Why are chip bags always HALF-EMPTY?
Often when we open a bag of chips or other snacks, it seems like there's more air in it. The first thing most people think is that it's a manufacturer's scam.
TL;DR
- The seemingly empty space in snack bags is for protection during transport, not a scam.
- This space prevents chips from being crushed when bags are stacked.
- Bags are filled with nitrogen, not air, to preserve freshness.
- Nitrogen keeps chips crispy and prevents spoilage from oxygen and moisture.
- Nitrogen is a safe gas, making up 78% of the air we inhale.
