Dry Ice sublimates, meaning It turns to carbon dioxide and the process Is rather slow, which makes It Ideal when boxing.

In terms of normal Ice, try this. Take a 2kg block out of the freezer during the evening and when you awake In the morning, Is It still In that state or In liquid form (melted)? Your package will not be delivered overnight, so my answer Is obvious.

Moreover, 2kg of melted Ice will leave a lot water behind.

It just came to mind as I recently received a musclefood order and it contained ice packs wrapped in plastic to keep the food cold so instead of disregarding them i placed them in the freezer incase i could use them to box with.  They weigh roughly under 3kg and no potential for leaks?

Firstly, the Ice will melt during transit, hence there will be a discrepancy In weight.

Most Importantly and as stated above, the package will be received with bags of water- which Instantly raises suspicion.
