Its not to insulate it its to stop the air flow through the cooler.
I know its to stop the flow through the cooler, I'm not special :?
My point is that if its covered in metal (tin foil) then that will just heat up too and transfer away some of the heat while gaffa tape wont and cardboard won't because their efficiency at heat transfer is far far less than aluminium, do you follow what i'm saying?
Cardboard will retain the heat and keep it in the cooler, like if you lie on a sheet of corrugated card (like a box) its gets warm where you touch the cardboard pretty fast, this is why tramps use carboard and not tinfoil to keep warm
