Packaging Barrier Properties Explained
Barrier properties describe how packaging slows oxygen, moisture, aroma, light, grease, or other risks that can damage a product.
Packaging barrier properties should be matched to the product risk: oxygen for oxidation, WVTR for moisture movement, aroma barrier for flavor retention, light barrier for sensitive ingredients, and toughness for physical handling.
TL;DR
- OTR measures oxygen transmission risk.
- WVTR measures water vapor movement.
- Barrier targets should connect to shelf-life testing.
Decision table
| Property | What it controls | Common product risk |
|---|---|---|
| OTR | Oxygen transfer | Oxidation and aroma loss |
| WVTR | Moisture transfer | Texture loss or clumping |
| Light barrier | Light exposure | Color or flavor change |
| Grease resistance | Oil migration | Staining and pack failure |
