How can I be sure the paper marketed as "Phenol Free" does not contain BPA or BPS?

There is no way to visually tell if a particular thermal receipt is Phenol Free -- the only way to verify a receipt's chemical content is by lab testing.

We periodically test our phenol free receipt paper to ensure they are free of BPA, BPS and other Phenols. Please follow the link below for our latest test results. If you have any further question or concerns do not hesitate to reach out to us.
