Why do sticker labels stick to plastic products?

Today, Xiaobian will take you to understand why the self-adhesive label will stick to plastic products!

In fact, our self-adhesive labels will stick to plastic products mainly in the following aspects:

The first reason: the adhesive sizing is not uniform

General self-adhesive label is composed of printing layer, adhesive and base paper, we can also according to the production process, the self-adhesive label coating, surface material, adhesive, silicone layer, base paper, back printing or back printing six parts together. If our self-adhesive label in the sizing process, uneven sizing process technical defects occur, it will cause foaming.

The second reason: the pressure of the labeling machine is not enough

The main components of the automatic labeling machine are usually unwinding wheel, buffer wheel, guide roller, drive roller, unwinding wheel, stripping plate and press wheel. The self-marking chain means that the driving shaft of the self-marking machine starts after the sensor on the self-marking machine sends out the data signal. Since the drum label is tensioned during assembly, when the bottom paper is closely attached to the stripping board to change the operating base, the self-adhesive label is forced to separate the bottom paper because its own sheet material is inevitably firm; At this time, the strip is located at the lower part of the self-adhesive label, and under the immersion of the press wheel, the label of the separation is evenly and neatly attached to the object. After labeling, the sensor below the drum label outputs data signals to prevent operation, the drive shaft is stationary, and the labeling process is completed.

The third reason: electrostatic effect

Static electricity can also make the label relative to the film material self-adhesive label foam.

In general, there are two factors in the formation of static electricity: one is caused by dry weather conditions, especially when self-adhesive labels are used in the cold winter in northern China, static electricity is often generated in the label link. Secondly, static electricity is also generated between the drip plastic self-adhesive label and the label and when the parts related to the label contact or friction with the automatic labeling machine.
