Steel wire coils are susceptible to damage from handling, moisture, and contaminants during transport and storage. Secure, high-quality packaging is crucial to:

• Maintain product integrity and prevent damage (e.g., deformation, corrosion).
• Ensure customer satisfaction by delivering coils in optimal condition.
• Uphold the manufacturer's reputation for quality.
• Facilitate safe and efficient handling throughout the supply chain.

1.2. Traditional Manual Packaging Methods

Historically, packaging steel wire coils involved multiple manual steps:

• Moving heavy coils to the packaging area.
• Manually applying wrapping materials (like stretch film, VCI paper, or woven belts).
• Securing the packaging using manual strapping tools.
• Labeling and preparing coils for shipment.
  This approach is inherently labor-intensive and prone to variability.

2. The Inherent Challenges of Manual Steel Coil Packaging

Manual packaging processes, while sometimes necessary for highly custom or low-volume tasks, present several significant drawbacks in typical production environments:
