Nowadays, the competition for packaging machinery is becoming increasingly fierce, and low-consumption, high-efficiency, multifunctional, intelligent and automated packaging equipment is increasingly favored by the industry. Labelling machines are playing an increasingly important role in the packaging market. No matter what kind of mechanical equipment will have problems of one kind or another after being used for a period of time, at this time, technicians must come to check and repair, and labeling produces bubbles. Is there a problem with the labeling machine? Like, what are the reasons for creating bubbles? Let's take a look together!

Dust on the surface of the bottle is not clean enough and can cause air bubbles. During the entire process of using the labeling machine equipment, if the surface of the entire bottle is not clean or dry enough, it should be marked in a variety of ways based on the shape on the surface of the bottle. When labeling, the conveyor belt should be tightened and stabilized. In this case, especially for flat plastic bottles, corresponding cleaning work should be done. Irrational selection of membrane materials will also lead to bubbles.

During the entire labeling process, labeling machines and equipment will see that all these machines and equipment are made of corresponding materials on the surfaces. If it is a relatively soft bottle, it is usually best to use many synthetic materials that have not yet been stretched PE or PVC from the entire surface of the machine and equipment. If it is a relatively hard bottle, it is best to use the surface materials of those batches.

If the speed of the labeling machine is not adjusted reasonably, there will be bubbles. In the specific application of labeling machines and equipment, the rotational speed of the entire labeling machine will be adjusted. This is completely inappropriate. During the entire labeling process of the entire labeling machine equipment, the operating speed of the bottle body is relative. It may be slightly faster than the label adjustment speed of the current label to effectively solve the appearance of bubbles, so it is best to eliminate static electricity before the labeling machine performs labeling work, so that the entire label can become particularly clean.
