Automatic labeling machine labeling is always a method of preventing bubbles

Presumably most manufacturers will encounter the problem of labeling machine failure. One of the most common problems when using a fully automatic labeling machine is the bubble phenomenon. Sometimes it may be fine to adjust it, but some This phenomenon will appear again after a while. So how can we solve this phenomenon? As the saying goes, knowing yourself and knowing the enemy can survive all battles. Therefore, if you want to cure the labeling bubble problem of the automatic labeling machine, the most important thing is to find the root of the problem. Knowing the reason will naturally solve all the problems. There are many reasons for foaming, such as the bottle surface is not clean and flat. Bottles should be washed and dried first, and according to the shape of the surface of the bottle during the labeling process, especially flat plastic bottles, the labeler should clamp and fix it with a conveyor belt. There is no basis for the bottle material, and the choice of suitable film material is also a reason. The soft bottle body should be made of polyethylene, polyvinyl chloride, unstretched polypropylene, polyethylene, polypropylene and other synthetic materials; the rigid bottle body should be made of PET, PS and other materials. If the speed of the automatic labeling machine is not adjusted properly, it will also cause bubbling. Especially when labeling, the speed of the bottle body should be slightly faster than the speed of the label, so as to avoid bubbles. Static electricity is also one of the reasons that affect the blistering. If there is static electricity, the label will bend and not firm, so that it is easy to bubble up when labeling, so you should try to eliminate static electricity before using it. The relationship between the labeling speed, blade strength, angle and distance should be adjusted when the soft bottle is labelled. In addition, if the base paper is not properly selected, blistering will also occur. The manufacturer recommends that users choose a smooth base paper, such as PE base paper, so that after the label is applied, the glue surface will be smooth, moist and smooth.
