Bad effect of improper corona treatment on thin films
After printing, the ink color of plastic film must be firm, and the composite film must have a certain strength, otherwise, it will lose its use value. Improper surface polarization treatment will have a bad effect on the quality of the film and even cause waste products.
When the surface polarization treatment strength is not enough, the ink color is firm or the composite strength cannot meet the requirements.
Excessive surface polarization treatment can also cause the following problems:
The surface of the film is punctured to make the film wrinkled;
1. The barrier property of the film was reduced, which made the preservation performance of the film worse;
2. The adhesion between the layers of the film, especially the adhesion inside the blown barrel material, is not easy to separate;
3. The welding performance of the film is reduced and the welding fastness of the film is decreased.
