Workflow of H Shape Case Sealer
The carton goes into the carton sealing machine with the conveyor belt, DES-F5050 seals the top and bottom of the carton with packing tape.
In the second stage, the carton is pushed into the DES-F7050S by a 90 degrees turning device, and the machine taps the four outer edges of the carton.
In the video, the carton is folded manually.
If you want to save labor, do it automatically by machine.
You can use KEEPTOP’s case erector, with a speed of up to 18 cases/min.
