Reusable Ice Packs Buying Guide
Why use reusable ice packs
Loose ice melts into your bag. A frozen water bottle takes up the space of a drink. Reusable ice packs do the same job without the mess: they freeze solid, keep the food around them cold and go back in the freezer when you get home.
This set gives you four slim packs. Use one in a small lunch box, or two or three in an insulated lunch bag or cooler bag.
Why slim matters
Most ice bricks are 3 to 4 cm thick. These are 1.3 cm. That means they fit in the gap down the side of a lunch box that is already packed, or flat on top of a sandwich container, without pushing the lid open.
Each pack measures 12.1 cm by 12.7 cm, roughly the size of a sandwich.
How many do you need
| Use | Packs |
|---|---|
| Small kids' lunch box | 1 |
| Adult lunch bag for a work day | 2 |
| Insulated lunch bag on a hot day | 2 to 3 |
| Small cooler bag or baby bag | 3 to 4 |
For a large cooler box on a weekend away, bigger ice bricks will hold the cold longer than slim packs.
Getting the most cold out of them
- Freeze overnight. The maker says each pack needs a full night in the freezer.
- Freeze them flat. The filling sets evenly and the pack stays thin.
- Pack them on top and at the sides. Cold air sinks, so a pack on top cools more than one underneath.
- Use an insulated bag. A pack in a thin plastic bag will thaw much faster.
- Start with cold food. Pack straight from the fridge, not from the bench.
The maker does not publish a cold-hold time, and we will not make one up. It depends on the weather, the bag and how many packs you use.
Safety and care
The shells are BPA-free plastic, sealed and listed as leakproof. The maker says they are non-toxic and safe to pack with unwrapped food.
Hand wash only. Rinse them in warm soapy water, pat them dry and put them back in the freezer. Throw one away if the shell cracks.
These are hard packs for keeping food cold. They are not soft therapy packs, so wrap one in a cloth if you use it on skin.
