Have you ever grabbed a bag of chips, only to feel like it’s more air than snack? Before you dismiss it as a sneaky marketing trick, consider this: that extra puffiness is actually there for a reason. Many products, especially fragile ones like chips, are intentionally packaged with added air to protect them during transport. But not all foods benefit from bloated packaging—some require the opposite approach. Let’s explore why and how air plays a role in preserving your favorite snacks and perishables.
Why Chips Need Extra Air
That inflated chip bag isn’t trying to fool you—it’s safeguarding your snacking experience! Here's how:
Protection Against Crushing :
- Chips are delicate and prone to breaking. Nitrogen gas (not oxygen) is often pumped into bags to create a cushioned environment, preventing damage during shipping and storage.
Maintaining Freshness :
- Nitrogen displaces oxygen, which slows down oxidation and rancidity, helping the chips stay fresher for longer.
Perception of Value :
- A well-puffed bag gives the impression of fullness, even though the actual volume of chips remains consistent.
