Lately we have been getting a lot of questions about traveling by air with ice packs.
Here’s the skinny…
You can bring Cooler Shock packs through security as long as they are frozen, no issues. (You can get details at TSA.Gov)
If the packs are defrosted they will not let you take them on the plane. Consider checking ahead at your hotel or other destination to be sure you can re-freeze the packs to take them home.
Of course you can transport the dry packs if they have not been hydrated yet. The CS packs should stay frozen all day if you take them to the airport in a cooler.
We’ve had a lot of questions related to this and the transportation of breast milk. It seems that we’ve been mentioned somewhere on a website regarding the great success one Mom had using CS for this purpose. If you have specific need please check our chart for usage on our main web page or contact us for specific details.
Cooler Shock ice packs absorb heat from both sides. Understanding that, consider allowing both sides to work for you for best performance. If you place the pack directly on the bottom or in direct flush contact with the sides of a cooler, you are using the ice pack to absorb heat through the cooler wall and then from the outside. Said another way, you are cooling the wall of the cooler and the outside. For many on a one day trip this is probably irrelevant. For those that want the most out of the pack, place it so that it is not in direct contact with the floor or sides of the cooler. You can do this by placing beverages under it or use basic bubble wrap to create an airspace.
For those taking multiple packs for multi-day use, stack the packs (still using something to keep the bottom pack off the floor of the cooler (bubble wrap again). As the upper packs give off their energy, remove them and expose the next pack. By doing this you are using the upper packs as insulators for the lower packs thereby not allowing them to all cool at once.
Conversely, when freezing your packs, create air space in between them when placing them in the freezer to get the highest energy absorption in the shortest amount of time. One way is to spread them out on different shelves.
Yes, there is a science to this and you will have a much better experience when armed with knowledge.
