermal degradation
Silicone coatings can degrade or leach oligomers if heated consistently above 400-420F or exposed to prolonged high heat. Katbite product literature does not specify exact upper temperature limit or residual oligomer safety data. Risk is low for standard baking (250-375F) but rises with broiling or direct heat contact.
PFAS
Silicone and paper sizing agents may contain fluorinated compounds for water and oil resistance. Hefty does not disclose PFAS content or avoidance. Risk is inherent to the category; unbleached status does not exclude PFAS use in the coating layer. See separate PFAS grade (25/100) for detail.
Source, ATSDR ↗What’s reassuring
Unbleached pulp contaminants (dioxins, furans)
Unbleached wood pulp historically carries lower dioxin loads than chlorine-bleached paper. No reported contamination in Katbite or Hefty parchment products on record. FDA food-contact paper regulations set limits, and unbleached parchment generally meets these, but manufacturer provides no third-party test summary.
Ink or print residue from labeling
Katbite sheets are typically unlabeled or carry minimal printing. No reported migration of label ink into food. Risk is negligible if sheets are used as packaged and ink does not contact the cooking surface directly.
Mold or bacterial growth in storage
Unbleached paper is more susceptible to mold than bleached if stored in damp conditions, but Katbite sheets in sealed packaging are unlikely to develop microbial contamination before use. Once opened, store in dry conditions to prevent mildew odor or visible growth.
The full breakdown
What it's made of and why it matters
Katbite unbleached parchment is wood pulp (typically kraft paper) coated with food-grade silicone. Unbleached means no chlorine-based whitening agents were used in pulping, reducing the theoretical burden of dioxin precursors present in some bleached papers. The silicone coating is the functional barrier, it withstands heat up to roughly 420-450F (210-230C) before degradation risk rises, and it prevents direct contact between food and paper fibers. Unlike traditional bleached parchment, unbleached versions may yellow or brown slightly over time or at higher temps, but this is cosmetic, not a safety signal.
The brand's record and disclosure
Hefty (maker of Katbite) has no published PFAS policy or transparency statement regarding parchment coatings. The parent company (Reynolds Consumer Products) does not publicly disclose PFAS treatment of this product line. No recalls specific to Katbite parchment for chemical leaching are on record with FDA or CPSC. This silence is typical for the budget parchment segment and does not confirm PFAS presence, but it prevents independent verification of coating safety claims.
How it compares in its category
Unbleached parchment sheets occupy the lower-cost, minimalist segment. Premium brands (e.g., If You Care, Baking Freedom) often provide third-party testing or explicit PFAS-free claims; Katbite does not. Versus reusable silicone mats, parchment is single-use but avoids the durability and replacement costs of mats. Versus wax paper, parchment handles higher heat (wax melts above 350F). Versus bare pan cooking, parchment offers lower concern for non-stick coatings and cleanup, though not essential.
If you buy it
Use Katbite sheets for baking between 300-400F; avoid broiling or direct flame. Inspect sheets before use for tears or stains, and discard any with visible degradation or browning at edges (sign of prior overheating). Do not reuse sheets after high-heat cooking or if oil saturation is heavy. Store in a cool, dry place away from heat and light to prevent silicone brittleness. For frequent baking, consider reusable alternatives or brands with PFAS disclosure to reduce uncertainty.
