Chip packets often seem to contain air but in reality, it’s mostly nitrogen. This nitrogen serves several important purposes in keeping the chips intact and fresh. Here’s a breakdown:

Not Air: The gas inside the packet is primarily nitrogen, not regular atmospheric air. Oxygen in the air would cause the chips to go stale, so nitrogen is used instead.

Maintains Freshness: Nitrogen helps keep chips crisp by preventing moisture from seeping in and causing them to lose their crunch. It also stops oxidation, which could make the chips spoil.

Packaging Protection: The nitrogen cushion safeguards the chips during shipping and handling. Without it, the chips would likely arrive crushed into crumbs.

So, the air isn’t just for show — it is essential for keeping your chips fresh and whole!
