But what if it's not in the rack but on the top of it?

But what if it's not in the rack but on the top of it?

The normally expected spatial relationship between an envelope and a rack is like this:

In this case we say that it is in the rack. The envelope could be in any other spatial relationship with the rack. It could be lying on top of the rack, under the rack, next to the rack, or anything else you want. In your examples, "on" and "on top of" suggest that the envelope is in contact with the upper surface of the rack. "above" suggests that it is separated from the rack, e.g. on a shelf or ledge that is above the rack.
