Alloy 8011 H24 Aluminum Foil Jumbo Roll (38 microns) is a versatile, high-performance foil designed for converting into packaging, insulation, sealing, and protective barrier products. Combining the widely used AA 8011 alloy with the H24 temper (strain-hardened and partially annealed), this foil offers an ideal balance of strength, formability, puncture resistance, and barrier performance. At 38 µm thickness, it sits in a "workhorse" range-thick enough for demanding converting processes while remaining flexible, lightweight, and cost-efficient at scale.
This product is typically supplied as a jumbo roll to support high-speed laminating, printing, slitting, and rewinding operations. It is engineered to run smoothly on modern converting lines, providing consistent gauge control, strong mechanical properties, and dependable surface quality for coatings, adhesives, and inks.

Features That Matter in Converting and Packaging
| Feature | Customer benefit | Why 38 µm helps |
|---|
| Excellent barrier to light, odor, and oxygen | Protects aroma, freshness, and sensitive contents | Thicker gauge improves barrier robustness and handling |

Typical Applications
AA 8011 H24 foil at 38 microns is commonly used as a barrier and structural layer in both consumer and industrial products.
| Application area | Typical converted product forms | Performance role |
|---|
| Flexible packaging & laminates | Foil-paper laminates, foil-PE/PET laminates, sachet structures | High barrier + stiffness + print/lamination base |
| Lidding & sealing structures | Heat-seal lids (as part of laminate), peelable sealing webs | Dimensional stability and seal integrity (laminate-dependent) |
| Pharmaceutical & medical packaging | Secondary barrier layers in laminated structures | Light/oxygen barrier, protection and shelf-life support |
| Thermal insulation facings | Foil-faced insulation, reflective facers | Reflectivity + vapor barrier + durability |
| Industrial wrapping and protection | Protective wraps, interleaving, specialty covers | Puncture resistance and shielding |
Note: End-use compliance (food contact, pharma) depends on surface condition, lubricants, cleanliness, and applicable certifications. Always align with destination regulations and converter process requirements.
AA 8011 is an Al-Fe-Si series alloy widely selected for foil due to its excellent processability, consistent strength, and good barrier performance. The H24 temper provides a practical mid-point: stronger than fully annealed foil, but still formable enough for downstream operations that require bending, folding, or moderate forming.
| Parameter | AA 8011 | H24 temper relevance |
|---|
| Strength level | Medium | Helps resist web breaks and handling damage |
| Formability | Good | Partially annealed state improves bend behavior |
| Surface quality | High potential | Suitable for converting when properly controlled |
| Typical use | Packaging/insulation foil | Converting-friendly temper for jumbo roll supply |
