The Issue

Bisphenol A (BPA) is an industrial chemical used to make a hard, clear plastic known as polycarbonate. Polycarbonate is used in a limited number of household containers, including baby bottles, sippy cups, re-useable water bottles (sports bottles), pitchers, water carboys, tableware and food storage containers.

The SPI code is a three-sided triangular arrow with a number one (1) through seven (7) in the centre and letters underneath. Each number identifies the plastic from which the bottle or container is made. The SPI coding system is voluntary; not all plastic products carry a code.

Plastics identified by codes 1 through 6 do not use BPA in their manufacturing process.

Code (7) is used to identify ‘Other Plastics’. Polycarbonate is a code seven (7) plastic; however, the majority of code seven (7) plastics are not polycarbonate.

To determine if a baby bottle is made of polycarbonate, look for the SPI code on the bottom. If you see a code seven (7), the bottle may be polycarbonate. Keep in mind, however, that code seven (7) is also used for other plastics. To be absolutely certain, check to see if the plastic is identified by its name or acronym (PC for polycarbonate) somewhere on the product or package, or contact the manufacturer.

Studies show that the amount of BPA released into the contents of baby bottles is very low when the fluid is at room/serving temperature. The release of bisphenol A into the fluid increases when very hot/boiling fluid is added to polycarbonate bottles.
