The factors that need to be considered when setting the heat sealing temperature of the aluminum spout pouch are: one is the characteristics of the heat sealing material; the other is the thickness of the film; the third is the number of times of heat sealing and pressing and the size of the heat sealing area.
1. Heat sealing temperature
The factors that need to be considered when setting the heat sealing temperature of the aluminum spout pouch are: one is the characteristics of the heat sealing material; the other is the thickness of the film; the third is the number of times of heat sealing and pressing and the size of the heat sealing area. Under normal circumstances, when there are many times of ironing on the same part, the heat sealing temperature can be appropriately set lower.
2. Heat sealing pressure
Adequate pressure must be applied when the aluminum spout pouch is heat sealed to facilitate the bonding of the heat seal material. However, if the pressure is too large, the molten material will be extruded, which will not only affect the flatness fault analysis and elimination of the bag, but also affect the heat sealing effect of the bag and reduce the heat sealing strength.
3. Heat sealing time
In addition to the heat sealing temperature and heat sealing pressure, the heat sealing time of the aluminum spout pouch is also related to the performance of the heat sealing material and the heating method. The specific operation should be adjusted according to different equipment and materials during the actual test machine.
4. Heating method
The heating method of the heat sealing knife during the heat sealing of the aluminum spout pouch can be divided into two categories: one-side heating and two-side heating. Obviously, the two-sided heating method is more efficient and practical than the single-sided heating method.
