actually, i thought there was some issue with the membrane boxes in terms of 
the plastic keeping any moisture locked up against the surface when you 
store slices in them? I know i have purchased some slices that went into 
membrane boxes and later showed rust where half individuals from the same 
source didnt show any rust when stored simply on a shelf. i know this is 
hardly a scientific comparison though, but FWIW.... i wonder if the plastic 
in a membrane box could somehow be impregnated with that VCI stuff....
