Challenges in Circular Product Packaging & the Need for Automation
Circular or coil-shaped products like steel coils, wire coils, tires, and rolled fabric are often heavy and difficult to stabilize. Manual wrapping is time-consuming and prone to inconsistency, leading to surface scratches, loose coil cores, and stacking issues. The ring wrapper, designed specifically for coil packaging, has become a key solution for enhancing packaging quality and shipping reliability.
Ring Structure: Dedicated Design for Full and Even Coverage
The core of the machine lies in its rotating ring platform and wrapping film carriage. Once the product is positioned, the film rotates around it to provide tight and uniform coverage without blind spots. The ring diameter, opening size, and speed can be customized based on product dimensions. Parameters are preset through a user-friendly HMI for one-touch automatic operation.
Automation: Pre-stretch Film & Constant Tension for Cost-Efficient Protection
Equipped with a pre-stretch film carriage, the film is stretched before wrapping to enhance strength and reduce consumption. PLC control enables precise adjustment of film tension, wrap count, and reinforcement layers at key positions such as the core and edges. This ensures consistent packaging performance while reducing both labor and material costs.
Application Case: Steel Coil Producer Boosts Efficiency & Quality
A steel coil processing plant suffered from low packaging speed and surface damages. After adopting a ring wrapping machines:
Packaging time dropped from 6–8 min to 1.5–2 min per coil
Surface damage rate noticeably decreased
Export acceptance quality improved significantly
Consumables and labor cost reduced month by month
Protect Every Surface to Ensure Safe Delivery
The ring wrapping machine replaces manual operation entirely—fast, reliable, and efficient. It supports multi-layer protection to resist dust, moisture, and handling impacts, improving product appearance, storage reliability, and transportation safety.
