What Heavy Duty Unbleached Paper Sheets is made of, ingredients and materials
The brand's Heavy Duty Unbleached Parchment Paper is cellulose fiber paper coated with food-grade silicone to create a non-stick surface. Unbleached means it avoids chlorine-based whitening agents used in conventional parchment, reducing exposure to bleach byproducts. The silicone coating is the functional ingredient that prevents sticking and releases at higher temperatures than the paper itself (typically stable to 420-450°F depending on brand formulation).
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 degradation at high heat
If parchment is heated above 450°F or used under broiler, the silicone layer may break down and release volatile organic compounds (VOCs). The brand's product documentation does not specify temperature limits, so users must infer from standard parchment safety guidance.
Microplastics
Repeated heating and mechanical friction can cause silicone particles to fragment into food, especially if the coating is thin or poorly bonded. No testing data is public for this specific product, but it is a general risk for lower-cost silicone-coated papers.
Source, EPA ↗What’s reassuring
Chlorine residues from processing
The unbleached designation reduces risk compared to conventional parchment. No recalls or reports of chlorine contamination in parchment have been documented.
Ink or dye transfer from printed side
Parchment sheets are typically printed with branding or grid lines on the non-contact side only. No contamination reports exist, but contact with printed surfaces should be minimized during baking.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand does not publish detailed safety certifications or ingredient disclosures specific to this parchment product on their website. The company has not made public statements about PFAS testing or reduction in baking paper products, placing it in the silent/non-committal category alongside most retailer store brands. No safety recalls or public health warnings have been issued for this product line.
How it compares in its category
Unbleached parchment presents lower concern than bleached alternatives because it avoids dioxin formation risk from chlorine treatment. The brand's Heavy Duty version is mid-market, better than ultra-cheap parchment that may have thinner coatings or degradation issues, but without third-party testing certifications (FSC, Rainforest Alliance) that some premium brands carry. Most silicone-coated parchments in this price range have similar PFAS uncertainty and coating stability profiles.
If you buy it
Use sheets for dry baking (cookies, pastries, roasted vegetables) up to 420°F; monitor heating above that threshold as silicone can degrade and emit fumes if overheated. Replace sheets when coating becomes patchy, flaking, or visibly worn (typically 15-20 uses). Do not use under direct broiler flame or on stovetop. Store in a cool, dry place away from oils and sharp utensils to prevent premature coating damage.
