How do potato chips stay fresh and crisp in the plastic bags they are housed in ?

Solution

Potato chips stay fresh and crisp in the plastic bags they are housed in because chip bags are filled with Nitrogen ( $N_{2}$ ) gas.
When Nitrogen is introduced into a package, it drives out Oxygen and any moisture present and prevents the oxidation of oils present in the chips.
This keeps the chips fresh and crisp in plastic bags.
Nitrogen gas is often filled in chips packets to prevent rancidity as it is not too reactive (inert) with either oils or fats of chips.
