Frequently asked questions
What are the best ice packs for lunch boxes?
The best lunch-box ice packs are slim and small so they fit without crowding food, and they freeze fast so one is always ready. Thin gel packs that lie flat cool food evenly and work in lunch bags, bento boxes, and kids' lunches.
How long do lunch box ice packs stay cold?
A frozen slim pack keeps a lunch cold through a typical morning until lunchtime. For longer trips or hot days, use two thin packs, one above and one below the food.
Are small ice packs TSA-approved for carry-on?
Frozen gel ice packs are generally allowed in carry-on if they are completely solid when you go through screening. If a pack is slushy or partly melted, it is treated as a liquid and must follow the 3.4 oz rule. Rules can change, so check current TSA guidance before you fly.
How fast do Kona lunch ice packs freeze?
