While some parchment papers contain no added PFAS, others have tested positive for fluorine (a marker for PFAS). Because manufacturers are not required to disclose proprietary coatings, PFAS can still be found in some brands. Most standard parchment papers are coated with silicone to achieve their non-stick properties, not PFAS.
Parchment paper can pose toxicity concerns depending on how it is manufactured and the coatings applied to it. The primary risks stem from three specific factors:
King Arthur Unbleached Parchment Paper is designed to be PFAS-free. Instead of relying on PFAS, it uses a high-quality silicone coating that is considered safe for standard baking applications.
Some third-party consumer watchdog groups and laboratory tests have detected trace levels of fluorine (a marker for PFAS) in Reynolds Kitchens parchment paper. However, the manufacturer states that these products are not intentionally made or treated with PFAS, PFOA, or PTFE.
The healthiest parchment papers are unbleached, totally chlorine-free (TCF), and free of PFAS "forever chemicals". Health and consumer safety experts recommend looking for uncoated paper or silicone-coated parchment, as silicone is a safe, non-toxic polymer that prevents chemicals from leaching into your food.
To find PFAS-free parchment paper, look for unbleached, chlorine-free, and certified compostable brands. Independent testing identifies these top, non-toxic options that contain no intentionally added PFAS:
Although parchment never stopped being used (primarily for governmental documents and diplomas) it had ceased to be a primary choice for artists' supports by the end of the 15th century Renaissance. This was partly due to its expense and partly due to its unusual working properties.
Consumer studies and independent laboratory testing have found that Ziploc brand bags do not contain detectable levels of PFAS ("forever chemicals").
While there is no immediate medical treatment or magic pill to "flush" PFAS out overnight, your body eliminates them naturally over time through bodily functions like urination, sweating, and blood loss (such as menstruation).
Parchment paper can pose health, safety, and environmental issues, primarily because of how it is manufactured and used.
Yes, parchment paper is generally considered safer and healthier than aluminum foil. While foil can leach small amounts of aluminum into food—especially at high temperatures or with acidic ingredients like tomatoes and citrus—parchment paper is non-reactive and does not leach chemicals.
Third-party tests indicate that Kirkland Signature Culinary Parchment paper contains detectable, though low, levels of fluorine, pointing to the possible presence of trace or incidental PFAS. While these trace levels likely mean PFAS were not intentionally added, it is generally not recommended by some clean-living advocates.
4 Best Parchment Papers, Tested by Our Experts
To avoid toxic chemicals like PFAS, chlorine bleach, and heavy metals, switch to certified non-toxic, unbleached parchment paper. These alternatives use natural silicone (derived from sand) for non-stick properties and are totally chlorine-free.
Parchment paper, with its food-safe silicone coating, poses minimal risk compared to other non-stick options. Consumers seeking to avoid exposure to potentially harmful chemicals can rest assured that parchment paper is a safer choice for baking and cooking.
Unbleached parchment paper is generally considered the healthier and more environmentally conscious choice. While both papers are perfectly safe to use, unbleached paper avoids the chlorine-based bleaching process and potential chemical residues.
Does Chick-fil-A's packaging contain PFAS? Products with oil and grease resistant coatings containing PFAS were fully phased out chainwide in the summer of 2022.
PFAS are generally considered more dangerous than microplastics. While both are widespread "forever pollutants," PFAS are toxic at extremely low levels and are definitively linked to severe, confirmed health issues. Microplastics are physically invasive, but their direct health effects on humans are still being studied.
Several popular bottled water brands consistently test at non-detectable levels for "forever chemicals" (PFAS). Reputable studies and water quality testing have identified the following brands as PFAS-free:
Conventional plastic cling films typically do not contain intentionally added PFAS, as they are largely made of polyethylene (PE) or polyvinyl chloride (PVC). However, they are known to contain other concerning chemicals like plasticizers (such as DEHA or phthalates) that can leach into food.
10 Zero-waste plastic bag alternatives
Seafood, particularly shellfish (clams, crab, oysters) and freshwater fish, consistently tests highest for PFAS. This is closely followed by animal-derived products, processed foods, and items in grease-resistant packaging.
Parchment paper can pose health, safety, and environmental issues, primarily because of how it is manufactured and used.
In occult and witchcraft traditions, parchment has long been revered as a sacred surface for transcribing intentions, spells, and affirmations. Its natural qualities are believed to amplify spiritual work, making it a foundational tool for rituals, spell jars, and talismans.
Yes, parchment paper is generally considered less toxic than aluminum foil. Because it is made from processed cellulose, it is chemically inert and doesn't leach metals or chemicals into your meals.
