Vented Glass Bottle The new BornFree glass bottle is made of pure natural glass and is today"s safe non-controversial material. Glass is free of Bisphenol-A (BPA). This chemical compound is used to create polycarbonate plastic, a hard, clear plastic used widely in consumer products, including food and beverage containers. A growing body of scientific research suggests that small amounts of BPA may leach into foods or beverages stored in polycarbonate containers, especially when the contents are acidic, high in fat, or heated. Research suggests that BPA may act as an endocrine disruptor, a substance which mimics natural human hormones. BornFree glass bottle. Your safe, more natural alternative.
