BPA: EPA hasn’t identified a safer alternative for thermal paper
Some researchers and public interest groups have been arguing that BPAfree thermal receipts paper is a preferable alternative, at least from a health perspective. But is it really? That’s what Environmental Protection Agency scientists want to know. And to date, they maintain, the jury’s still out.
