Premium Aluminum Foil Solutions for Industrial and Commercial Use

High quality aluminum foil is a vital material in modern manufacturing. Whether you need reliable barriers for food, conductive layers for batteries, or shielding for cables, choosing the right grade is essential. Aluminum foil offers a unique combination of flexibility, strength, and conductivity that few other materials can match.

Diverse Aluminum Foil Alloys and Their Uses

Different industries require specific chemical compositions. We provide a wide range of alloys to ensure your project performs perfectly under pressure.

The 1xxx Series: High Purity and Conductivity

This series contains at least 99% aluminum. It is known for its excellent corrosion resistance and high thermal conductivity.

• 1235 Alloy: Often used for battery current collectors and thin packaging.
• 1060 and 1070 Alloy: Preferred for electrical components due to their superior conductivity.

The 3xxx Series: Strength and Stability

By adding manganese, this series gains higher strength while maintaining good workability.

• 3003 Alloy: A popular choice for food containers and heat exchangers. It stands up well to forming processes without cracking.

The 8xxx Series: The Packaging Standard

This series is specifically designed for high-performance packaging applications.

• 8011 Alloy: The most common alloy for household foil and pharmaceutical packaging.
• 8079 Alloy: Known for high tensile strength and elongation, making it ideal for complex laminate structures.

Technical Specifications by Application Type

To help you choose the right product, here is a breakdown of common specifications based on your specific industry needs.

Battery Grade Aluminum Foil Specifications

Battery foil requires a clean surface and high tensile strength to handle high-speed coating processes.

Cable Shielding Aluminum Foil Specifications

Cable foil, often laminated with PET or EAA, provides an excellent electromagnetic barrier.

Flexible Packaging and Container Foil

Packaging foil must be pinhole-free to protect contents from light, moisture, and oxygen.

High Performance Battery Foil for Energy Storage

In the production of Lithium-ion batteries, aluminum foil serves as the cathode current collector. The quality of the foil directly impacts battery life and safety.

Surface Cleanliness

High-quality battery foil must be free of oil spots and dust. We use advanced cleaning systems to ensure the surface tension is high enough for active material adhesion.

Thickness Consistency

We maintain a thickness tolerance of within ±3%. This precision ensures uniform resistance across the entire battery cell, preventing localized overheating.

Mechanical Properties

The foil must be strong enough (H18 state) to withstand the tension of industrial coating machines. If the foil breaks, it stops the entire production line. Our materials are tested for high tensile strength and elongation.

Reliable Cable Foil for Data and Power Transmission

Aluminum foil plays a critical role in telecommunications. It acts as a shield to prevent electromagnetic interference (EMI).

Shielding Effectiveness

By wrapping wires in aluminum foil, signals remain clear and protected from external noise. This is vital for high-speed internet cables and industrial power lines.

Softness for Wrapping

We typically supply cable foil in the O (annealed) state. This makes the metal soft and flexible, allowing it to wrap tightly around copper wires without snapping.

Composite Options

• AL+PET: Aluminum foil bonded with polyester film for added tear resistance.
• AL+PET+AL: Double-sided shielding for maximum protection.

Packaging Solutions: Safety and Preservation

Aluminum foil is the ultimate barrier material. It blocks everything that could spoil a product: light, oxygen, moisture, and bacteria.

Pharmaceutical Foil

For medicine, safety is the priority. Our 8011 and 8079 alloys are non-toxic and compatible with heat-seal lacquers. This ensures that pills remain effective until the moment the consumer opens the blister pack.

Food Grade Quality

We ensure all food-contact foil meets international safety standards. The foil is sterilized during the high-temperature annealing process, making it safe for direct contact with food.

Heat Resistance

Unlike plastic, aluminum foil can handle high temperatures in ovens or grills without melting or releasing harmful chemicals. This makes it perfect for the food service industry.

Comparing Alloy Characteristics

Choosing between alloys like 1235, 8011, and 3003 depends on your mechanical requirements.

Understanding Tempers: O vs. H18

The “Temper” describes the hardness and flexibility of the aluminum.

Soft Temper (O State)

• Process: The foil is fully annealed (heated and cooled slowly).
• Feel: Very soft and easy to bend.
• Best for: Complex food wrappers, cable wrapping, and cigarette packaging.

Hard Temper (H18 State)

• Process: Cold-rolled without annealing.
• Feel: Stiff and springy.
• Best for: Battery current collectors and some types of rigid packaging.

Precision Manufacturing and Quality Control

Quality is not just a word; it is a measurable standard. Every roll of aluminum foil undergoes strict testing.

Pinhole Detection

For very thin foils (under 0.010mm), pinholes can be an issue. We use laser detection systems to ensure the barrier remains perfect.

Surface Finish

We offer different finishes based on your needs:

• Double Side Bright (DSB): Both sides are shiny.
• Single Side Bright (SSB): One side is shiny, the other is matte.

Edge Quality

Cleanly slit edges are essential. Burrs or nicks on the edge can cause the foil to tear when it is being unwound at high speeds in your factory.

Why Choose High Quality Aluminum Foil?

Using premium materials reduces waste in your production line. High-quality foil leads to:

• Fewer breaks: Durable foil handles machine tension better.
• Better adhesion: Clean surfaces allow glues and coatings to stick perfectly.
• Longer shelf life: A perfect barrier protects your final product for years.
• Environmental impact: Aluminum is 100% recyclable, helping you meet sustainability goals.

Whether you are in the energy sector, the food industry, or electronics, we provide the specific aluminum foil specifications you need to succeed.
