Preserve products are made with recycled polypropylene (#5) plastic, which does not require BPA to achieve its necessary material properties. BPA is typically found in #3 and some #7 plastics. Additionally, Preserve products have been tested for leaching by independent labs. These tests have consistently shown that our plastic meets leaching requirements more rigorous than the standards set for tap water. These tests have also shown that Preserve products are BPA free.
