Reasons for the problem of edge warping in the operation of paper bag machines
Release time:
2022-01-28
The first major reason is that the heat sealing temperature is too high, too hot or the heat sealing time is too long, resulting in damage and wrinkling of paper bag materials
Solution: Adjust the heat sealing temperature to normal temperature;
The second major reason is that in the longitudinal heat sealing knife part, the running track of the composite film is not straight
Solution: Select an inner sealing substrate with low temperature heat sealing property;
The third reason is that the film in the composite material has poor heat resistance;
Solution: Re-select the surface substrate film;
The fourth reason is that the tension matching of the composite substrate during the composite process is improperly controlled, resulting in residual stress after curing and setting, especially when the composite film thickness is thin, such failures are more likely to occur
Solution: adjust the tension of each part of the composite processing equipment, as far as possible to make the two kinds of composite substrate shrinkage rate is equal.
The fifth reason: the thickness of the production paper bag material is inconsistent;
Solution: adjust the tension of the floating roller;
