MEX.. I'm not so sure about vacuum panel insluation,, (Standard thermous bottle uses this kind of thing, which is why it's also called a vacuum bottle if you wish to use the proper name).
I recall back about 1970 give or take a few they came up with a "Super Insulation" basically it is layer after layer of aluminum foil and paper sandwitched together...
on the TV they make a cube, put a live birdlet inside, boil it a while and open the cube and let the still happy bird out.
Of course today you can't run a commercial like that.
