What is the cause of the bubbles generated by the sticker labeling machine-industry news

The self-adhesive labeling machine is an automatic packaging machine that uses a self-adhesive roll of label paper. During the automatic bottle feeding process with a bottle unscrambler, the roll of label paper is continuously torn off and attached to the bottle body according to the required position.　　　　 One of the common problems when using the self-adhesive labeling machine is the bubble phenomenon. Sometimes it may be better to adjust it, but sometimes it will appear again after a while. So how can we solve this imagination?　　　　 There are many reasons for the blistering phenomenon, which are introduced below: 　　　　 1. For example, the surface of the bottle 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.　　　　2. If the speed of the 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.　　　　 3. 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 during labeling, so you should try to eliminate static electricity before using it.　　　　 4. If the base paper is not selected properly, 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.
