Solution of edge warping of paper bag machine in operation

When using the paper bag machine,what should we do when the paper bag machine warps during operation?How did this happen?How to solve it?

1.The thickness of paper bag materials is not consistent.

Solution:adjust the tension of floating roller.

2.Too high heat sealing temperature or too long heat sealing time lead to the damage and wrinkle of paper bag materials.

Solution:adjust the heat seal temperature to the normal temperature.

3.In the longitudinal heat sealing section,the running track of the composite film is not straight.

Solution:choose the inner sealing base material with low temperature heat sealing property.

4.The film in the composite has poor heat resistance.

Solution:re select the surface substrate film.

5.In the process of composite,the tension matching of composite substrate is not well controlled,which leads to residual stress after curing,especially when the thickness of composite film is thin.

Solution:adjust the tension of each part of the composite processing equipment to make the shrinkage ratio of the two composite substrates equal as far as possible.
