What's the heat sealing temperature of the bag making machine?

In the process of bag-making, the bag-making machine needs a heat sealing temperature. Its function is to heat the adhesive film to an ideal viscous flow state. When choosing the heat sealing temperature, it is necessary to take into account the characteristics of the heat sealing material, the thickness of the film, the number of times of hot sealing and pressing, and the size of the heat sealing area. If the number of hot pressing at the agreed position increases, the temperature can be adjusted appropriately, and if the heat sealing area increases, the heat sealing temperature can be increased.
In the process of bag making, the heat sealing strength is affected by the heat sealing temperature. The higher the heat sealing temperature is, the higher the heat sealing strength will be. But when the upper limit of temperature is reached, the heat sealing strength will not change. If the heat sealing temperature is too high, it will damage the heat sealing material at the welding site, reduce the heat sealing strength of the seal and the impact resistance of the bag. Therefore, the heat sealing temperature should be higher than the melting temperature of the heat sealing material, and the temperature should not be too high.
