Multi-Client-Project "BPS, BPA, Pergafast 201 and PFASs"
Due to the ban of Bisphenol A (BPA) the developers used for thermal papers changed from BPA to alternatives.
Among these alternatives Bisphenol S (BPS) and Pergafast 201 have been shown to be the main substitutes. Although thermal papers are considered as unwanted material in recovered paper standard grades, these papers are still present in the recycled paper loop. Amendment of a migration limit for BPS in BfR recommendation XXXVI for food contact materials (fcm) made of recovered paper were announced. Restrictions for further thermal developers can be expected.
