Since the automatic packaging roll film is more convenient in the packaging process, many companies now choose to use the automatic packaging roll film as the main packaging material, but when using the automatic packaging roll film, it is inevitable that they will encounter quality problems more or less. Analyze how to avoid the occurrence of defective products in the production of automatic packaging roll film. Ways to avoid defective products in automatic packaging roll film production: 1: The concentration and coating amount of the advancing glue (MST, KPT) surface is not easy to wet, and it is easy to generate air bubbles, especially in winter. The air bubbles on the ink can be removed by advancing glue; 2: Advance the lamination temperature and lamination pressure of the lamination film; 3: Increase the pressurization time of the lamination roller and lubricate the roller, fully preheat the film, reduce the lamination speed, and choose a glue with good wettability , accurately select the ink; 4: Choose high molecular weight, fast-curing glue, increase the concentration of the glue, and make the glue dry under the condition of high temperature in the oven; 5: Keep a certain temperature in the operating place; 6: Adjust the drying of the glue Temperature; 7: Advance the temperature of the composite roll to reduce the composite angle (the film is thick and easy to produce bubbles when it is hard).
