What product do you use to shrink wrap items onto bottles for promos?

I will use a heat gun, but need to know what kind of film and where to find it. The will be on a 1L spray bottle and the promo item is very light.

At craft shops (the big ones like Micheal’s and Hobby Lobby) you can buy stuff to wrap up gift basket that you shrink.

You might also look at the stuff that you seal up windows with in the winter. You use a hair dryer on that but it isn’t very thick but might still work.

And finally check out Kinko’s. Not sure but they might have something for you.
