1. Heat sealing temperature

The factors to be considered when setting the heat sealing temperature of the aluminum spout pouch material are: 1. The characteristics of the heat sealing material; 2. The thickness of the film; 3. The number of heat sealing and heat pressing and the size of the heat sealing area. Generally speaking, when the same part is hot pressed multiple times, the heat sealing temperature can be appropriately reduced. Self-supporting nozzle

2. Heat sealing pressure

Proper pressure must be applied during the heat sealing process of the aluminum spout pouch material to facilitate the bonding of the heat shield material. However, if the pressure is too high, the molten material will be extruded, which will not only affect the flatness of the bag, fault analysis and elimination, but also affect the heat sealing effect of the bag and reduce the heat sealing strength.

3. Heat sealing time

The heat sealing time is not only related to the heat sealing temperature and pressure, but also to the performance of the heat sealing material, the heating method and other factors. The specific operation should be adjusted according to different equipment and materials during actual debugging.

4. Heating mode

The heating method of the heat sealing knife in the heat sealing process of the aluminum spout pouch material can be divided into two types: single-sided heating and double-sided heating. Obviously, heating on both sides is more efficient and practical than heating on one side.
