8011 0.006mm Double Zero Aluminum Foil For High End Food Packaging

Double zero aluminum foil refers to high-quality aluminum foil that has been rolled and processed on both sides, with a smooth surface and no flaws or defects. The "Double Zero" designation means both sides of the aluminum foil have reached the zero-defect standard, which is the defining characteristic of Double Zero foil.

The manufacturing process of double zero aluminum foil is very strict:

1. Coil preparation: Begins with melting aluminum ingots, then transforming the molten aluminum into foil coils through continuous casting and rolling processes.
2. Hot rolling and cold rolling: Aluminum foil coils undergo both hot rolling (heating and rolling to reduce thickness) and cold rolling (further stretching and thinning to achieve desired thickness).
3. Hardening and softening: Can be hardened through heat treatment for increased strength or softened (O temper) to reduce hardness and improve formability.
4. Cutting and processing: Cut to required dimensions and can undergo additional processes like printing or coating as needed.

• High-end food packaging: Ideal for chocolate, candy, dairy products, coffee, and tea packaging due to its thinness and ability to maintain freshness.
• Aluminum foil food containers: Used for lunch boxes, bakeware, and food trays thanks to excellent heat conduction and food safety properties.
• High-temperature baking: Suitable for oven liners, baking sheet mats, and oven bags due to high-temperature resistance.
• Electronic materials: Used in electronic component packaging and battery isolation films due to thinness and conductive properties.
