Aluminum Foil Coil Sheet Soft Foil 0.1～0.2mm For Food Packaging

Description

Aluminum foil is a hot-stamping material made from metal aluminum rolled directly into thin sheets. Its hot-stamping effect is similar to that of pure silver foil, earning it the nickname “false silver foil.”
Thanks to its soft texture, good ductility, and bright silver-white luster, aluminum foil can be laminated with sodium silicate and other materials on offset paper to produce printable aluminum foil sheets.
However, aluminum foil easily oxidizes and darkens over time. Friction and frequent handling can cause fading, making it unsuitable for long-term decorative uses such as book covers or other hot-printing applications.

Specification

Characteristics

1. Clean and hygienic surface – resistant to microbial growth.

2. Non-toxic and safe – suitable for direct contact with food.

3. Odorless and tasteless – maintains the original flavor of packaged food.

4. Stable and non-volatile – prevents packaged food from drying or shrinking.

5. Grease-resistant – no oil penetration at high or low temperatures.

6. Opaque – ideal for light-sensitive products such as margarine.

7. Excellent plasticity – easy to shape and form into various containers.

8. High hardness and tensile strength, but low tearing strength – easy to tear.

9. Not heat-sealable by itself – requires a heat-sealable coating (e.g., PE layer).

10. Reactive with certain metals – avoid direct contact with heavy metals.

Applications

1. Food Packaging:
Used extensively in candy wraps, cigarette packaging, and household containers (e.g., foil lunch boxes) due to its flexibility, moisture resistance, and decorative finish. It helps distribute heat evenly and preserves food freshness.

2. Automotive Industry:
Applied in the production of heat exchanger fins for automotive air conditioners to enhance cooling efficiency.

3. Pharmaceutical Industry:
Used for packaging capsules, tablets, and powders, providing moisture resistance, light protection, and corrosion resistance.

4. Energy and Electronics:
Aluminum foil serves as a key material in lithium batteries (as a positive current collector) and electrolytic capacitors requiring high-purity aluminum for reliable performance under polar conditions.
