Hot melt adhesive coating machine to achieve excellent performance method (3).

Secondly, special attention should also be paid to the selection of air drying temperature. Grasp the air-drying temperature to bring excellent characteristics to the application of Hot melt adhesive coating machines. Too high or too low temperature will endanger the bonding color fastness of composite bags. When the sizing plate is dry, the hot temperature is too high or it is steamed at high temperature, which will carbonize the surface of the adhesive, and then destroy the bonding ability of the adhesive.  If the dry temperature is too low, the adhesive is not completely dry, the viscosity of the adhesive is weak, the composite type is not firm and after a period of time, the composite bag is easy to produce bubbles, destroying the composite quality of the product.
