WHAT IS BPA ?
BPA (bisphenol-A) is a chemical that is added to many commercial products, including food containers and hygiene products.
It was first discovered in the 1890s, but chemists in the 1950s realized that it could be mixed with other compounds to produce strong and resilient polycarbonate plastics.
These days, BPA-containing plastics are commonly used in food containers, baby bottles and other things.
BPA is also used to make epoxy resins, which are put on the inner lining of canned food containers to keep the metal from corroding and breaking.
