Q: CONTEXT: Probably not. Cans are generally marked at point of filling, not at point of manufacturingThe plastic liner looks plastic'y in all cases, it's very hard to tell. Epoxy is harder than other plastics, but there are epoxies that are BPA free anywayAluminium cans are more likely have a epoxy liner that will give off a trace of BPAMany steel cans do not use epoxy or other BPA plasticsHaving said that the tested BPA release from a can is 100's of times lower than the recommended maximum daily dose. So in theory there is nothing to really worry aboutThe common sense answer is, if epoxy dissolved into the cans contents they wouldn't use it would they. The whole reason it's there is to stop the contents 'eating' the can  <sep>  Q: Is there a definitive way to know if a tin can is lined with BPA? A: Probably not. Cans are generally marked at point of filling, not at point of manufacturing  Q: Is there something obvious from the appearance of the inside of the can?
