Solution
In order to prevent the spoilage of potato chips, they are packed in plastic bags in an atmosphere of N2.
Explanation:
Nitrogen (N2) is an inert gas that creates an oxygen-free environment inside the bag, preventing the aerial oxidation of fats and oils in the chips. This stops them from turning rancid and keeps them crisp and fresh for a long time.
