Packaging Foil 8011 & 8079: Find Your Fit

In the modern packaging industry, aluminum foil is renowned as the "golden armor" for protecting food, pharmaceuticals, and even industrial products, thanks to its exceptional barrier properties, safety, and versatility. Among the various aluminum alloy grades, why have 8011 and 8079 packaging foil emerged as the dominant stars? How can you make the best choice for your product? As a specialized aluminum foil supplier, Mingtai Aluminum provides this detailed analysis to guide you.

The Contenders: Why Do 8011 and 8079 Dominate?

Before comparing them, it's essential to understand their shared, superior qualities. Both 8011 and 8079 offer the core benefits of high-quality aluminum foil:

*   Superior Barrier: They effectively block moisture, oxygen, and light, preventing spoilage, oxidation, and extending shelf life.

*   Safety & Hygiene: Their surfaces are clean, sterile, non-toxic, and odorless, meeting strict hygiene standards for food and pharmaceutical packaging.

*   Eco-Friendly & Recyclable: Aluminum is a green material that can be recycled infinitely, aligning with modern sustainability goals.

*   Excellent Formability & Lamination: They are easily pressed, folded, and perfectly bonded with plastics and papers to create versatile packaging structures.

The uniqueness of 8011 and 8079 lies in how they have each specialized for different applications within these shared advantages.

Deep Dive: 8011 Aluminum Foil – The King of Deep Drawing

Key Characteristic: Excellent deep-drawing performance and flexibility are the hallmarks of 8011 foil. Its specific alloy composition and annealing process create a uniform, fine-grained structure that resists cracking during severe stretching and forming.

Common Applications:

*   Food Packaging: It is the ideal material for yogurt lid foil, jelly cup seals, and meal box lidding film, offering easy peeling and reliable sealing.

*   Pharmaceutical Packaging: 8011 is the primary material for PTP (Push-Through Pack) blister foil, where it is precisely formed into blisters, protecting tablets while allowing easy push-through.

*   Other Packaging: Such as laminated tubes (for ointments, cosmetics), which require a material that can withstand repeated folding and squeezing.

In Summary: When your packaging design involves deep drawing or stamping, 8011 aluminum foil is the unequivocal choice.

Deep Dive: 8079 Aluminum Foil – The Guardian of Strength & Barrier

Key Characteristic: Higher strength and superior barrier properties define 8079 foil. Its alloy formula provides greater mechanical strength and puncture resistance compared to 8011 at similar thicknesses, offering more robust protection.

Common Applications:

*   Flexible Laminated Pouches: Widely used for snack bags (e.g., chips, nuts), retort pouches, and stand-up pouches. Here, 8079 acts as the core barrier layer, providing crucial protection against moisture and oxygen.

*   Heavy-Duty Packaging: For products requiring greater durability, such as industrial product packaging or large food packages, 8079 better withstands external pressures during shipping and storage.

*   Sealing Layer: Often used as the sealant layer in various flexible packages, where its strength ensures seal integrity.

In Summary: When your packaging prioritizes overall toughness, puncture resistance, and maximum barrier protection, 8079 aluminum foil is the more reliable solution.

The Final Comparison: 8011 vs. 8079 – A Selection Guide

Use this comparison table to aid your decision-making:

How to Decide?

Ask yourself two simple questions:

1.  Does my packaging require deep stamping to form specific shapes? (e.g., creating tablet blisters or yogurt lid cavities)

*   Yes -> Choose 8011

2.  Is my packaging more about overall durability and extreme barrier protection? (e.g., a laminated pouch that needs stacking and shipping)

*   Yes -> Choose 8079

Final selection may also depend on specific gauge, width, and temper, which is where a expert supplier adds value.
