How to set the heat sealing temperature of the bottom seal bag making machine?
- Nov 24, 2018 -

The bottom seal bag making machine can produce bags of different specifications, which are widely used in the food and chemical industries. In the bag making process, a heat sealing temperature is required, and the bottom seal bag making machine is no exception. Its function is to heat the adhesive film layer to a more ideal viscous flow state.

 

When setting the heat sealing temperature for the bottom seal bag making machine, it is necessary to comprehensively consider the characteristics of the heat sealing material, the thickness of the film, the number of times of heat sealing and the size of the heat sealing area, and the like. If the number of hot pressing of the agreed part is increased, the temperature can be appropriately lowered. If the heat seal area is increased, the heat sealing temperature can be adjusted.

 

In the bag making process, the heat sealing strength is affected by the heat sealing temperature. The higher the heat sealing temperature, the heat sealing strength will increase, but at a certain temperature, the heat sealing strength will not change. If the heat sealing temperature is too high, the heat sealing material at the welded portion will be damaged, and the heat sealing strength of the sealing and the impact resistance of the bag will be lowered. Therefore, the heat sealing temperature is higher than the melting temperature of the heat sealing material, and the temperature should not be too high.
