Pressure sensitive tape...WTF?

I'm getting ready to ship my 360 off to a repair center (got it launch day and it finally decided to give me the three red lights for no reason) and the wonderfully vague packing directions don't tell me jack squat about the "pressure sensitive" tape. It just won't stick. I feel like the dumbest person ever for having to ask this, but I've tried everything. How in god's name do you get that stuff to seal the package?

Any and all help will be greatly appreciated.

Did you peel the back off of it??EnderSR388

You know, I've been trying too for the past five minutes but since I couldn't I figured that wasn't how it worked (there's no tab or anything) and then of course I go back to try and get it off the first time.
