Understanding the B200: An Online Pallet Strapping and Wrapping System

Ensuring palletized goods remain stable and protected during transit and storage is a critical challenge in logistics and manufacturing. An effective solution is the integration of strapping and wrapping processes into a single, automated system. This guide explores the functionality and benefits of an online pallet strapping and wrapping machine, specifically referencing the B200 model as an example of such systems.

1. What is an Online Pallet Strapping and Wrapping Machine?

An online pallet strapping and wrapping machine is an automated packaging system designed to be integrated directly into a production or packaging line (hence "online"). It sequentially applies both straps and stretch wrap to pallet loads without manual intervention. This dual-action approach significantly enhances load security and protection compared to using only one method.

Key components typically include:

• Infeed/Outfeed Conveyor System: Transports pallets into and out of the machine.
• Strapping Unit: Applies vertical or horizontal straps around the load.
• Wrapping Unit: Dispenses stretch film around the pallet load.
• Control System: Manages the sequence, tension, and other parameters.

2. The Automated Packaging Process Explained

The operation follows a precise, automated sequence:

1. Pallet Entry: The loaded pallet travels via the integrated conveyor system and stops at the designated strapping position.
2. Strapping Application: The strapping unit applies a pre-determined number of straps (typically Polypropylene (PP) or Polyester (PET)) around the pallet load. The primary purpose is to unitize the load, prevent shifting of layers, and provide initial stabilization. Strap tension is carefully controlled to secure the load without causing damage.
3. Transfer to Wrapping: The conveyor moves the strapped pallet to the wrapping station.
4. Stretch Wrapping: The wrapping unit, often a turntable or rotary arm system, applies layers of stretch film around the pallet and load. This film provides containment, protects against dust, moisture, and potential tampering, and adds further stability, especially for irregularly shaped loads. Film tension and overlap are adjustable parameters.
5. Pallet Exit: Once wrapping is complete, the secured pallet is conveyed out of the machine, ready for dispatch or storage.
   

   

   3. Key Benefits of Integrated Strapping and Wrapping

Combining these two processes in one automated machine offers several advantages:

• Enhanced Load Stability: Strapping provides rigidity and unitization, while wrapping offers containment and protection, resulting in superior overall load security.
• Improved Product Protection: The stretch film shields goods from environmental factors like dust and moisture, and minor impacts during handling.
• Increased Throughput: Automation significantly speeds up the end-of-line packaging process compared to manual or semi-automatic methods.
• Reduced Labor Costs: Frees up personnel from manual strapping and wrapping tasks.
• Optimized Material Usage: Systems can be fine-tuned to use the optimal amount of strap and film for specific load requirements, potentially reducing waste.
• Consistent Packaging Quality: Automation ensures every pallet is strapped and wrapped to the same specifications, improving reliability.

4. B200 System Features and Capabilities

While specific configurations may vary, online systems like the B200 typically offer:

• Inline Integration: Designed to seamlessly connect with existing conveyor lines.
• Strapping Unit:
  • Accommodates standard strap materials (e.g., PP, PET).
  • Adjustable strap tension control.
  • Configurable number and position of straps.
• Wrapping Unit:
  • Utilizes LLDPE stretch film.
  • Adjustable film tension and pre-stretch capabilities (improves film yield).
  • Controllable number of top and bottom wraps, and carriage speed.
• Conveyor System: Powered roller or chain conveyors matched to line speed and pallet type.
• Optional Enhancements:
  • Top Sheet Dispenser: Automatically applies a sheet of film or plastic over the top of the load before wrapping for enhanced dust and water protection.
  • Automatic Corner Applicator: Places protective cardboard or plastic corners before strapping to prevent strap damage to vulnerable edges.
    

    

    5. Material and Parameter Customization

The effectiveness of the online pallet strapping and wrapping machine relies on tailoring the process to the specific load:

• Strapping Material Selection:
  • Polypropylene (PP): Suitable for light to medium-duty loads.
  • Polyester (PET): Offers higher tensile strength and retained tension, ideal for heavier or settling loads.
• Wrapping Film Specification:
  • LLDPE Stretch Film: Available in various thicknesses (gauge or micron) and formulations.
• Adjustable Parameters:
  • Strap tension.
  • Number and placement of straps.
  • Film tension and pre-stretch ratio.
  • Number of top/bottom wraps.
  • Wrapping pattern/overlap.

6. Common Applications and Industries

Automated combination systems are invaluable in high-volume environments across various sectors:

• Warehousing and Distribution Centers: Preparing diverse pallet loads for shipment.
• Manufacturing: Securing finished goods (e.g., food and beverage, consumer goods, building materials, electronics).
• Logistics and Third-Party Logistics (3PL): Ensuring safe transport of client goods.
• Agriculture: Palletizing bagged seeds, fertilizers, or produce.

7. Implementation Considerations

Integrating such a system requires planning:

• Line Integration: Ensuring compatibility with existing conveyor speeds and controls.
• Footprint: Allocating sufficient physical space for the machine.
• Maintenance: Scheduling routine checks and preventative maintenance.
• Operator Training: Equipping staff to operate and monitor the system effectively.

8. Conclusion

An online pallet strapping and wrapping machine represents a significant step forward in automated end-of-line packaging. By combining the strengths of both strapping and stretch wrapping into a single, efficient process, systems like the B200 provide enhanced load security, superior product protection, and increased operational throughput. Proper configuration and material selection ensure that palletized goods are optimally prepared for the rigors of transportation and storage in today's demanding supply chains.
