Chemical composition and alloy family

8079 is part of the 8000 アルミニウム合金シリーズ, which are aluminum-magnesium or aluminum-magnesium-silicon alloys designed for ductility, 成形性, and good barrier properties.

While exact compositions can vary by mill and temper, 8079 foil is typically produced from an aluminum base with a composition optimized for thin-gauge foil that can be easily laminated and sealed in food packaging structures.

The alloy’s inherent properties—excellent surface finish, good drawability, and compatibility with coatings and laminates—make it well-suited to snack packaging applications that require high-speed converting and reliable heat-seal performance.

Temper and processing considerations

Foil used for snack packaging often features tempers that balance formability with stiffness, such as partial annealing or specific heat-treat cycles designed for thin gauges.

実際に, 8079 アルミホイル used for snack packaging is produced in gauges that promote strong barrier behavior without sacrificing the ability to print, laminate, and seal efficiently.

Temper choice affects not only mechanical performance but also printability and lamination adhesion, so converters typically select the temper based on the downstream packaging structure (例えば, single- or multi-layer laminates, sealant layers, and coatings).

Core properties and advantages
