How can BPA be replaced in the lids of glass jars?

One technique that has already been tried and tested involves gluing a PVC film to the epoxy resin so as to isolate it from the food product.

While this option significantly reduces migration of BPA into the food, it does not eliminate BPA from the food container entirely.

This problem ties in with the challenge of replacing epoxy resin in food tins (see the question "How can BPA be replaced in food tins and drinks cans? ").
