I like the tube material (sealed on two sides) available from ACP or CST. They also sell clips to close the ends with. I first bought a 36" wide tube but switched to the 18". I almost always get a very good seal and it is faily easy to get the wing into the bag and then seal the ends with the clip. I think ACP sells it for 4.25 for 3 yards, fairly cheap and I can reuse it numerous times.

What to use for vacuuming wings?
I use 1.0 mil clear Lawn and Leaf Bags. To seal, I use a c-channel clamp from a window insulation kit. Since it's a bag, it only needs to be sealed on one side.
The disadvantage to the thin material is that it'll develop leaks after a couple of uses. The advantage is that it conforms to corners very easily and is less likely to crush balsa at the overhangs.
I've heard of people using 2-3 mil drop cloths if you like thicker.
If you don't mind spending the money, I'm sure the polyethelene tubing sold by ACP and CST and other plastic suppliers is probably the way to go. If you're cheap like me, you'll keep your eyes open for big clear garbage bags. Just make sure you get something big enough for your wings. Drum liners seem to be the biggest at 55 gals or so, but I haven't seen them at my Home Depot in clear.
You'll also have to figure out some way to attach the vacuum tube to the bag. Again, there's equipment from CST and ACP, or you can make it yourself. The critical consideration is how to keep the bag from collapsing on the vacuum tube and that you can spread the vacuum throughout the bag. Some methods which you can try are as simple as poking a hole in the bag, inserting the tube, placing a paper towel below the opening of the tube, and sealing the poked hole/tube junction with rubber cement.
Good luck with your bagging.
