What does the #7 represent?
Most plastic containers are marked (usually on the bottom) with a number within a triangle with arrows – commonly known as a recycling symbol. These numbers, known as the resin identification coding system, were created in 1988 to facilitate recycling programs across the country. These recycling numbers can range from #1 to #7, depending on the type of plastic. The #7 recycling label is a catchall indicator for plastics made with a resin other than those in the #1 to #6 designations, or made of more than one resin. The #7 category not only includes polycarbonate, but also includes compostable plastics made of
organic material and other types of plastic that do not necessarily contain BPA (Bisphenol-A). For example, our new Everyday™ line manufactured with Eastman’s Tritan™ copolyester is a #7, but does not include BPA.
