At present, the use of paper bags is very wide, has been applied in many fields, we use it every day in life, but for the bag making machine in the production of warp edge how do we deal with it? Below we will introduce, and as the paper bag machine occupies a greater role in our lives, we will face more paper bag production equipment.
Let's first take a look at the reasons for the warping of paper bags in production:
1, the thickness of the production of paper bag material is inconsistent;
2, the heat sealing temperature is too high or the heat sealing time is too long;
3. In the longitudinal hot sealing tool part, the running track of the composite film is not straight;
4, the film in the composite material has poor heat resistance;
5, in the composite process, the tension matching control of the composite substrate is improper, resulting in residual stress after aging, especially when the thickness of the composite film is thin, such failures are more likely to occur.
If these problems occur, we can follow the following methods:
1, adjust the floating roller tension;
2, the selection of low-temperature heat sealing inner sealing substrate;
3. Adjust the heat sealing temperature to the appropriate temperature;
4, re-select the surface substrate film;
5, adjust the tension of each part of the composite processing equipment, and try to make the contraction rate of the two substrates of the composite equal.

These are some of the solutions we have summarized by using paper bag South equipment for many years, hoping to help you solve the problem.
