The best ice packs for kids lunches are (in my opinion) the Medela ice packs that come with a breast pump. They are the perfect size — not too thick or heavy. I have two of them, but one – after significant abuse – has started to leak.
I also have one those plastic soft-sided ice packs
that I don’t remember buying, which means someone once left it here and after enough time it just sort of became ours.
That one definitely leaks. I put it in a large zip-lock bag, but that can be opened by the kids and the bag isn’t really that sturdy. I don’t want the gel pack contents to get near their food.
Then I had an epiphany and decided to try the Food Saver to seal them up.
There’s a little excess vacuum-sealed bag around the edges, but it folds right over and tucks easily in the lunch box. So far, it’s working like a champ!
Do you guys have leaky ice packs as well? What do you use in your kids’ lunch boxes?
