Nitrogen is heavier than oxygen, so they fill the bag with nitrogen that moves all the oxygen in the bag. Oxygen cause chips to become more and / or possibly rancid if it gives them a shelf life, because nitrogen is inert and does not react with food. Nitrogen is used in this way in the production of many foods / drinks - it is also blown into bottles of wine after filling for the same reason.
