[0002] With the development of food packaging technology, a variety of product packaging formats have emerged. For some dairy products, in order to ensure a tight package, the packaging type used is hexagonal packaging material (four layers stacked at the corners and two layers in the middle). During the heat sealing process of the automatic packaging machine, due to the different thicknesses, the heating is uneven. While the four layers are heated and sealed, the second layer is not warm enough. Conversely, while the second layer is sealed well, the fourth layer is burnt and deformed. Therefore, this packaging type cannot be processed by traditional automated packaging equipment and can only be packaged by manual pressure.
