The electrostatic adsorption of transparent thermal labels may be relatively serious, which mainly depends on a variety of factors, including environmental humidity, material characteristics, printing and labeling processes.


Electrostatic adsorption cause

1.Ambient humidity: The generation of static electricity is closely related to air humidity. In a dry environment, the surface resistance of the object increases, and it is easier to generate static electricity. Therefore, in the autumn and winter season or in an environment with low air humidity, the electrostatic adsorption problem of transparent thermal labels may be more prominent.

2.Material characteristics: The transparent heat-sensitive label material itself may have a certain insulation, which means that once static electricity is generated, the charge is not easy to dissipate quickly. In addition, the friction between the label and the packaging material and the affixed object is also easy to lead to the generation and accumulation of static electricity.

3.Printing and labeling process: In the printing process, the paper is stripped from the paper roll, and the charge transfer between the print head and the rubber roller, resulting in static electricity. Similarly, during the labeling process, the friction separation between the label and the backing paper and the object to be affixed may also cause static electricity.


The influence of electrostatic adsorption

1.Operation problems: Electrostatic adsorption may cause abnormal labels during transportation, die-cutting, and labeling, such as label adhesion, wrinkling, and foaming, affecting production efficiency and product quality.

2.Quality problems: Static electricity may absorb dust and impurities in the air to the surface of the label, causing defects such as pinholes and white dots in printed images and images, which reduces the appearance and readability of the label.

3.Safety problem: In extreme cases, electrostatic discharge may cause fire or electric shock, which threatens the production environment and personnel safety.


Solution

In order to reduce the electrostatic adsorption of transparent thermal labels, you can take the following measures:

1.Control the ambient humidity: Increase the humidity of the printing workshop and maintain the relative humidity between 50% and 65%, which helps to reduce the generation of static electricity.

2.Use antistatic materials: Select transparent heat-sensitive label materials with antistatic properties to reduce static electricity at the source.

3.Installing an electrostatic discharge device: Install an electrostatic discharge device, such as an ion-air electrostatic discharge device, on the printing and labeling device to eliminate static electricity in a timely manner.

4.Operation specifications: Ensure that operators wear ESD clothes and gloves to reduce static electricity generated by friction between the human body and devices and materials.

5.Regular equipment maintenance: Keep printing and labeling equipment clean and in good condition to reduce electrostatic problems caused by equipment wear and pollution.


In summary, the electrostatic adsorption of transparent thermal labels may be relatively serious, but by taking appropriate measures, you can effectively reduce the impact of this problem on production efficiency and product quality.
