1. Heat sealing temperature

The factors to consider when setting the heat sealing temperature of fruit juice bags are: firstly, the characteristics of the heat sealing data; The second is the thickness of the film; The third is the number of hot stamping times and the size of the hot sealing area. In general, when the same part is pressed more times, the heat sealing temperature can be set lower appropriately.

2. Heat sealing pressure

Proper pressure must be applied during heat sealing to promote the adhesion of the hot cover material. But if the pressure is too high, it will cause the molten data to be squeezed out, which not only affects the flatness analysis and troubleshooting of the juice bag, but also affects its heat sealing effect and reduces 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 function of the heat sealing data, heating method, and other factors. The specific operation should be adjusted during practical testing based on different equipment and materials.

4. Heating method

The heating methods of the heat sealing knife during the hot sealing of fruit juice bag making can be divided into two categories: single side heating and two end heating. Obviously, the two end heating method is more practical.
