As a member of the 8xxx series (aluminum-silicon alloys), 8011 aluminum alloy stands out in food packaging for its unique blend of purity, formability, and safety compliance. With a minimum aluminum content of 99.0% and trace silicon additions (0.5–0.9%), it offers superior performance in applications where hygiene, durability, and flexibility are non-negotiable.
Characteristics of Alloy 8011
Its strength lies between that of the 1-series and 3-series. In the application of aluminum foil, it has higher strength than the 1-series and better toughness than the 3-series. Therefore, in many aluminum foil applications, the 8-series is chosen, among which the 8011 alloy has a relatively large usage amount.
In the application of aluminum sheets, the 8011 aluminum sheet is inferior to the 1060 pure aluminum in terms of thermal and electrical conductivity, and is also inferior to the 3003 alloy in terms of corrosion resistance and strength. As a result, the application of 8011 aluminum sheets is relatively limited.
Temper of Alloy 8011 and properties
The commonly used alloy tempers for 8011 aluminum alloy are: O, H14, and H18.
The O temper is the annealed (softest) condition.
The H14 temper is the condition where the grains are hardened to a semi - hard state.
The H18 temper is the condition where the grains are hardened to a fully - hard state.
Common Applications in Food Packaging
Aluminum Foil:
Used for wrapping sandwiches, baking sheets, and household foil rolls. Its thinness and flexibility enable easy handling while maintaining structural integrity.
Lidding Films & Capsules:
Seals for yogurt cups, beverage cans, and glass jars, providing a tamper-evident barrier and extending shelf life.
Pre-Formed Trays & Containers:
Deep-drawn trays for ready meals, frozen dinners, and airline food, offering heat resistance and stackability.
Flexible Packaging:
Laminated with plastic or paper to create pouches for snacks, grains, and pet food, combining the alloy’s barrier properties with mechanical strength.
Beverage Can Liners:
Internal coating in aluminum beverage cans to protect against corrosion from acidic liquids (e.g., soda, juice).
