This method is easy, but it won’t keep the air out unless you store the opening under a heavy item. The more air there is the bag, the faster your chips will become stale.
Press down along the top of the bag after each fold to keep it closed.
Your folds may slowly come undone if you don’t weigh them down at all.
This method creates the best seal but it requires a little more work. You’ll also need more of the bag to be empty, so you may not be able to do this if your bag is mostly full. This method is really hard to pull off if you have a smaller bag of chips. You’re better off simply folding smaller bags over.
Keeping the bag held down shouldn’t be difficult. The easiest way to do it is to use your middle, ring, and pinky fingers to press them into the table while you’re folding.
Press your palm flat into the folded sections of the bag to flatten them.
Essentially, the tension between the corners and the folds at the top will keep the bag sealed.
