The effect of heat sealing temperature of PVC bag making machine
In the bag making process, the PVC bag making machine needs a heat sealing temperature, and its function is to heat the adhesive film layer to a more ambiguous viscous flow condition. When selecting the heat sealing temperature, 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. If the number of hot pressing of the agreed part is increased, the temperature can be appropriately lowered. If the heat sealing area is increased, the heat sealing temperature can be adjusted.
