Rotary Arm Stretch Wrapper — High-Speed Continuous Operation, Safer for Heavy Loads

In heavy-load and high-volume packaging scenarios such as chemicals, building materials, and machinery, traditional turntable wrappers often struggle with load shifting or instability. The rotary arm stretch wrapper, designed for safety and speed, eliminates these issues and delivers superior performance for demanding production lines.
Stationary load, rotating arm — safer and more stable
Unlike turntable models, the load remains stationary while the wrapping arm rotates. This prevents tilting or shifting, especially for tall or top-heavy goods.
The servo-driven rotary arm ensures smooth acceleration and deceleration, maintaining constant film tension without wrinkles or breaks. Even for loads over two tons, it delivers consistent, secure wrapping at high speed.
High-speed continuous operation
Powered by industrial-grade servo motors and a PLC intelligent control system, the rotary arm wrapper supports 24/7 operation.
It completes up to 50 pallets/hour and performs automatic film feeding, cutting, smoothing, and resetting — all without stopping.
The system can also integrate into automated conveyor lines, enabling seamless in-line operation for high-output factories.
Power pre-stretch — lower cost, better protection
With a film elongation rate exceeding 250%, the power pre-stretch system reduces material usage by 15%–30%. The film is evenly applied, ensuring tight, aesthetic wrapping that resists moisture, dust, and vibration during long-distance transport — achieving both cost savings and performance.
Versatile applications across industries
This machine suits a wide range of sectors including building materials, chemicals, food & beverage, machinery, and logistics.
It automatically detects pallet height and adjusts the number of wrapping layers for precise coverage. Optional top-sheet dispensers provide added dust and moisture protection for long-distance or outdoor storage needs.
Case study: Building materials manufacturer
A Shandong-based building materials company previously used semi-automatic wrapping, achieving only 15 pallets/hour with inconsistent stability. After adopting the rotary arm stretch wrapper, output rose to 40+ pallets/hour, while labor demand fell by two-thirds.
The packaging became tighter and more consistent, with transport shifting reduced by 80%, significantly lowering logistics costs.
The rotary arm stretch wrapper stands out for its speed, safety, and efficiency — making it the ideal solution for heavy-duty and high-frequency packaging operations. By combining automation, stability, and material savings, it helps enterprises achieve smarter, more reliable logistics and production-line integration.
