E-commerce Semi-auto Case Sealer

Equipment Overview

The e-commerce semi-automatic carton sealing machine is custom-designed for small express and e-commerce cartons. The operator folds the top and bottom flaps of the carton flat, the carton is fed into the machine, and dual-side belts automatically convey it while the upper and lower tape heads simultaneously apply tape to complete single-strip (I-shaped) sealing. The machine uses manual handwheel lifting to adjust the width, height and flap range; it has a compact, small structure and is easy to move, suitable for sealing mixed express cartons of multiple specifications. It can be used as a standalone unit or combined with a production line as a downstream sealing process.
