Stasher bags and Stojo containers are the silicone lunch box answer

If you want a lunch container that’s food-grade silicone and folds flat when empty, your two main options are Stasher bags and Stojo’s collapsible containers.

Stasher is the gold standard here. They’re made from 100% food-grade platinum silicone, and when empty they lie completely flat — you can slide one into a drawer like an envelope. They work great as sandwich bags, snack bags, or even a bento-style option if you buy a few sizes. The downside is they’re bags, not boxes. If you want something that holds its shape while you eat, look elsewhere.

That “elsewhere” is Stojo. They make collapsible bowls and food containers with lids that squish down flat when not in use. Also food-grade silicone, also fridge/freezer/microwave safe, and they feel more like a proper lunch box — you can eat out of them without wrestling a bag open.

Amazon is full of cheaper generic versions of both. Some are fine, but check the fine print: you want “100% food-grade silicone,” not “silicone-coated” and not a blend. The whole point is avoiding whatever mystery plastic is in the cheap stuff.

Either route beats a drawer full of mismatched Tupperware lids.
