Rotary Arm Stretch Wrapper with Top Sheet Dispenser: Ideal Solution for Heavy Loads and Moisture Protection

New Demands in Packaging Safety
In modern logistics, pallet packaging must not only secure loads but also ensure dust and moisture resistance. For companies handling heavy, tall, or high-frequency shipments, conventional wrappers often leave pallet tops exposed, risking moisture damage, dust accumulation, or transit losses. The rotary arm wrapper with top sheet was developed to solve this, combining side wrapping with top sealing for full coverage.

Features: Stationary Loads, Rotary Arm + Top Cover Protection
Operating on a “load stationary, arm rotating” principle, it’s ideal for oversized or unstable pallets.
Advantages include:

• Top sheet function: Automatically covers the pallet top before wrapping, protecting against dust and moisture.

• High efficiency: Completes wrapping + top sealing in just 2–3 minutes.

• Stable and safe: Pallets remain stationary, preventing tilting or collapse.

• Film-saving design: Pre-stretch ratio up to 250%, lowering film usage.

• Smart controls: PLC system for customizable layers, reinforcement cycles, and top sheet timing.

• Line integration: Easily connects to conveyors, palletizers, and other equipment for full automation.

Application: Comprehensive Protection Across Industries
Widely applied in chemicals, food, paper, building materials, electronics, and pharmaceuticals.

• Chemicals: Ton bags and drums stay protected in humid/rainy environments.

• Food & beverage: Ensures clean and secure packaging for supermarkets and exports.

• Paper & textiles: Prevents roll goods from absorbing moisture or deforming.

• Building materials: Protects stone, tiles, and boards from weather exposure during transport.

Case Study: Packaging Upgrade for a Paper Manufacturer
A paper mill exporting rolls previously used standard wrappers, leaving tops exposed and prone to water damage during container shipping. After adopting Dahong’s rotary arm wrapper with top sheet, every roll was fully covered. The system now wraps over 200 pallets daily, reducing complaints and labor costs. Management shared: “The top sheet function has eliminated moisture concerns during long-distance shipping, ensuring product quality.”

Smarter Protection, Safer Shipments
The rotary arm stretch wrapper with top sheet not only solves packaging efficiency for heavy loads but also adds moisture protection. By combining wrapping and covering in one process, it delivers compact, secure, and professional results. For companies demanding higher safety and reliability in transport, this solution is becoming indispensable—and as automation evolves, it will see wider adoption across industries.
