The difference between 8011 aluminum foil and 8079 aluminum foil
| Property | 8079 Foil | 8011 Foil |
|---|---|---|
| Strength | Higher | Medium |
| Elongation | Excellent | Good |
| Puncture Resistance | Superior | Standard |
| Packaging Use | Pharma / Battery | Food / Household |
| Barrier Performance | High | Medium |
Corrosion resistance
The Si content of 8011 aluminum foil is higher than that of 8079 aluminum foil, and 8011 aluminum foil contains Mn and Mg elements, while 8079 aluminum foil does not contain these two elements, so the strength and corrosion resistance of 8011 aluminum foil are higher than 8079 aluminum foil;
Metal strength
Aluminum foil 8011 has high strength, but the corresponding elongation and puncture resistance in the same state are lower than that of 8079 aluminum foil. Therefore, in drug packaging, the aluminum foil coating on the back of the drug bag drug board is mostly 8011 aluminum foil, and the sealing and Blister aluminum and tropical aluminum with higher elongation requirements mostly use 8021 aluminum foil and 8079 aluminum foil;
Application
Aluminum foil 8011 is more widely used and can be used in many fields such as drug packaging, food packaging, lunch box material, tape foil, cable foil, milk cap material, bottle cap material, etc., while 8079 aluminum foil is relatively expensive and is mostly used for relatively high requirements. High lithium battery soft-wrapped aluminum-plastic film and blister drug packaging.

Exceptional Properties
High Strength with Good Elongation
8079 aluminum foil offers relatively high strength, which makes it suitable for applications that require durability. At the same time, it has excellent elongation and stretchability. This means that it can be easily formed into different shapes without cracking or breaking. For example, in the manufacturing of complex - shaped food containers or battery soft - pack casings, the ability of 8079 aluminum foil to stretch and conform to the required shape is highly beneficial.
Excellent Barrier Properties
One of the most significant advantages of 8079 aluminum foil is its outstanding barrier properties. It has extremely high moisture resistance, gas impermeability, and flavor retention. This makes it an ideal material for protecting products from external factors. For instance, in food packaging, it can prevent moisture from entering, which helps to keep the food fresh, crispy, and free from spoilage. In pharmaceutical packaging, it effectively blocks oxygen and other gases, ensuring the stability and efficacy of drugs over an extended period.
Good Surface Quality
Our 8079 aluminum foil features a smooth and clean surface. It has been thoroughly degreased, resulting in a surface that is free from oil stains. Additionally, it has a low pinhole count, which further enhances its barrier performance. The excellent flatness of the foil ensures that it can be processed easily in subsequent manufacturing steps, such as printing, laminating, or forming.
Diverse Applications
Food Packaging
8079 aluminum foil is widely used in food packaging. It can be found in various forms, such as food wrapping foil, meal box materials, and packaging for dairy products. Its ability to maintain the freshness, flavor, and nutritional value of food makes it a popular choice among food manufacturers. For example, it is commonly used to wrap cheese, meats, and baked goods, protecting them from moisture, oxygen, and odors. The elegant silver - white luster of the foil also adds an aesthetic appeal to the food packaging.
Pharmaceutical Packaging
In the pharmaceutical industry, 8079 aluminum foil plays a crucial role in ensuring the quality and safety of medications. It is used for packaging capsules, tablets, and other pharmaceutical products. The foil's barrier properties protect drugs from environmental factors like humidity, light, and oxygen, which can degrade the active ingredients. For PTP (Press - Through Packaging) of drugs, 8079 aluminum foil provides a reliable and easy - to - use packaging solution. It also serves as a good substrate for printing important information about the medicine, such as dosage, usage instructions, and expiration date.
Battery Soft - Pack Applications
8079 aluminum foil is an essential component in battery soft - pack manufacturing. As a part of the battery packaging, it provides protection to the battery cells. The foil's lightweight nature, due to the low density of aluminum, helps to reduce the overall weight of the battery, which is especially important for portable electronic devices like smartphones and tablets. Its excellent corrosion resistance ensures the long - term stability and performance of the battery. It also has good electrical conductivity, which is beneficial for the proper functioning of the battery.
Stringent Production Process
High - quality raw materials, including a certain proportion of pure aluminum ingots and carefully selected recycled materials (when applicable), are melted in state - of - the - art furnaces. The melting process is closely monitored to ensure a homogeneous melt. After melting, the molten aluminum is cast into billets with strict control over the casting parameters to achieve the desired microstructure.
The cast billets are then hot - rolled at a specific temperature range, typically between 320 - 360 °C. This hot - rolling process helps to break down the as - cast structure, improve the mechanical properties, and reduce the thickness of the billets to an intermediate thickness, usually around 3.0 - 5.0 mm. The hot - rolled products are carefully inspected for surface quality and dimensional accuracy.
The hot - rolled sheets are further cold - rolled in multiple passes. The cold - rolling process significantly improves the surface finish, flatness, and mechanical properties of the aluminum foil. Intermediate annealing may be carried out during the cold - rolling process to relieve internal stresses and improve the formability of the material. The final thickness of the aluminum foil can be precisely controlled according to customer requirements, ranging from 0.02 mm to 0.2 mm.
In the foil - rolling stage, the cold - rolled sheets are rolled into thin foils. Specialized rolling mills with precise control systems are used to ensure a uniform thickness and high - quality surface. Advanced additives and lubricants are used during foil rolling to improve the rolling process and the quality of the final product.
After the production process, each batch of 8079 aluminum foil undergoes a comprehensive quality inspection. This includes checks for thickness uniformity, surface quality (such as pinhole count, oil stains, and scratches), mechanical properties (tensile strength, elongation), and barrier properties (moisture and gas permeability). Only products that meet our strict quality standards are released for shipment.
