Aluminum Alloy 8079 Aluminum Foil for Industrial Lamination I Ultra Thin 0.006-0.009mm I Customized Width I Primer Coated

Introduction                                                

The 6–9 μm 8079 primer coated aluminum foil represents the cutting-edge ultra-thin high-performance grade for industrial lamination applications where extreme thinness, superior mechanical properties and reliable barrier performance are required without compromising processability.

Compared to 8011 or 1235 (more common for general flexible packaging), 8079 in this ultra-thin range excels due to:

Engineered higher elongation & tensile balance → resists cracking during lamination & forming

Minimal pinhole occurrence even at 6–9 μm → maintains true barrier integrity

Optimized surface quality & primer adhesion → stronger bonding in multi-layer structures

Cost-effective solution for lightweight, high-value industrial composites

Primer/Coating system:Pharma/food-grade primer (acrylic/vinyl-based, low-migration),Enhances adhesion to PET, PE, PP, BOPP, paper or other substrates,Barrier: OTR <0.005 cc/m²·24 h, WVTR <0.005 g/m²·24 h (post-lamination),Compliance: FDA 21 CFR 175.300, EU 10/2011, GB 9685 (for food-contact grades)

FAQ (USA/Europe/Middle East/Asia Buyers)

Q1: Why choose 8079 over 8011 or 1235 for ultra-thin industrial lamination?

A: 8079 has higher elongation & tensile balance in 6–9 μm gauges → better crack resistance during deep lamination & forming. It also shows lower pinhole density and stronger multi-layer bonding than 8011/1235, making it superior for high-performance barriers.

Q2: What is the actual pinhole rate at 6–9 μm & how does it affect barrier?

A: ≤15–25 pinholes/m² — extremely low for ultra-thin foil. Ensures OTR/WVTR remain <0.005 after lamination, critical for long-term protection in electronics & sensitive packaging.

Q3: Can you provide compliance certificates & migration/leachability test reports?

A: Yes — full package including FDA 21 CFR 175.300, EU 10/2011, GB 9685 (food/pharma grades) + third-party migration reports (SGS/Intertek). Supports regulatory submissions.

Q4: Minimum order quantity & lead time for custom primer or thickness?

A: MOQ 3–5 tons (depending on spec); standard 6–9 μm primer coated 15–25 days; custom primer or gauge 25–35 days. Small sample rolls free with freight collect.

Q5: How does 8079 perform in high-humidity / extreme temperature lamination processes?

A: Excellent — passes 40 °C / 90% RH aging & thermal cycling (–40 °C to +80 °C) without delamination or barrier loss. Humidity & temperature test data available.

Q6: Is 8079 suitable for mono-material recyclable laminates?

A: Yes — optimized for PE/PP + aluminum structures. Enables lightweight, high-barrier recyclable films. We provide mono-material lamination samples & recyclability reports.
