1235 Aluminum Foil
1235 Aluminum Foil
High Purity | Industrial Grade for Global Packaging Converters
Product Overview
1235 Aluminum Foil is a high-purity aluminum material (Al ≥ 99.35%) designed for flexible packaging and industrial lamination applications.
It is widely used in continuous high-speed converting processes due to its stable mechanical properties, excellent formability, and superior barrier performance.
Typical applications include:

Key Advantages
1. High Purity Aluminum Base (≥99.35%)
High purity ensures stable composition and reduces process variability during rolling and lamination.
Result:
- Consistent mechanical performance
- Lower defect rate in converting processes
- Improved long-term production stability
2. Excellent Formability & Processing Stability
1235 aluminum foil in fully annealed condition provides excellent ductility and elongation stability.
Key benefits:
- Stable performance in high-speed converting lines
- Reduced risk of cracking or tearing during lamination
- Lower downtime in production environments
- Improved yield rate for converters
3. Superior Barrier Performance
Aluminum foil provides a complete physical barrier against external elements.
It blocks:
- Moisture (H₂O vapor)
- Oxygen (O₂)
- Light exposure
- Odor migration
Technical principle:
A dense metallic crystal structure creates a non-porous barrier layer, resulting in near-zero water vapor transmission rate (WVTR < 0.01 g/m²/day under standard conditions).
4. Stable Surface Quality (100% Coil Inspection)
Each coil is produced under strict surface control and inspection systems.
Quality features:
- Controlled pinhole density (per packaging standard)
- Clean, oil-free surface
- Stable surface tension for lamination processes
- Excellent ink adhesion for printing applications
5. High Stability for Industrial Production Lines
Designed for continuous production environments and high-speed converters.
Benefits:
- Consistent thickness across full coil length
- Stable unwinding and rewinding performance
- Reduced machine stoppage rate
- Higher production yield for converters

FAQ
Q: What is the difference between 1235 and 8011 aluminum foil?
A: 1235 aluminum foil is a high-purity grade with excellent flexibility, mainly used for lamination and flexible packaging.
8011 aluminum foil is an alloy grade with higher mechanical strength, suitable for semi-rigid and structural packaging applications.
Q: Is 1235 aluminum foil suitable for food and pharmaceutical packaging?
A: Yes. It can be produced to comply with FDA and EU 10/2011 food contact material requirements depending on application.
Q: How do you ensure batch-to-batch consistency?
A: We use AGC thickness control systems, standardized annealing processes, and 100% inline inspection. Each coil is traceable via a unique coil ID linked to its Mill Test Certificate (MTC).
Q: Can third-party inspection be arranged?
A: Yes. SGS and Bureau Veritas inspection services are available before shipment upon request.
Q: What is your MOQ?
A: MOQ depends on specification and thickness. We support flexible bulk orders for converters and wholesale buyers.
Q: Can specifications be customized?
A: Yes. We support customization of thickness, width, coil diameter, core size, and packaging.
