Due to AutomaticPackaging Coil FilmIn the packaging process of convenience, so now many enterprises have chosen automatic packaging film as the main packaging materials to use, but in the use of the process will find automatic packaging film quality problems, the following let's analyze the automatic packaging film in the production process of bad products solution
Solution: 1, forward glue concentration and coating amount, (MST, KPT) surface is not easy to moist, easy to produce angry bubbles, especially in winter. Ink bubbles, with the use of forward glue method to remove; 2, forward composite film composite temperature and composite pressure, 3, add composite roller pressure paste moment and the use of lubrication roller, film preheating abundant, drop composite speed, selection of good wetting glue and accurate selection of ink; 4, the selection of high molecular weight, curing rapid glue, forward glue concentration , forward oven temperature abundant make glue boring; 5, the operation of the place to maintain a certain temperature, 6, adjust the adhesive boring temperature, 7, forward composite roller temperature, reduce the composite angle (thick film, hard when the production of Angry Bubbles).
Composite film appearance bad Bubble 1, thin film wetting 2, ink surface bump and foaming, 3, ink surface on the amount of glue coating less; 4, the film additives (lubricants, antistatic agent) by glue soaked seepage; 5, winter temperature is low, binder on the film and ink handling, wetting adhesion is not good; 6, boring temperature is too high, The foaming or epidermal crust of the adhesive occurs, and the inside is not dried; 7. The composite roller film is encased into the air.
