Features

Aluminium degreased foil refers to aluminium that has undergone a special cleaning process to remove oils or lubricants from its surface. Key characteristics of degreased aluminium foil include:

1. Increased Adhesion: By eliminating oils and lubricants from its surface, aluminium foil exhibits improved adhesion to other materials – making it an excellent solution for applications requiring strong bonding capabilities.

2. Clean Surface: Degreased aluminum foil features an oil-free surface that allows for greater accuracy and consistency during downstream processing operations, such as printing or coating.

3. Increased Surface Energy: When degreasing aluminium foil, its cleaning process increases its surface energy, making it more receptive to inks, coatings and adhesives that will enhance quality and durability of finished products.

4. Improved Wettability: An increase in surface energy can also result in improved wettability of foil surfaces, providing greater penetration and adhesion of coatings or adhesives to them.

5. Decreased Risk of Surface Defects: Eliminating oils and lubricants reduces the likelihood of surface defects such as pinholes or streaks, creating more uniform and reliable end products.

6. Corrosion Resistance: Aluminium degreased foil offers greater corrosion resistance due to the absence of oils or lubricants on its surface, making it suitable for use in harsh environments.

7. Lightweight and Flexible: Aluminium degreased foil is lightweight and flexible, making it easier to manage than many other options and suitable for various uses, including packaging, insulation and electronics applications.

8. High Thermal Conductivity: Aluminium’s excellent thermal conductivity makes degreased aluminium foil an ideal choice for applications requiring efficient heat transfer.

9. High Barrier Properties: Aluminium degreased foil provides excellent barrier properties against moisture, gasses and odours – an essential trait when it comes to food packaging and other applications requiring high levels of protection. It makes the perfect material choice.

10. Customizable: Aluminium degreased foil can be customized in terms of size, thickness, and surface treatment to meet specific industry applications, such as pharmaceuticals, cosmetics and automotive.
