8011 H22 0.08mm Large Aluminum Foil
Aluminum foil has become an indispensable material in various sectors due to its versatility, lightweight properties, and durability. Among the many products available in the market, the 8011 H22 0.08mm large aluminum foil stands out for its unique features and applications.
What is 8011 H22 Aluminum Foil?
8011 H22 aluminum foil is part of the 8000 series aluminum alloys, specifically tailored for high-demand applications that include packaging, insulation, and other special purposes. The "H22" designation indicates that the foil has been work-hardened and is partially annealed. The thickness of 0.08mm adds to its strength while retaining flexibility.
Features
- Lightweight and Flexible: Aluminum foil is incredibly light, making it easy to handle, transport, and use in applications.
- Barrier Properties: The foil effectively protects against moisture, gases, and light, preserving the quality of food and goods packed within it.
- Corrosion Resistance: Aluminum forms an oxide layer that shields the aluminum beneath it from various corrosive environments.
- Adds Minimal Weight: Its thin profile allows it to add minimal bulk when packaging components.
Applications of 8011 H22 Aluminum Foil
This aluminum foil variant is widely used in multiple sectors. Below are the most prominent applications:
- Food Packaging: Commonly used to wrap food items, thanks to its excellent barrier properties against light and moisture.
- Pharmaceutical Packaging: Ideal for packaging tablets and other medications, maintaining product stability.
- Insulation: Serves as thermal insulation in buildings and HVAC systems due to its heat-reflecting surface.
- Laminates: Often used in coatings or laminates for enhanced product durability.
- Containers and Foil Sheets: Sometimes established in small disposable containers to prepare or cook meals.
