You don't unwrap it at all until its already exposed and you're ready to develop. You take off the tape, as you did, to release the paper leader and then use that to load your camera. I'm not sure what camera you are using so I can't really say how exactly to load it. But once you have the leader fed into the taking spool in your camera you advance the roll until you see 'Start' with an arrow that lines up with a certion position in your camera...usually indicated by a red dot or arrowhead. Then you close the camera up and and advance until you get to the (1) frame, and you're ready to shoot. Sorry to be so vague, but I don't know your particular camera model....thats the jist of it though.
