It’s rated for 100 wavelength. What are the gates wavelength?

Actually, now that I looked into it, pretty much any Faraday bag should work. According to this website, some RF anti-shoplifting towers have frequencies of up to 13.56 MHz. Convert that frequency to a wavelength, and you get... 22.1 meters. Even the shittiest Faraday bag would be able to block that out. So, as long as they're only using RF towers, and as long as you don't leave any gaps when you wrap it up, you should be fine.

Now that I've looked it up, yes, it looks like aluminum foil would indeed work. You just need to make sure that the product is completely wrapped in it - small gaps could let the radio waves leak through, and trigger the alarm.

I don't know. All the Faraday cages I've seen have been actual cages composed of crisscrossing wires. I'm not sure if a solid plane of conductive metal would have the same effect. I'll do some research on this, and let you know what I find.
