But the point is to keep it in the mainstream mail and never have your package go into "further processing" i.e. x-rays. I do know that carbon does remove smells. They use it in HEPA air filters and vodka processing to absorb all the nasty flavors, colors, and smells. Hell, its even used in clandestine drug manufacture, from what I've read. This is different than a few sheets of newspaper - activated carbon (aka norit) will adsorb almost anything on a molecular scale.The point is that if you have this stuff in between layers than there are drastically less molecules available to permeate the outer membrane.Well, I haven't done much research into the properties of activated carbon, but if it does what you say it does, then I would recommend putting it on the innermost layer of your vacuum HDPP packing, since I think the drug sniffer electronic equipment will have activated carbon amongst the things that it searches for. I mean, if you were operating such a machine, that's what you'd do yourself, right?
