I was inspired by your pouch to have a go and make one myself. I did mine with alfoil and a laminator pouch. I linked back to you on my project page: http://hacktheevening.wordpress.com/2013/03/09/faraday-pouch/

Have you tried making a Faraday cage out of a woven mesh? If you have seen mythbusters where Adam makes a faraday cage to block a mobile phone signal, demostrates that signals of any strength are blocked. From my memory at school, a faraday cage blocks by allowing the signal that is induced near to or by it is passed around the outside of the cage but not through it. Nice 'ible BTW.

I work in the aircraft industry and have a lot of aluminum skinned/aluminum honeycomb material (basically just plywood for airplanes), and wonder if that would attenuate the lower-end RFID you wrote about having tested. (Been a long time since my Navy electronics training-can't remember all the math bits.) Some of this stuff is like 4mm thick and looks like it would make a great sleeve or flap. Attachment is fairly simple with either screws and nuts or, provided one uses the proper spacers, rivets. I have material that runs all the way up to 2cm thick, some with aluminum skin and some with fiberglass skin. What do you think?

I'm not up on the math you'd need to do to answer this, nor am I clear about which particular frequency you're after. What is the application? Are you looking to use some materials you have for your own pouch?
