Specification
The 8079 aluminum alloy is a member of the Al-Fe-Si family of aluminum alloys. It is produced predominantly from aluminum with small portions of iron (Fe) and silicon (Si) as alloying elements; the alloying elements improve the overall mechanical performance and structural integrity of the alloy.

8079 aluminum foil is more flexible than other grades (such as 8011 and 3003) and can therefore be used in high-end packaging applications.
Another reason why 8079 foil is flexible can be attributed to the metallurgical structure of the foil. 8079 foil has a very fine grain structure that has been developed through modern rolling and processing processes, and therefore, the foil has the ability to bend multiple times without breaking.
8079 foil has also been treated through annealing, which is a method of heating the aluminum in order to relieve stresses and create a very soft metal that will work well with deep-drawing and folding applications.
The thickness of 8079 aluminum foil can also be one of the reasons why it is flexible. It is regularly produced in ultra-thin thicknesses (ranging from 6 to 20 microns) which lend themselves nicely for lamination and multiple layers in packaging systems.
The properties of 8079 flexible aluminum foil include:
* Excellent elongation (ability to stretch) and formability - 8079 foil will stretch or conform to any shape without tearing which is excellent for complex packaging designs.
* Good barrier properties - 8079 provides an excellent barrier to moisture, oxygen, and light (which gives the packaged product a longer shelf life).
Mechanical Strength 8079 Foil is Strong for the Weight
When comparing weights to other aluminium foils, the 8079 foil is still very strong and able to withstand both tensile strength and puncture resistance which gives it a high degree of reliability when shipping it to the customer and during storage.
Food-Grade Safe & Hygienic 8079 Foil Meets All Food Safety Guidelines
Regarding food-grade safety, the way 8079 will be safe to come into contact with food and/or pharmaceuticals is that 8079 foil is non-toxic, odourless, and resistant to being tainted to give a sanitary and healthy surface to touch food and/or pharmaceutical products.
Applications for 8079 Flexible Aluminium FoilPharmaceutical Packaging: Blister Packs & Strip Packs: High Barrier Protection & Precision Formed
Food Packaging: Laminated Foil & Flexible Pouches: Used for Snack Foods, Dairy and Ready-to-eat Meals
Cosmetics & Daily Products: Flexible Packaging of Creams/Lotions, and Other Personal Care Products Using the Protective/Aesthetic Properties of Foil
Industrial: 8079 Foil Can Be Used in Multiple Ways for Industrial Applications Including Insulating Materials, Cable Wrapping and Any Application That Requires Flexibility and Durability.
Advantages of Flexible Aluminium Foil are:
Superior Flexibility (Excellent for Complicated/High-speed Converting Processes)
Light weight/Strong (Less Overall Material Usage)
Outstanding Process Compatibility (Ideal for Laminating, Printing and Coating)
Cost Savings (Reduces Waste/Greater Efficiency While Converting and Packing Product)
Overview of Flexible Packaging Aluminium Foil
8079 aluminum foil is a key material in flexible packaging systems, often combined with plastic films or paper layers to form multi-layer laminates. These structures enhance mechanical strength while maintaining barrier properties.
Layer Structure Example Function
PET / AL / PE Strength + Barrier + Sealing
BOPP / AL / CPP Printability + Protection
Paper / AL / PE Eco-friendly + Barrier
8079 flexible aluminum foil offers an outstanding combination of flexibility, strength, and barrier performance. Its ability to perform in ultra-thin formats while maintaining durability makes it a preferred choice in high-end packaging applications.
The increased desire for eco-friendly and effective packaging is anticipated to lead to greater levels of consumption of 8079 aluminum foil. 8079 aluminum foil is a reliable and versatile package that is likely to be used extensively across multiple markets (food and pharmaceuticals).
Frequently Asked QuestionsQ1: What does 8079 foil typically get used for?Flexible packaging; food, medical, and beauty products all typically use 8079 foils as they provide great barrier properties while giving flexibility when comparing them to other materials used in flexible-packaging products.
Q2: How does 8079 differ from 8011 foil?8079 foil provides better flexibility and strength than 8011 foil, making 8079 foil ideal for ultra-thin laminating and laminated-finished packaging, whereas 8011 foils are typically used for consumer (household) foils.
Q3: Is it safe to use 8079 foil for food-contact applications?Yes, 8079 foil is a food-grade, non-toxic, hygienic material that meets international food-safety requirements.
Q4: What are the typical thicknesses for 8079 foil?8079 foils are typically between 6 microns (0.006mm) and 20 microns (0.020mm), depending on the end use.
Q5: Is it possible to print or laminate on 8079 foil?Yes, 8079 foils are very compatible with printing, coating and lamination, making them ideal materials for branded packaging products.
