Self-supporting bag custom common problem analysis

Self-supporting bag custom common problem analysis.

1, thesealing temperature
In setting the heat sealing temperature factors to consider, it is the characteristics of heat sealing materials;2 it is to film thickness;3 is the number of hot heat sealing pressure and the size of the heat sealing area.In general, the same parts of the hot pressure is large, the number of heat sealing temperature can be appropriately set lower.
2, heat sealing pressure
Must be properly when heat sealing pressure can promote thermal cover adhesive materials.But if the pressure is too big, can make molten material extrusion, not only affect the flatness fault analysis and ruled out of the bag, can also affect the effect of heat sealing bag, reduce the heat sealing strength.

3, heat sealing time
Heat sealing time in addition to the associated with heat sealing temperature and heat sealing pressure, and the performance of heat sealing materials, heating mode and other related factors.Specific operation should be according to the different equipment and materials, adjusted during the actual trial.
4, heating mode
When heat sealing bag heat-sealing knife heating mode can be divided into two classes: unilateral heating and heating on both sides.Obviously, both sides heating mode than unilateral heating method is efficient and practical.
