Battery flexible packaging consists of a nylon layer, aluminum foil layer, heat-sealing layer, and adhesive. The aluminum foil, primarily made of 8021 or 8079 alloy (O temper), serves as the core material. The aluminum-plastic film requires high barrier properties, excellent cold punching formability, puncture resistance, electrolyte stability, heat resistance, and insulation. These performance demands necessitate high technical standards and strict material requirements.
In pharmaceutical packaging, aluminum foil is widely used due to its stability and reliability. 8021 aluminum foil is ideal for blister packaging (pharmaceutical packaging aluminum foil). High-quality pharmaceutical packaging imposes strict requirements on harmful element content, flatness, thickness, surface quality (e.g., color deviation, streaks, bright spots), pinholes, heat resistance, and heat-seal strength. Mingtai Aluminum focuses on critical production processes to ensure compliance with industry standards.
Composition: 8011 foil contains Mn and Mg, while 8021 does not, giving 8011 higher strength and corrosion resistance.
Performance: 8011 has higher strength but lower elongation and puncture resistance than 8021. Thus, 8021 is preferred for blister packaging requiring superior sealing and flexibility.
Applications: 8011 is versatile, used in food packaging, meal containers, adhesive tape, and cables, while 8021 is mainly applied in high-end lithium battery films and pharmaceutical blister packs due to its premium price.
