Heard that article on the radio. The host did point out that packaging is supposed to keep the food clean, so having edible packaging kinda defeats the purpose of germ-free eating.
Anyway, I'm not sure this wrap would be good for bondage. I mean, if it is edible, it's either going to melt down via saliva or get bitten through. It does sound like a fun thing to play with, especially if the mummy is gagged beforehand.
