Large contact area: As its flat and thin shape, it has got the largest contact area among all types of ice. The larger its contact area is, the faster it cools other stuff. In comparison with 1 ton of cube ice, 1 ton of flake ice has 1799 sqm of contact area while 1 ton of cube ice only has 1383 sqm, therefore the flake ice has got much better cooling effects than cube ice.
