"WitrynaPlastic cups are typically thicker than the paper ones too, and a thicker cup makes a better insulator. The paper cup is a lot like the styrofoam cup I mentioned above, with the dry wood fibers trapping air. Usually paper cups are waxed, and wax is a poor conductor of heat (but better than air). It is probly thin and lets heat through. " - Is styrofoam a good insulator of heat
