2-3 Common Packaging Formats and Applications

2-4 Balancing Aluminum Foil Films and Medical Waste Recycling

• While pharmaceutical aluminum foil packaging ensures strong barrier protection, it also faces challenges in medical waste recycling.
• Performance: The aluminum layer must be sufficiently dense to effectively prevent moisture and oxidation.
• Recycling and Reuse: By adopting separable material designs and developing mono-material aluminum films, recycling efficiency can be improved.
• Practical Case: Several global pharmaceutical companies have implemented detachable aluminum–plastic structures to reduce the environmental impact of medical waste.

III. Anti-Static Metal Bags — The Key to Protecting Sensitive Electronic Components from ESD

 

3-1 Potential Risks of Static Electricity and Electromagnetic Interference

For precision electronic components, even a tiny electrostatic discharge (ESD) can cause malfunction or irreversible damage.What seems like a harmless “static spark” in daily life can destroy sensitive semiconductor devices.

3-2 Differences Between Anti-Static Bags and Vacuum Packaging Bags

• Anti-Static Metal Bags: Prevent static buildup and discharge; ideal for electronic components, semiconductors, and optical devices.
• Vacuum Packaging Bags: Remove air to reduce oxidation and mold growth; commonly used for food and certain medical consumables.
• Selection Principle: For ESD and EMI protection → 選choose anti-static bags.；For extended storage life → choose vacuum bags.

3-3 Key Functional Features

• Static Control: Surface resistance ranges from 10⁸ to 10¹¹ Ωmeeting multiple ESD protection levels.
• EMI Shielding: Reduces electromagnetic interference and ensures signal stability.
• Cleanroom Production: Manufactured in a Class 10,000 cleanroom to minimize particle contamination.

3-4 Formosa Flexible Packaging Corp’s Protection Logic

Formosa Flexible Packaging Corp designs its anti-static metal bags as “static isolation chambers.”Based on the component’s sensitivity, transport mode, and storage conditions, the shielding structure and surface resistance are precisely configured.

• Highly sensitive components (e.g., wafers): Dual-shield structures are recommended.
• Barcode readability required: Metal coating thickness can be adjusted, or transparent windows can be added.

3-5 Typical Application Scenarios

• Semiconductor wafers and IC substrates: Prevent ESD damage during production and testing.
• Consumer electronic motherboards: Reduce vibration and ESD risk during global shipping.
• Optical elements and polarizing plates: Prevent EMI interference to ensure imaging quality.

3-6 Applications in Aerospace and Defense Industries

Electronic systems in aerospace and defense equipment—such as flight control computers, radar modules, and communication units—are extremely sensitive to ESD and EMI.

• High stability requirements: Any damage can jeopardize flight safety or mission performance.
• Specialized design: Military-grade anti-static bags feature superior shielding and weather resistance.
• Safety certification: Must comply with MIL-STD and other military testing standards to ensure protection under extreme environments.

IV. Other Applications of Aluminum Foil Film — A Versatile Solution Across Industries

 

4-1 Applications in Communication and Industrial Fields

• Mylar aluminum foil is widely used as shielding layers for wires and cables, effectively blocking high-frequency electromagnetic interference (EMI).
• t is ideal for telecommunication equipment and precision instrument manufacturing, ensuring stable and interference-free signal transmission.

4-2Aluminum Foil Films in Art and Cultural Heritage Preservation

With its light-blocking, moisture-resistant, and anti-oxidation properties, aluminum foil film is highly suitable for long-term preservation of artworks and artifacts.

• Light Protection: Blocks UV and visible light to prevent pigment fading.
• Humidity and Temperature Control: Maintains stable storage conditions to prevent deformation of paper, textiles, or wood.
• Anti-Oxidation: Slows down the oxidation process of metal artifacts, extending their preservation lifespan.

4-3 Material Recommendations and Customization

• For Ultra-High Barrier Needs: Multi-layer aluminum foil structures are recommended.
• For Puncture Resistance: Use reinforced foil and composite film structures.
• For Special Applications: Thickness, coating, and printing can be tailored to specific industry requirements.
