Dry ice
Does anything need to be placed under dry ice in a cooler to protect the cooler?

Dry ice (~ -100 F at atmospheric pressure) is cold enough to make some plastics brittle, maybe even crack them by thermal contraction. That being said, when we use it theatrically it is delivered in a bin lined with some kind of plastic, and we transfer the stuff to plastic beverage coolers to carry it to the fog machines. Have not cracked one yet, 20 years playing with the stuff.
But I wouldn't use it as an ice substitute or supplement for a cooler. It turns a cooler into a freezer, kind of cold for ice cream (will be rock hard) and can freeze-burn meats and more fragile veggies.
