Legal Battle Erupts Over Whose Plastic Consumers Should Trust

In 2007, Eastman Chemical began marketing a tough new BPA-free plastic called Tritan. Business was good, says Lucian Boldea, a vice president at Eastman.

"We were able to make the statement that our product is not made with BPA and would release data to consumers to support that fact," he says.

BPA, short for bisphenol A, is a chemical that can act like the hormone estrogen. While environmental groups and the government still disagree about whether BPA or any estrogen-like chemicals pose a health risk, consumers are clear that they want Sippy cups and water bottles made of plastics they consider safe.
