Plastic 7 marked PC — polycarbonate
What it looks like
A triangle with 7 inside and PC printed below, often on a hard, glass-clear or amber-tinted item.
What it means
Old five-gallon water-cooler bottles, some reusable sports bottles, safety glasses, DVDs and machine guards. Its strength and clarity are why it was used for durable food containers, and its BPA content is why it largely was replaced in that role: BPA migrates from polycarbonate into food, faster when the container is hot, scratched, or washed with strong alkaline detergent. The FDA banned BPA-based polycarbonate in baby bottles and sippy cups in 2012 and in infant formula packaging in 2013. A hard clear plastic bottle old enough to be polycarbonate is one to retire rather than to keep refilling.
Defined by ASTM D7611. Where a symbol differs between standards, the difference is described above rather than resolved — both versions are in circulation on real labels.
