Is it safe to use treated paper products for hot or greasy food contact?
caution
Short answer
Paper is not automatically safer than plastic. Coated or treated paper can contain bisphenol analogues, PFAS, or other food-contact chemicals.
For hot, greasy, or repeated food contact, use porcelain, glass, or stainless steel when practical.
Why this matters
Food wrappers, paper bowls, paper cups, takeout containers, and receipts can look simple from the outside. The coating or treatment is the part you cannot see.
Heat and grease matter because they can increase transfer from food-contact materials.
What the research says
A 2026 Frontiers in Public Health study found bisphenol analogues in paper products from Korea. Thermal receipts had much higher total bisphenol concentrations than other paper products.
A 2026 Science of the Total Environment study found PFAS in food-contact paper products. A 2026 Journal of Hazardous Materials study identified 114 migrating compounds from paper, plastic, and multilayer food-contact materials during lab testing.
What to do instead
Do not use treated paper as your daily hot-food surface. Move hot or greasy food to porcelain, glass, or stainless steel when practical.
Wash hands after handling thermal receipts, especially before eating or feeding a child.

What to use instead
For hot or greasy food, porcelain plates and bowls are a better repeat-use surface than treated paper.
