What Are The Causes Of Self-adhesive Label Bubbles. How To Solve The Label Bubbles
Nov 11, 2022| As we all know, self-adhesive label stickers have adhesive, in the labeling process is more likely to produce bubbles, which will directly affect the adhesive effect of the label stickers and externalities. The following will introduce two more commonly used label sticker problems and treatment methods, they are: transparent film class self-adhesive label stickers in the transparent bottle body will produce bubbles.
Factors that cause bubbles: the bottle surface is not flat, there are small depressions, or label stickers loose degree of matching the bottle will produce bubbles; labeling machine labeling method and bottle appearance design, or label labeling method is not appropriate, will make the label stickers within the residual air, resulting in bubbles.

Several common phenomena that generate bubbles:
Static effect
For film-based information self-adhesive stickers, static electricity will also make the sticker bubbles. Generally speaking, there are two reasons for the occurrence of static electricity: one is the dry climate, especially in northern China when using stickers in winter, often in the labeling process of static electricity. The second is the stickers and stickers and labeling
The machine will also occur when the conflict and touch the relevant parts of static electricity. In the active labeling machine for long labeling, the
Static electricity will form bubbles to affect the labeling role. To deal with the problem of static electricity can try the following methods. Reasonable control of the operating space temperature and humidity, the ideal temperature of 20-22 ℃, relative humidity of 50, perhaps able to use copper metal wire discharge.
One, transparent special self-adhesive labeling machine, the label using rubber scrapers.
Second, the use of materials matching the bottle material to print the bottle label.
Before labeling, check whether the surface of the bottle is flat. If it is not leveled, the mold for producing bottles should be leveled.
Second problem: Air bubbles are generated when applying a large number of paper labels to a vessel like an oil drum.
Causes of bubbles: The storage environment of the label sticker is too different from the temperature and humidity in which it is placed, resulting in bubbles due to the rapid adsorption of moisture after the label sticker is applied. Or due to the label sticker object surface is not flat or stained to produce blisters, resulting in label sticker is not firm, causing bubbles.
Solution
First, before labeling, the label stickers placed in the labeling environment for a period of time, so that it is balanced with the humidity of the environment.
Second, keep the surface of the labeling object dry and clean, labeling object in the labeling place with strong paste flat, paste firmly.
The above is the cause and solution of self-adhesive label foaming. If you want to know more, please contact our sticker expert.
