- Excellent punching and puncture resistance: Its elongation rate can reach 13%-18%, and the cup height can reach 7.3mm.
Application
Alu alu pharmaceutical foil
Pharmaceutical foil is divided into two types: blister foil and alu alu foil. One side of the blister foil is plastic and the other side is aluminum foil. Alu alu foil has aluminum foil on both sides. Therefore, alu alu foil has higher requirements for sealing and elongation. It usually uses aluminum foil of 8021 and 8079 alloys.
Battery Soft pack foil
Compared with traditional batteries, batteries made of 8021 aluminum foil are lighter, thinner, have longer cycle life, good safety, high energy density, excellent power performance, and are environmentally friendly and pollution-free.
Label foil
8021 aluminum foil has the characteristics of cleanliness and hygiene, and can be made into integrated packaging materials with many other packaging materials. In addition, the surface printing effect of 8021 aluminum foil is better than other materials. Therefore, 8021 aluminum alloy is also commonly used in beer packaging.
The difference between 8011 aluminum foil and 8021 aluminum foil
8011 aluminum foil has higher strength, but its elongation and puncture resistance are lower than 8021 aluminum foil. Therefore, 8021 aluminum foil is relatively expensive and is mostly used in the packaging of soft aluminum-plastic films for lithium batteries and blister pharmaceuticals that require relatively high requirements. 8011 aluminum foil is widely used and can be used in many fields such as pharmaceutical packaging, food packaging, lunch box materials, tape foil, cable foil, milk cap materials, bottle cap materials, etc.
Production Process
The aluminum foil manufacturing process generally goes through casting, homogenization, surface treatment, hot rolling, cold rolling, foil rolling, cleaning, winding, annealing, and finally cutting.
