Product Overview

This dual side labeling machine is engineered for automated front back labeling operations across food, pharmaceutical, beverage, cosmetic, and industrial packaging lines. The two side labeler features a closed-loop motor with precision German photoelectric sensors for repeatable label placement on both front and back surfaces. Built with stainless steel construction and high-grade aluminum alloy, the machine integrates seamlessly into production line integration scenarios via conveyor belt systems.

Keypack Intelligent (kunbupack) front and back labeling machine offers non-standard customization with modular assembly design. The system supports PLC control with large touchscreen HMI for recipe management and real-time monitoring. Compact design enables flexible factory layout while maintaining high-volume throughput for small batch production and multi-SKU operations. The front and back label applicator includes bottle orientation correction, bottle separation, labeling, label smoothing, and counting mechanisms for complete automation.
