Top of Pallet Prone to Moisture and Dust? Rotary Arm Stretch Wrapping Machine with Top Sheet Provides Five-Sided Protection

Insufficient Top Protection Becomes a Common Packaging Risk
In warehousing and logistics, pallet loads are typically stabilized by stretch wrapping around the sides, leaving the top exposed. Over time, rain, dust, and ambient humidity can directly affect the goods. For industries such as food, chemicals, paper products, and building materials, moisture or contamination from the top can result in quality issues or even full pallet rework, increasing costs. The rotary arm stretch wrapping machine with top sheet is designed to address this weak point by adding a top covering structure to create more comprehensive protection.
Rotary Arm Design Keeps the Load Stationary
This machine adopts a rotary arm structure, keeping the pallet stationary while the arm and film carriage rotate around the load. Compared with turntable machines, it is better suited for large, tall, or less stable pallet loads, reducing the risk of load shifting during rotation. Smooth arm movement ensures continuous wrapping and consistent film tension, improving overall packaging quality.
Top Sheet Integration Achieves Five-Sided Wrapping
After completing side wrapping, the top sheet unit places a protective film over the top of the pallet load. The stretch film then secures the top sheet together with the side film, forming a unified structure. This five-sided wrapping method effectively blocks moisture and dust, making it ideal for storage and transportation environments with higher protection requirements.
Automated Control for Stable and Consistent Operation
The machine is typically equipped with a PLC control system, allowing users to set wrapping layers, top sheet placement, and operating speed based on load height and packaging needs. Automatic height detection enables synchronized film carriage movement, ensuring smooth operation and reducing manual intervention. In continuous or high-volume packaging environments, this automation helps maintain consistent packaging quality.
Wide Application Across Multiple Industries
Rotary arm stretch wrapping machines with top sheet are widely used in food and beverage, chemical materials, paper products, building materials, and electronics industries. They are suitable for both medium- and long-term storage as well as long-distance transportation. The machine can operate as a standalone unit or be integrated with conveyor systems to adapt to different production layouts.
Improved Packaging Standardization for Logistics Management
By combining side wrapping with top protection, pallet loads become more stable and visually uniform, simplifying stacking, loading, and warehouse management. Standardized packaging also reduces maintenance work caused by damaged outer packaging during transport.
By adding top protection to traditional stretch wrapping, the rotary arm stretch wrapping machine with top sheet delivers a more complete pallet packaging solution. Its stable operation and clear wrapping process make it a reliable choice for industries with high moisture and dust protection requirements.
