BPS-free refers to products that do not contain Bisphenol S (BPS), a chemical commonly used as a substitute for Bisphenol A (BPA) in manufacturing plastics. BPS is often found in products like polycarbonate plastics and epoxy resins, which are used in containers that store food and beverages. Due to growing concerns about the safety of BPA, manufacturers have shifted towards using BPS, claiming it to be a safer alternative.
