hi there, please don't double post. I know nobody answered your last post, but maybe that's because no one knows the solution.
i can help you only a little bit, but that's just the basics.
first you'll have to make a dragger, and name it. then you'll have to use the current y-position to determine how much the package needs to be unzipped.
i have no idea how you have to make the package to peel off.
you might wonna try google for it, i really have no idea. i'm not very good in working with movieclips and timelines, i program mostly in actionscript
Greetz and good luck,
