Home > News & Blog > Blog > 8021 aluminum foil VS 8079 aluminum foil
8021 aluminum foil and 8079 aluminum foil are two commonly used aluminum foil materials, both of which are widely used in packaging fields, such as battery soft packs, food packaging, and pharmaceutical packaging. They share some similarities, as well as significant differences, in their composition, properties, and applications.
◆ Production specifications
The product specifications of 8021 aluminum foil and 8079 aluminum foil are relatively similar. Commonly used temperaments include O, H14, H16, H18, etc. The thickness range is usually between 0.018mm and 0.5mm. The width can be customized according to customer needs, usually between 100mm and 1600mm.
◆ Basic features
Both 8021 aluminum foil and 8079 aluminum foil are non-toxic, odorless, safe and hygienic, and comply with safety standards for food and pharmaceutical packaging.
◆ Application areas
Both are widely used in lithium battery soft packaging aluminum-plastic films, food packaging, pharmaceutical packaging, etc., and have good moisture-proof and barrier properties.
| Characteristic | 8021 Aluminum Foil | 8079 Aluminum Foil |
| Alloy composition | Mainly composed of aluminum, silicon and a small amount of iron | Main components are aluminum and manganese |
| Strength | Moderate strength, suitable for general use | High strength, tensile strength can reach 90-110MPa |
| Ductility | Good ductility, suitable for cold stamping | Better elongation and compressive strength, suitable for high strength requirements |
| Moisture resistance | Excellent moisture-proof performance, suitable for long-term storage | Good moisture-proof performance, more suitable for high-demand packaging |
| Surface properties | Smooth surface, suitable for lamination and printing | High surface gloss, easy to process into various patterns and designs |
| Application preferences | Commonly used in battery soft packs and food packaging | Commonly used in pharmaceutical packaging and high-end food packaging |
8021 aluminum foil and 8079 aluminum foil have their own characteristics. 8021 aluminum foil is suitable for general packaging needs, especially in battery soft packs and food packaging; while 8079 aluminum foil is suitable for applications with higher mechanical properties requirements, such as pharmaceutical packaging and high-end food packaging, due to its higher strength and ductility. When choosing, you should decide which aluminum foil to use based on the specific application needs and performance requirements.
