I emailed Amy's Kitchen recently to ask what's in the lining of their soup cans. (I saw that they recently started labeling them as 'BPA free,' but I was concerned about BPS, etc.) Here's what they replied with:
"The inside of our cans are lined with a double-coated acrylic and polyester protective barrier made without BPA, BPS, BPF, BADGE or NOGE. It complies with the FDA requirements for direct food contact under the Code of Federal Regulations. You'll be glad to know that as of March 2012, all of our canned foods have this non-BPA lining."
I don't know enough to judge whether there's anything still worrisome in a "double-coated acrylic and polyester protective barrier" - but they didn't substitute BPA with BPS, at least.
