Structural Design and On-Site Performance of the Wrapping-and-Strapping Integrated Machine in Pallet Packaging

A Combined Workstation Integrating Wrapping and Strapping
In typical palletized packaging, stretch wrapping and strapping are separated into two workstations, requiring pallet transfer between machines. This creates unnecessary movement, extended cycle times, and inconsistent quality. To solve this, the integrated machine merges a pre-stretch wrapping unit with a pallet-through strapping system, allowing both processes to be completed at the same location. It is ideal for factories that require stable output, high pallet integrity, and efficient workflow coordination.

Unified Structure Combining Wrapping and Strapping
The system consists of a powered pre-stretch film carriage, pallet wrapper, pallet-penetrating strapping module, automatic film clamping and cutting unit, photoelectric height detection, and conveyor-line control. After the pallet enters the workstation, the photo sensor detects the height and triggers the wrapping process using preset pre-stretch ratios and reinforcement layers.
Once wrapping is complete, the strapping mechanism extends horizontally beneath the pallet, forming a closed loop around the pallet and load. Completing both processes at the same station eliminates pallet transfers, shortens cycle time, improves packaging uniformity, and simplifies automated line layout.

Adaptable to Various Pallet Types and Industry Applications
Cartons: Wrapping stabilizes the outer surface, while strapping secures the entire stacked structure.
Bags: Film adhesion and strapping pressure minimize deformation and slipping during transport.
Chemical industry: Heavy drums or bulk containers benefit from reinforced stability during forklift movement.
Building materials and panels: Mixed or irregular loads remain stable without repeated transfers between machines.

Enhanced Compatibility with Automated Packaging Lines
The integrated machine connects seamlessly with palletizers, roller conveyors, chain conveyors, barcode scanning, weighing systems, and automatic labeling units. After palletizing, the system automatically initiates the wrapping + strapping sequence. This reduces manual intervention and ensures consistent cycle time across multi-shift operations. Centralized packaging improves uniformity, shortens pallet-routing paths, and helps maintain a clean and organized packaging area.

Application Case
A building materials factory handling bagged powder products previously used separate wrapping and strapping machines. During transfers, the film sometimes loosened or shifted. After deploying the integrated machine, both processes are completed in one station, avoiding mid-process disturbances. Optimized film pre-stretch and strapping force significantly improved pallet stability, resulting in clearer workflow, smoother pallet flow, and more standardized warehouse stacking.

The wrapping–strapping integrated machine enables multiple fastening operations to be completed at a single station, reducing labor, improving consistency, and supporting automated workflows. It is compatible with different pallet styles and can integrate into advanced packaging lines to deliver standardized, reliable pallet outputs.
