Best Lunch Boxes for Elementary School Kids (2026): The One We Chose

School lunches in our house are an assembly line. Most nights after dinner the counter fills up with boxes, cut fruit, crackers and whatever the week’s favorite is, and the boxes go in the fridge so the morning is just grab-and-go. We went through a lot of containers before we settled on one. Some had lids too stiff for a first grader to open, which meant lunch came home untouched. Others let the applesauce creep into the sandwich, which meant lunch came home untouched for a different reason.

We chose the Bentgo Kids because it fixed both of those. The single latch on the front is easy for small hands, and a silicone seal under the lid presses down on each of the five compartments, so a scoop of yogurt or a few wet berries stay where we put them. The compartments are sized for kid portions, which makes packing faster — one main, one fruit, one veggie, one snack, one little treat — and the tray pops out for the dishwasher. It is not meant for soup, so on hot-lunch days we pair it with the small Thermos food jar on this list.

Several of the others here earned a real look. The OmieBox is the one we would choose for a kid who wants a warm lunch every day, the PlanetBox is the stainless box that will outlast elementary school, and the Bentgo lunch bag keeps everything cold until noon. The Bentgo Kids won because it was the box our kids could actually open on their own — and it came home empty.

To finish off the backpack, our guide to kids’ water bottles that don’t leak has the bottle that rides next to it, and our food storage containers guide covers the containers we prep lunches from all week.
