In what's known as slack fill, chips manufacturers intentionally inflate the package with nitrogen gas to protect it from damage in transit.

Can chips go stale?

Chips go stale because they've gained too much moisture. That's because chips lose most of the moisture inside them during the frying process, creating a crunchy network of starch molecules. Those molecules are hydrophilic, meaning they attract water from the air around them.

Why do potato chips have a long shelf life?

Snack foods contain preservatives in order to maintain shelf life. Different types of snacks have varying expiration dates: Potato chips will last one month after expiration date. Crackers and pretzels can last up to three months.

How do potato chips stay so fresh in the bag?

Thought that your potato chip bag was puffed up with air? The cushion actually is nitrogen gas. Chip manufacturers fill bags with this preservative gas to help keep chips fresh. If it were filled with regular air, the chips would likely turn soggy and spoil.

What Did We Fry This In? (Taste Test)

Why is Lay's full of air?

The air in chip bags is actually nitrogen, and it's there for a reason. “The reason for the nitrogen and chip ratio is to keep the chips safe during transportation,” Aragon said. “These chips will get handled a lot. So it just ensures the chips aren't getting smashed, and it keeps them fresh longer.”

Do chips go stale in Ziploc bags?

Potato chips and Tostitos were sealed and stored, then tasted after five weeks to see which tasted freshest. And the results? "The chips from the Ziploc and the Glad bags were a bit stale.

Why do chips taste better cold?

There's even a bit of science behind why cold Pringles taste great. Potato chips have basically no water in them, meaning that the molecules most prone to telegraphing a temperature change to your mouth are MIA.

Why do you soak chips in water?

Why do chip bags have so little chips?

Indeed, this “slack fill” is purposefully added to chip bags by snack manufacturers in order to act as a sort of cushion around potato chips and other delicate products. The top half (or two-thirds) of the bag is pumped full of gas before it's sealed.
