@shoanlai: Folding and sealing the carton → tilting roller turning → corner sealing – a seamless I-shaped sealing process! The automatic folding and sealing machine completes the top and bottom "I"-shaped sealing, while the tilting roller allows the carton to automatically and smoothly reverse 90° without jamming. The corner sealing machine simultaneously seals and smooths the four corners. The three machines work together seamlessly, the entire line operates fully automatically without manual intervention, and the sealing effect is flat, standardized, and aesthetically pleasing.
