Each fully automatic block bottom bag making machine is equipped with a Mitsubishi electrical control system to provide stability and easy operation. Compared with sheet fed paper bag making machines, the block bottom bag making machine is more environmentally friendly and economically affordable because it can create high-quality bag from thin paper based on flexo printing. These machines operate with high performance and energy efficiency that is sustainable for future endeavors.

Feeding unit

  • The roll paper fixed on the air expanding mandrel can be fed by swing arm which is equipped with lifting hydraulic system. With an alarm function, the feeding unit will sound alarm when there is no paper feeding. Improved surface smoothness of the paper during the feeding is achieved due to the web guide and uniform tension control. Paper rolls can be easily changed by pressing a button.

Bag Forming unit

  • Material in the form of a tube is fed from the unwinder. The machine will form paper with patches and side glue into the tube; and cut into separate pieces based on the settings. The tube is then sealed and a cut is made below the seal, so that a tube with the bottom closed is formed.

Bag collecting unit

  • Compress the bags and outlet the bags. Number of paper bags can be processed and presented by an automatic collection and counting system.
