It serves as the preferred substrate for high-speed automated packaging lines and the core functional material for high-end composite soft packaging, offering significant advantages over traditional 8011 és 1235 sorozat.
én. Core Product Definition
8079 H14 Heat-Sealable Aluminum Foil is a functional aluminum foil made from an 8079 aluminum alloy base and processed via the H14 semi-hard temper. It is specifically engineered for composite heat-seal packaging.
H14 Temper: The Golden Balance
The H14 semi-hard state is the key to its performance, achieving a perfect equilibrium between material strength and processing toughness. It effectively avoids the insufficient strength and vulnerability to breakage found in soft-tempered foil (O-mérséklet), while solving the poor processability and unstable heat sealing often seen in full-hard temper foil.
Microstructural Advantages
Compared to the industry-standard 8011 ötvözött fólia, 8079 features a superior iron content range, a lower pinhole rate, and a more uniform microstructure. It possesses stronger puncture resistance, tear strength, and exceptional barrier properties, making it the exclusive choice for high-end, nagy akadályú csomagolási forgatókönyvek.
II. Chemical Composition and Mechanical Properties
1 Kémiai összetételi elemzés
Precise control of material composition is the foundation of stable performance. The strict chemical ratio ensures a unity of purity and functionality.
| Ötvözet elem | Tartalom szabvány (%) | Funkció & Benefit |
|---|---|---|
| Al (Alumínium)) | ≥99,3 | Ensures flexibility and processing adaptability. |
| Fe (Vas)) | 1.0 – 1.5 | Enhances structural strength, szúrás, és szakadásállóság (Alapvető előny). |
| És (Szilícium)) | 0.05 – 0.30 | Optimizes rolling performance, ensuring uniform thickness. |
| Cu, Mn, Mg, Zn | ≤0,05 – 0.10 | Strictly controlled to prevent oxidation and pinhole defects. |
2 Mechanikai teljesítmény & Műszaki adatok
8079 H14 demonstrates strong adaptability to various scenarios. In the standard H14 state, the tensile strength is stable at 120-160 MPa, with an elongation of 2%-6%.
- Vastagsági tartomány:) 0.006 – 0.050 mm
- Szélesség tartomány:) 100 – 1600 mm
Its semi-hard structure provides excellent puncture and tear resistance, effectively handling sharp-edged products, long-distance logistics, and stacking pressure.
III. Alkalmazási mezők
1 Élelmiszer -csomagolás

V. Gyakran Ismételt Kérdések (GYIK)
Q1: Tud 8079 H14 be used for direct heat sealing?
Nem. This product is a base foil and does not have a built-in heat-seal layer. It must be laminated with films like PE, CPP, or VMCPP to achieve a stable seal. It serves as the core middle layer of multi-layer packaging.
Q2: Is it suitable for vacuum and nitrogen-flushed packaging?
Igen. Its dense structure and high mechanical strength effectively maintain a sealed environment, preventing gas penetration or bag inflation.
Q3: Does it support customization?
Igen. We offer full-spec customization for thickness (0.006–0.050mm), szélesség, and surface status (single/double light, coating-grade, stb.).
