3 Physical Properties of Aluminum Foil

The aluminum foil is widely used in the packaging of cigarette, medicine and food, the cable wrapping, air conditioner, battery making, electronic label,etc. Its wide application is owed to its excellent aluminum foil properties. There are its main physical properties:

1. Weight: 145-155 g/m2

2. Tensile breaking strength: 665 N/25×100mm in vertical direction; 395 N/25×100mm in horizontal direction.

3. Elongation at break: It is 5.4% in longitudinal direction and 4.7% in transverse direction.

4. Water vapor permeability: 0.28g/m2 in 24 hours.

5. Temperature resistance: It is of smooth surface, no cracking and no degumming and has no change in the -15℃ and 80 ℃ for 24 hours.

6. Bursting strength: 332N
