Answer:
A packet of chips is vulnerable to getting squished. Squished chips are subpar. You could put the chips in a solid container that resists squishing, but that makes the package bulky and expensive.
Gases provide good protection from breakage and the air is a very common gas.
Remember that a lot of packaging is either bubbles of air (bubble wrap) or or foamy soft shapes.( air trapped in a solid).
The problem with air is that it contains oxygen. Oxygen however, is chemically corrosive, and will cause the chips to spoil quickly.
Nitrogen is a gas in the air so is readily available. Nitrogen does not affect the food, and when released into the air has no affect. (It forms only a tiny % increase of nitrogen to your local air.
