In an article published on July 13, 2015 by the news provider Food Production Daily (FPD), journalist Rachel Arthur reports on aluminum cans as an alternative packaging option for spring water. The UK based company Rexam offers a 100% recyclable, re-sealable aluminum container called Cap Can. Brands such as Noah’s Spring Water from California, U.S., are using Cap Can as an alternative to plastic bottles. Canned water gives municipalities and educational campuses that have banned plastic bottles another option, Arthur writes. According to Rexam, water in cans is a growing trend. Cans have many advantages over plastic such as keeping the content cold for longer and protecting it from UV damage, the company adds.
Aluminum cans are commonly coated with epoxy resins that contain the chemical bisphenol A (BPA, CAS 80-05-7). BPA is a known endocrine disruptor and can migrate from the packaging into the contents. In January 2015, France banned the use of BPA in all materials intended for contact with food (FPF reported). In May 2015 the State of California, U.S., added BPA to the list of chemicals known to cause reproductive harm under Proposition 65 (FPF reported). The development of safe alternatives to BPA-based can coatings with similar technical properties is currently a major challenge (FPF reported).
