The moisture in the air cools around the ice pack. Then it freezes to the ice pack.
Research "latent heat" and "heat of fusion" on the web for more info.

When the ice pack is taken out, the moisture in the open air condenses on the surface of the ice pack.
My 2 points. And if you help it could be my 12 points.

The moisture in the air comes into contact with the cold bag, this condenses and then freezes the liquid in the air. Hence frost.

your ice pack cools the air around it and the cooling allows the tiny amounts of water floating in the air to condense and they form a frost

In the freezer the air around it is the same temperature as the ice pack.
When you take it out it starts to cool the warmer air around it. Some of the water vapour in the air sticks to the ice pack and is frozen.

Condensation will appear on the outside, but it is still at a freezing temp...thus the frost
