Method to avoid defective products in automatic packaging film production

1: Advancing glue (MST, KPT) surface concentration and coating amount are not easy to wet, easy to produce bubbles, especially in winter. The air bubbles on the ink can be removed by the advancing glue; 　　2: the composite temperature and pressure of the advancing composite film; 　　3: increase the pressure time of the composite roller and the lubrication roller, the film is fully preheated, reduce the composite speed, and choose a good wettability adhesive , Select ink accurately; 　　4: select high molecular weight, fast curing glue, increase the concentration of the glue, and make the glue dry and dry under the condition of higher oven temperature; 　　5: keep a certain temperature in the operating place; 　　6: adjust the drying of the glue Temperature; 　　7: the temperature of the advancing composite roller, reducing the composite angle (thick film, easy to produce bubbles when hard).　　 Label: Machine roll film
