Yes. And coated cups like the kind you get for coffee don't use wax anymore (and if they do it's petroleum derived paraffin). They are more likely to use a high-temp polymer

  Paraffin is what most people are thinking of when someone uses the term "wax". I don't think there's an inherent problem there.

  Says you. Doesn't explain why drinking coffee from them triggers a corn allergy, while the exact same coffee from the same store/barrista in a ceramic cup is fine.

    Not sure what you're referring to, but many of the cups use PLA liners which is corn plastic ("plant-based alternative"). So that stuff is not from petroleum. You ought to be able to identify, it's usually labeled on the cup, or the packaging

  Petroleum derived wax isn’t really a problem is it?

  For moisture resistance, paper cups are coated with plastic (typically polyethylene or polylactic acid) or wax (typically parafin).
