Nitrogen is used in chip bags to displace oxygen, which helps prevent oxidation and slows down the degradation process of the chips. Oxygen can react with the fats in the chips, causing them to become rancid and stale. By filling the bags with nitrogen, the oxygen content is reduced, extending the shelf life of the chips and maintaining their freshness. This process is known as nitrogen flushing and is a common technique used in the food packaging industry.
