2024-04-01

H-type carton sealing machine and I-type carton sealing machine are both automated equipment used for carton sealing. Their main difference lies in the different sealing methods.


The sealing method of the H-type carton sealing machine is to first seal the upper and lower sides of the carton, and then seal the four sides of the carton to form an "H" shape. The H-type carton sealing machine can effectively prevent cartons from loosening during transportation and improve the sealing and firmness of cartons.


  1. H-type carton sealing machine are usually highly flexible and adaptable and suitable for packaging goods of various shapes and sizes. 

  2. It works by placing the box on the machine, which automatically folds and closes the lid, and then seals the box with tape or hot melt glue. 

  3. The H-type carton sealing machine is suitable for small and medium-sized packaging production lines because it can handle boxes of different sizes and is easy to adjust. 

  4. H-type carton sealing machines usually have high sealing speeds and can meet a certain level of production needs.





The sealing method of the I-type carton sealing machine is to only seal the upper and lower sides of the carton, while the four sides of the carton are not sealed. The I-type carton sealing machine seals boxes faster, but the sealing and firmness of the cartons are not as good as the H-type carton sealing machine.


  1. The I-type carton sealing machine adopts a more simplified design. Its working principle is to feed the box into the machine from one port, and then the machine automatically folds and seals the box lid to complete the carton sealing process.

  2. Focusing on sealing speed and stability, Type I carton sealing machine are usually suitable for large-scale production lines and can complete the sealing task quickly and efficiently.

  3. The I-type carton sealing machine can greatly improve production efficiency and reduce packaging costs.
