OK to insulate windows with regular plastic sheeting?

Will black plastic sheeting insulate my windows as well as the commercial shrink-wrap stuff? I've used window insulator kits like this
and they work great. I was wondering if I could skimp. First, would any plastic do as well? I already use this stuff
to block light while I sleep. If that's not as good, is there something special about shrinking the commercial kit plastic with a hair dryer, or is that just for looks? I'd rather not borrow one every year.
