8011 1235 8079 aluminium foils
Aluminium foil is a versatile and essential material found in numerous industrial and consumer applications. Among the most commonly used grades are 8011, 1235, and 8079 aluminium foils. Each variant presents unique characteristics that cater to specific applications.
Overview of Aluminium Foils
Aluminium foils are thin sheets of aluminium created by rolling metal to a thickness that often measures just a few microns. Not only do they provide excellent barrier properties against moisture, oxygen, and light, but they also offer forms of reflectivity and electromagnetic shielding depending on the structured orientation.
1. 8011 Aluminium Foil
The 8011 alloy is widely recognized for its advantageous physical and mechanical properties. Primarily composed of aluminium with small additions of iron and lithium, 8011 aluminium foil boasts excellent formability and strength.
Key Applications:
- Food Packaging: The primary use of 8011 is in the food industry due to its promotional advantages in maintaining food freshness and flavor.
- Pharmaceuticals: Its non-toxic and sterile attributes make it ideal for pharmaceutical packaging applications.
- Flexible Insulation: 8011 foil forms an effective barrier in insulation wrappings and is utilized within HVAC products.
2. 1235 Aluminium Foil
1235 aluminium foil is distinguished by its high aluminium content (minimum of 99.35%), leading to superior ductility and a pristine surface finish.
Key Applications:
- Food and Beverage: Like 8011, 1235 is also extensively used in the food and beverage industry, offering an outstanding balance of breathability and protection.
- Wrappers and Labels: A common choice for wrappers due to its high reflectivity and printability, 1235 can support vibrant colors and branding on packaging.
- Electrolytic Capacitors: its thin gauge and deficit in impurities make it an apt choice for specific electronic components.
3. 8079 Aluminium Foil
8079 aluminium foil is a premium-grade alloy possessing optimal properties which enable it to tackle various personal and industrial applications. The foil strength, resistance to wearing, combined with a good formability, makes 8079 an efficient choice.
Key Applications:
- Flexible Containers: Due to its excellent barrier characteristics, 8079 is used in film-based laminates for first-class flexible packages.
- Pharmaceuticals: Like 8011, it is also employed in medical packaging functions where protection and sterile conditions are paramount.
- Construction and Craftsmanship: 8079’s strength provides support for many industrial crafts where thinner yet resistant materials are sought.
How to Choose the Right Aluminium Foil
Selecting the appropriate aluminium foil largely depends on your end-use and specific requirements. Consider the following factors:
-
Barrier Needs: Assess the level of imperviousness required to protect contents from moisture, oxygen, and light.
-
Racking Scheme: Consider if lightweight will influence your packaging dynamics, where a thinner gauge foil could optimize material use.
-
Compatibility: Determine if your product needs a specific certification, focusing on food-life safety or specific license claims pertinent to pharmaceuticals.
