Rotary Arm Stretch Wrapping Machine for Static Wrapping of High-Stacked Pallets

Higher Requirements for Wrapping High-Stacked Pallets
In many packaging environments, certain pallet loads are tall, top-heavy, or structurally unstable, making them unsuitable for turntable rotation. Forced rotation can cause load shifting or instability during wrapping, increasing safety risks. For such applications, a wrapping method that keeps the pallet stationary is a more appropriate solution.
Basic Working Principle of the Rotary Arm Wrapper
The rotary arm stretch wrapping machine wraps film by rotating an arm-mounted film carriage around a stationary pallet. During operation, the arm performs circular motion around the load while the film carriage moves vertically, ensuring continuous film coverage from bottom to top and forming a uniform external wrap.
Pre-Stretch Film Carriage for Enhanced Load Stability
The machine is typically equipped with a pre-stretch film carriage that stretches the film to a preset ratio before application. This maintains consistent film tension and allows the film to contract after application, improving load containment and overall stability. Wrapping parameters such as the number of wraps and reinforced zones can be adjusted according to pallet height and packaging requirements.
Structural Design for Multi-Pallet Compatibility
The rotary arm stretch wrapping machine is designed to accommodate different pallet sizes. Arm rotation radius and film carriage lift height can be configured based on site conditions. For pallets with varying heights, sensors automatically detect load dimensions, ensuring smooth wrapping and reducing manual intervention.
Application in Warehousing and Outbound Operations
This type of equipment is commonly installed at warehouse dispatch areas or production line endpoints for centralized pallet wrapping. Once wrapped, pallets are ready for forklift handling and truck loading, improving outbound process consistency and reducing uncertainties associated with manual operations.
By keeping the load stationary and rotating the wrapping mechanism, the rotary arm stretch wrapping machine provides a stable packaging solution for high-stacked pallets. In practical applications, it helps standardize pallet wrapping processes, ensuring consistent packaging quality and reliable external protection throughout warehousing and logistics operations.
