Is Parchment Paper Non Toxic? | What Changed in 2024

If you’ve wondered whether that roll of parchment paper in your drawer is leaching chemicals into your food, the honest answer is: it depends on which roll you bought and when. That regulatory change made the default U.S. market supply significantly safer than it was just a few years ago. But not all parchment paper is created equal, and a few simple label checks separate the safe rolls from the ones you should toss.

What Makes Parchment Paper Non-Toxic or Toxic?

The safety of parchment paper comes down to two things: the coating and the bleaching process. Food-grade silicone (polydimethylsiloxane, or PMDS) is FDA-approved as non-toxic and stable up to 420–450°F. The problem arises when manufacturers substitute silicone with older coatings like Quilon (which contains chromium) or PFAS-based grease-proofers. Bleached paper adds another risk, potentially releasing trace dioxins at high heat.

How the 2024 PFAS Ban Changed the Game

The catch is that old stock may still exist on shelves, so checking the label for “PFAS-free” remains important, especially with private-label or store brands.

How to Choose Safe Parchment Paper in Three Steps

You don’t need a chemistry degree to pick a safe roll. Here is the sequence that works:

1. Pick unbleached brown paper. The natural brown color means no chlorine bleaching was used, which eliminates the dioxin risk. White parchment is almost always bleached.
2. Confirm silicone coating. Look for “silicone-coated” or “food-grade silicone” on the box. Avoid any label that mentions “Quilon” or doesn’t specify the coating type.
3. Check for PFAS-free and compostable certifications. A “Certified Compostable” label (like BPI or TÜV OK Compost) limits organic fluorine to 100 ppm or less, which is a reliable proxy for PFAS-free status. If the box says “PFAS-free” explicitly, that is even better.

One common mistake is assuming all parchment paper is the same. Some older private-label brands and international imports may still use Quilon or PFAS coatings, which are not safe for food contact. When in doubt, buy a brand that states “unbleached, silicone-coated, PFAS-free” on the package.

When To Stop Using a Roll

Even safe parchment paper has limits. Do not use it above 450°F, under a broiler, or over an open flame — silicone breaks down and can release compounds at extreme heat. Silicone-coated parchment is generally not reusable; the coating can degrade after one use and potentially leach if used again. Uncoated parchment (the sulfuric-acid-treated kind) is reusable but increasingly rare in stores. And despite the marketing, silicone-coated parchment is not fully compostable due to the synthetic polymer coating.
