In-mold labeling is a method that is mainly used for labeling blow molding and injection molded products. Many people may not know much about it. Here, let me explain to you the labeling process of in-mold labeling. . The printed film or paper in-mold labels (divided into front labels and back labels) are stacked in single sheets and placed in the label libraries on both sides of the in-mold labeling machine. As the bottle mold is opened, the front label and back label are sucked up by the robot. The printed side faces the mold wall and the adhesive side faces outwards and placed in the molds on both sides. The vacuum holes on the mold firmly adsorb the labels into the mold. . When the raw material of the plastic bottle is heated and hangs down like a hose, the mold with the label quickly closes, and air is blown into the hose to make it close to the wall of the mold. This is the blow molding process. At this time, the temperature in the entire mold is still relatively high, and the label solid adhesive close to the prototype of the bottle begins to melt and combine with the plastic bottle. Therefore, when the mold is opened again, the plastic bottle is formed, and the label It becomes part of the bottle.
