The change in the shape of the packaging machine causes a variety of bagging machines. Among them, the bag making, forming and sealing devices are different, and the points are as follows:
(1) Bag forming machine
The process of making bag-type bagging machine: bag forming---filling---sealing. Batch or continuous bag making is carried out using a flexible roll material, and then the filling, sealing and cutting processes are immediately performed, and the entire packaging process is completed on one machine. The variety of bag shapes determines the variety of bagging machines.
a. Bending forming filling and sealing machine
The bending forming device is a process of bending and deforming the flat packaging material into a roll shape by utilizing the inner and outer curved shapes of the former. These type of filling and sealing machines are vertical models that can be filled with various materials and are suitable for flat bags of various sizes.
b. Lapel forming machine bending forming filling and sealing machine and ring forming machine bending forming filling and sealing machine.
