      Ah I thought only paper products needed an inner coating like that. Is there a concern of it oxidizing or something?

        Aluminum is poisonous in larger amounts and a lot of can contents are pretty acidic. You could probably line them with non reactive metals like gold, but thst would be very expensive in comparison.
