Do receipts and some food-contact paper products contain bisphenols?
Use caution with thermal receipts and food-contact paper. A 2026 Frontiers in Public Health study found BPA, BPS, and other bisphenols in paper products, with thermal receipts carrying much higher levels than other paper items.
What is actually in it
Paper products are not all the same. Thermal receipts and tickets can use BPA, BPS, or other bisphenols as color developers. Some food-contact paper can also carry chemical residues from coatings, recycled paper, or processing.
A dry napkin is not the same as a greasy food wrapper. Receipts touch skin. Food wrappers touch food. Hot or oily food can make food-contact materials more important.
What the research says
A 2026 Frontiers in Public Health study tested 120 thermal receipts and 32 other paper products from Korea. Thermal receipts had total bisphenol levels 100 to 10,000x higher than other paper products. The study also found higher estimated exposure for workers who handle receipts often.
This does not mean every paper product is a major risk. It does mean receipt handling and food-contact paper are worth simple swaps.
What to do at home
Skip printed receipts when you do not need them. Wash hands after handling thermal paper. Do not store receipts with snacks, bottles, or baby items.
For food, move hot or greasy takeout into glass, ceramic, or stainless steel when you can. Use glass storage at home instead of leaving leftovers in coated paper wrappers.
