Use a bag clip
We always open a package of chips and don’t eat the whole package at once. After some time has passed, when we want to eat our favorite snack again, we realize that the chips have lost their crunch and become soft.
To solve this problem, buy bag clips before you travel and attach the clips once you’re done eating to keep your snacks fresh for a long time.
Plus, these clips aren’t just a road trip hack — you can use them to store snacks at home, too.
