Bisphenol A (BPA) is used for thermal paper developer because of its stability and heat-resistance. During use of the thermal paper, BPA can get in contact with the skin and during recycling BPA can get into the cycle of paper production and cause contamination of other types of paper products. BPA is considered to be an endocrine disruptor and to cause heart disease, type II diabetes, breast cancer, prostate cancer, infertility, and neurological development disorders.
