8079 O 0,010 мм ламинатталған қаптама фольгасы

In the modern flexible packaging industry, aluminum foil has become an indispensable core substrate for high-end packaging due to its excellent barrier properties, қолайлы, және өңдеу мүмкіндігі. Among various options, 8079 O 0,010 мм ламинатталған қаптама фольгасы​ stands out in demanding fields such as food, Фармацевтика, және күнделікті химиялық заттар. It is an ideal choice that balances protective performance with lightweight requirements, thanks to its unique material characteristics and precise process adaptability.

1. Бұл не 8079 O 0,010 мм ламинатталған қаптама фольгасы?

8079 алюминий фольга алюминий қорытпасының фольгаларының 8xxx сериясына жатады. Based primarily on aluminum, it incorporates small amounts of alloying elements to optimize its properties. Through multiple rolling processes, its thickness is precisely controlled to an ultra-thin specification of 0.010мм (10мкм).

Термин “O”​ indicates that the aluminum foil has undergone a full annealing and softening treatment. This process eliminates internal stresses and hardening caused by rolling, bringing the foil to a fully softened state. Осы күйде, it possesses excellent ductility and formability, distinguishing it from hardened tempers (like H-state) and making it highly suitable for complex lamination and forming processes.

While this ultra-thin foil is inherently light and uniform, laminating it with various plastic films creates a composite packaging material that combines multiple functions. This structure retains the core advantages of aluminum foil while compensating for the shortcomings of single-layer foil, such as susceptibility to breakage and poor heat-sealing capability.

2. Chemical Composition and Material Properties of 8079 Алюминий фольга

(1) Main Chemical Composition of 8079 Алюминий қорытпасы

8079 aluminum alloy belongs to the Al-Fe-Si system. Its core chemical composition (Жаппай бөлшек) strictly follows industry standards. As shown in the table below, it also contains trace impurities like Copper (Cu), Магний (Mg), and Manganese (Mn), which are tightly controlled to ensure material purity and performance stability.

• Салыстырғанда 8011 Алюминий фольга:​ 8079 has a slightly higher Iron content and lower Silicon content. This results in superior elongation, қолайлы, and a lower pinhole rate, making it more suitable for ultra-thin specifications and deep-drawing processes.
• Салыстырғанда 1235 Алюминий фольга (Таза алюминий):​ Thanks to its added Iron and Silicon elements, 8079 offers significantly higher strength and puncture resistance while maintaining excellent barrier properties. It avoids the issues of pure aluminum foil being too soft and easily damaged, thus fitting a wider range of packaging scenarios.

The chemical composition design of 8079 is the core foundation that allows it to balance flexibility, күш, және өңдеу мүмкіндігі.

(2) Core Performance of 8079 Алюминий фольга
