There will be many problems in the use of the three-side sealing bag making machine. In the process of use, we should learn to master the use of the machine through these problems, so that the machine can be used for a longer time. At the same time, we believe that in the process of use, you must have encountered these problems.

1. Problem 1: Bag warping occurs in the heat sealing of three-side sealing bag making machine. Reasons and solutions:

Reasons for heat sealing:

(1) the thickness of the composite film is inconsistent;

(2) the heat sealing temperature is too high or the heat sealing time is too long;

(3) in the longitudinal heat sealing part, the running track of the composite film is not straight;

(4) insufficient cooling;

(5) the curing time is not enough;

(6) The heat resistance of surface substrate film is poor;

(7) Improper tension matching control of the composite substrate in the composite process leads to residual stress after ripening and shaping, especially when the thickness of the composite film is thinner, such faults are more likely to occur.

Countermeasures adopted:

(1) Adjust the tension of the floating roller;

(2) choose the inner sealing base material with low temperature heat sealing;

(3) Adjust the heat sealing temperature to the appropriate temperature;
