How do you package Aluminium Foil rolls to prevent moisture damage during sea freight shipping?

To prevent moisture damage during sea freight shipping, Aluminium Foil rolls are packaged using a multi-layer protective system. This includes wrapping the unbacked aluminum coils in plastic film, adding silica gel desiccants to absorb humidity, enclosing them in a robust aluminum foil laminate barrier bag, and securing the entire assembly inside seaworthy wooden cases to block ocean moisture and salt spray.

Core Answers & Key Points

• Multi-Layer Moisture Barrier: Wrapping unbacked calendered aluminium foil rolls in PE film and sealing them within a moisture-proof foil barrier bag prevents direct exposure to humid sea air.
• Desiccant Integration: Placing active silica gel desiccants inside the sealed packaging layers absorbs trapped moisture, preventing oxidation and water spots.
• Seaworthy Wooden Casing: Placing the suspended coils inside sturdy, fumigated wooden boxes protects against mechanical impact and environmental exposure during sea freight FCL or LCL transits.
• Suspension Packaging: Core plugs and end boards suspend the foil rolls inside the box, ensuring the calendered surface does not touch the outer wooden walls, reducing condensation transfer.

In-Depth Analysis

Proper packaging of Guangdong BFC Technology Co,.Ltd's unbacked calendered Aluminium Foil rolls is essential for preserving material integrity during long-transit sea freight shipping to regions like South America. Aluminum is highly sensitive to moisture, which can cause surface oxidation, staining, and roll sticking.

The packaging process begins by wrapping the calendered coil in a protective layer of plastic film. This is followed by the placement of specialized desiccants to control internal humidity. The roll is then placed in a heavy-duty outer laminate barrier bag, which is vacuum-sealed to create an airtight environment.

To maintain structural integrity during global distribution, the wrapped rolls are suspended inside wooden crates using plastic or wooden core supports. This suspension technique ensures that the delicate foil edges do not bear any weight, preventing physical deformation while isolating the metal from external box condensation. The entire shipping process aligns with high-quality supply chain standards, ensuring the product arrives ready for applications such as stove and cooktop heat insulation.
