How does the low-temperature plasma cleaning system solve the printing and bonding problems of HDPE film?

How does the low-temperature plasma cleaning system solve the printing and bonding problems of HDPE film:
Due to the poor printing and dyeing, wetting, and adhesion properties of the HDPE film itself, and poor compatibility with other polymer materials, the activation and etching effects of the low-temperature plasma cleaning system can improve the surface of the HDPE film. Let me introduce to you the specific role of plasma activation and etching.

 the low-temperature plasma cleaning system

The activation of the low-temperature plasma cleaning system improves the hydrophilic properties of the HDPE membrane:
The low-temperature plasma cleaning system can open the CC and CH on the surface of the HDPE film. After the generated free radicals come into contact with nitrogen, oxygen, and water vapor, a large number of polar groups, such as oxygen, nitrogen, etc., are generated on the surface of the film. The number of groups directly affects the hydrophilic properties of the membrane surface. Therefore, after introducing a large number of polar groups, the hydrophilicity of the HDPE membrane is greatly improved. At the same time, due to the introduction of polar groups, the content of C element on the surface of the HDPE membrane decreases. , The mass fraction of O and N elements rises.
Etching of the surface of the HDPE film by the low-temperature plasma cleaning system:
The HDPE film is etched by the low-temperature plasma cleaning system, which can make the smoother surface uneven and form a groove shape, thereby increasing the surface friction resistance of the HDPE film, which is conducive to the improvement of the hydrophilic performance.
