VIPER
Next-Generation Battery-Powered Strapping Tool
Viper is SIAT’s next-generation battery-powered strapping tool, designed for PP and PET straps in 9, 12, and 16 mm (3/8"–1/2"–5/8"). Its capacitive touchscreen offers intuitive control and real-time feedback, making strap tensioning, sealing, and cutting simple and fast.
Strapping is done manually by placing the strap around the package, while tensioning, sealing, and cutting are performed automatically at the touch of a button. The strap ends are joined with a friction welding process for secure and consistent seals.
Lightweight and perfectly balanced, Viper ensures operator visibility, reduced fatigue, and easy one-hand use in both horizontal and vertical applications. With its registered Italian design, it sets a new standard for ergonomic, efficient, and safe strapping.
➜ Suggested for logistics hubs, e-commerce, food & beverage, and manufacturing companies needing a fast, reliable, and user-friendly strapping solution.
