You know the vacuum packaging hair is what reason cause it?

At present, the vacuum packing bag because its anti-static, oxygen insulation, shielding, moistureproof, window function and the characteristics of the excellent heat sealing and favored by the majority of the masses. Vacuum packaging application range is very wide also, but people if they found that when the vacuum food packaging use after a period of time, can appear the wrinkling, this will undoubtedly bring many inconvenience to use. Today small make up take you to understand what are the cause of the vacuum packaging will wrinkle. We think, in general, vacuum food packaging is in a period of time later they wrinkle may be caused by the following nine factors: 1, base material thickness is not uniform, bao hou differ too much. Solution: exchange quality qualified film. 2, base material roll deflection. Solution: adjust the orientation of the film, make its deflection does not occur in the process of transmission. 3, excess glue quantity may lack, interlayer sliding occurs; Uneven coating will also cause the occurrence of buckling. Solution: adjust the amount of glue, and uniform coating. 4 not fully dry, adhesives, residual solvent is too much, stick relay is small, the two kinds of base material before and after the composite displacement. Solution: adjust the technical parameters, the adhesive can be fully drab, reduce residual solvents. 5, composite film winding directly, without enough cooling or cooling high temperature soft composite membrane wrinkle easily. Solution: composite membrane should be after sufficient cooling before winding. 6, composite pressure Settings. Solution: adjust the composite pressure to the appropriate value. 7, tension control, put, winding tension not harmonious, don't match. Solution: regulate volume and winding tension, make each part of the tension match 8, the guide roller is not parallel to each other. Solution: adjust the guide roller parallelism. 9, the guide roller surface is not clean, stick with foreign body, or guide roller surface is not flat, there are potholes, his word, bruising, etc. Solution: guide roller clean or replace the new guide roller. Nine big reason for the above said, we also put forward the corresponding solutions. Believe that everyone in the production as long as strict attention to the above factors, try to avoid, can avoid the vacuum food packaging bags in the use of the prominent wrinkle.
