"BPA-free" refers to products that do not contain bisphenol A, a chemical commonly used in the production of certain plastics and resins. BPA is often found in items like water bottles, food containers, and baby bottles. Concerns have been raised about its potential health effects, particularly regarding hormone disruption. Manufacturers label their products as BPA-free to assure consumers that these items do not contain this chemical. This label is especially important for products intended for children or for food storage, as many people prefer safer alternatives to reduce health risks associated with BPA.
