As a supplier of corona treatment pens, I often get asked about the frequency of these remarkable tools. In this blog, I'll delve into the concept of frequency in relation to corona treatment pens, exploring its significance, how it impacts the treatment process, and why it matters for your specific applications.
Understanding Corona Treatment
Before we discuss the frequency, let's briefly understand what corona treatment is. Corona treatment is a surface modification technique used to improve the adhesion properties of materials such as plastics, films, and papers. It works by exposing the surface of the material to a high - energy corona discharge. This discharge ionizes the air around the material, creating free radicals that react with the surface molecules. As a result, the surface energy of the material increases, allowing inks, coatings, and adhesives to bond more effectively.
What is Frequency in Corona Treatment Pens?
Frequency in the context of corona treatment pens refers to the rate at which the electrical pulses are generated to create the corona discharge. It is measured in Hertz (Hz). Different frequencies can have a significant impact on the effectiveness of the corona treatment.
Low - frequency corona treatment pens typically operate in the range of a few thousand Hertz. These pens are often used for materials that are more sensitive to high - energy treatment. For example, some thin films or delicate plastics may require a lower frequency to avoid damage to the material. The lower frequency allows for a more gentle treatment, gradually increasing the surface energy without causing excessive degradation of the material.
On the other hand, high - frequency corona treatment pens can operate at frequencies in the tens of thousands of Hertz or even higher. High - frequency treatment is more aggressive and can quickly increase the surface energy of the material. This is beneficial for materials that have a high surface tension and require a more intense treatment to achieve good adhesion. For instance, some high - density plastics or materials with a very smooth surface may need a high - frequency corona treatment to break down the surface and make it more receptive to inks and coatings.
Factors Affecting the Choice of Frequency
Several factors influence the choice of frequency for a corona treatment pen:
Material Type
Different materials have different surface properties and require different treatment intensities. As mentioned earlier, thin and delicate materials are better suited for low - frequency treatment, while more robust materials can handle high - frequency treatment. For example, polyethylene terephthalate (PET) films used in packaging may need a different frequency compared to polypropylene (PP) materials used in automotive parts.
Application Requirements
The end - use application also plays a crucial role in determining the frequency. If you are printing on a material, the type of ink and the quality of the print required will influence the frequency. For high - resolution printing, a more precise and consistent surface treatment may be needed, which could be achieved with a specific frequency. Similarly, if you are using an adhesive to bond two materials, the frequency of the corona treatment can affect the strength of the bond.
Line Speed
In industrial applications, the speed at which the material is moving through the treatment process is an important factor. Higher line speeds may require a higher frequency to ensure that the material is treated effectively as it passes through the corona discharge. If the frequency is too low, the treatment may not be sufficient, resulting in poor adhesion.

The Importance of Correct Frequency
Using the correct frequency for your corona treatment pen is crucial for several reasons. Firstly, it ensures that the surface energy of the material is increased to the optimal level for adhesion. If the frequency is too low, the surface treatment may be insufficient, and the ink, coating, or adhesive may not bond properly. This can lead to issues such as peeling, cracking, or poor print quality.
Secondly, using the right frequency helps to prevent damage to the material. High - frequency treatment can be too aggressive for some materials, causing them to become brittle or deformed. By selecting the appropriate frequency, you can ensure that the material remains intact while achieving the desired surface modification.
How to Determine the Right Frequency
Determining the right frequency for your corona treatment pen can be a bit of a trial - and - error process. However, there are some general guidelines you can follow.
- Consult the Material Manufacturer: The manufacturer of the material you are using may have specific recommendations regarding the frequency of corona treatment. They can provide valuable insights based on the material's properties and intended use.
- Conduct Tests: It's a good idea to conduct small - scale tests on sample materials using different frequencies. This will allow you to observe the effects of the treatment on the surface and determine the frequency that provides the best results.
