8011 vs 8079 Aluminum Foil — Which Grade Should You Choose?
Quick answer: choose 8011-O for general lamination, food packaging and seal liners where cost matters; choose 8079-O when you need higher tensile strength, lower pinholes and better barrier for retort pouches, coffee or pharmaceutical packaging.
Key differences
| Item | 8011-O | 8079-O |
|---|---|---|
| Alloy | 8011 (Al-Fe-Si) | 8079 (Al-Fe-Si, optimized ratio) |
| Tensile strength | 55–95 MPa | 65–105 MPa |
| Thickness | 6–50 μm | 6–50 μm |
| Barrier / pinholes | Standard | Enhanced (fewer pinholes) |
| Typical use | Lamination, food packaging, seal liners | Retort pouches, coffee, pharma |
How to decide
- Convenience / cost first → 8011-O. The industry workhorse, compatible with PE/PET/CPP lamination.
- Barrier / aroma retention / retort → 8079-O. Denser structure, better moisture & oxygen barrier.
