What are the control details of the bag-making machine?

In the process of bag making machine needs a thermal sealing temperature, reasonable thermal sealing temperature is helpful for manufacturing, its role is to heat the adhesive film layer to a relatively ideal adhesive flow state.When selecting the thermal sealing temperature, the demand is based on the characteristics of the thermal sealing material, the thickness of the film, the number of hot sealing pressure, and the size of the thermal sealing area.If the number of pressing times of the agreed part is added, the temperature can be appropriately lowered, and if the hot sealing area increases, the high heat sealing temperature can be adjusted.

Here, let's take PVC plastic for example, PVC plastic is a non-crystalline polymer, with no fixed melting point, so there is only a melting temperature scale, that is, a temperature region between the solid phase and the liquid phase, when heated to this temperature scale, the film will enter the melting state.The upper and lower deviations of the temperature scale represent the differentiation and sticky flow temperatures of PVC.The magnitude of the difference between them is the key to determining the difficulty of thermal sealing
