Introduction: The Industry Standard for Soft-Temper Packaging Foil
In the global packaging, food processing, and pharmaceutical industries, material consistency and formability are non-negotiable. Aluminum foil 8011 O has established itself as one of the most widely specified soft-temper foils in international manufacturing, prized for its exceptional ductility, clean surface finish, and reliable barrier performance.
The designation “8011” identifies the aluminum alloy, while the “O” temper denotes a fully annealed (soft) condition — the most pliable state achievable for this alloy. This combination delivers a foil that folds, wraps, and laminates without cracking, making it the preferred choice for converters and packaging manufacturers worldwide.
At Vietnam North Metal, we manufacture and globally distribute high-quality 8011 O aluminum foil in a comprehensive range of thicknesses and widths, supporting customers across the food, pharmaceutical, and flexible packaging sectors.
Understanding the 8011 Alloy and O Temper
1.The 8011 Alloy System
Alloy 8011 belongs to the 8000 series (Aluminum-Iron-Silicon alloys). The controlled addition of Iron (Fe) and Silicon (Si) provides an optimal balance of mechanical strength, rolling performance, and surface quality. Compared with 1000-series pure aluminum foils, 8011 offers superior mechanical properties and a more uniform grain structure, which translates into fewer pinholes and better wettability for laminating and coating.
2. What the “O” Temper Means
The O temper refers to the fully annealed condition, achieved by heating the cold-rolled foil to recrystallization temperature and holding it to remove all work hardening. The result is:
- The softest, most ductile state of the alloy
- Maximum elongation for deep folding and wrapping
- Excellent dead-fold characteristics (the foil stays folded)
- Minimal risk of cracking during high-speed converting
This makes 8011 O the ideal specification for applications where the foil must conform tightly to product shapes or be laminated to films and paper.
Chemical Composition
The performance of aluminum foil 8011 O is governed by its precise chemical balance.

Mechanical and Physical Properties
In the O temper, 8011 aluminum foil exhibits low tensile strength but very high elongation — precisely the characteristics required for soft packaging.

Standard Specifications
Vietnam North Metal supplies aluminum foil 8011 O across a broad specification range to suit diverse converting requirements.
Custom thicknesses, widths, and coil weights are available upon request.
Key Performance Advantages
1.Outstanding Formability and Dead-Fold
The fully annealed O temper delivers maximum ductility, allowing the foil to wrap tightly around irregular shapes and retain its folded position — essential for confectionery, dairy, and food wrapping.
2.Excellent Barrier Protection
Aluminum foil provides a near-total barrier against moisture, oxygen, light, and aromas, extending product shelf life and preserving flavor and potency.
3.Superior Lamination Performance
The clean, oil-free surface and high wettability of 8011 O make it ideal for lamination with PE, PET, paper, and other substrates, ensuring strong, consistent bonding.
4.Pinhole-Free Consistency
The refined grain structure of the 8011 alloy minimizes pinholes, delivering reliable barrier integrity even at ultra-thin gauges.
5.Food-Safe and Hygienic
Produced with a non-toxic, non-porous surface, 8011 O foil complies with international food-contact safety requirements.
Global Industry Applications
The versatility of aluminum foil 8011 O makes it indispensable across multiple sectors:
- Food Packaging: Chocolate and candy wrapping, dairy lids (yogurt/butter), tea and coffee pouches, ready-meal containers, and household kitchen foil.
- Flexible Packaging & Lamination: Aluminum-plastic and aluminum-paper laminates for snacks, seasonings, and liquid packaging.
- Pharmaceutical Packaging: Blister pack lidding foil, strip packaging, and sachets requiring high barrier protection.
- Container Foil: Semi-rigid foil containers for airline catering, takeaway, and baking trays.
- Insulation & Industrial: Foil-faced insulation, cable wrapping, and technical laminates.
Packaging and Global Logistics
To protect the foil during international transit, Vietnam North Metal uses export-grade packaging:
- Moisture-proof wrapping and inner plastic film
- Sturdy wooden cases or pallets
- Steel strapping and edge protection
We support FOB, CFR, CIF, and other international trade terms according to customer requirements, with reliable global delivery to all major markets.
