Cosmetic products are often difficult to label because they are provided with a surface made of polyolefins or lacquers which make labeling difficult or even impossible. Often, special white fields are provided that must be marked in order to achieve sufficient adhesion.
In order to be able to print independently, a plasma pretreatment is recommended. The plasma activation of the surface enables adhesion without having to provide white areas on the products.
Cosmetic products are often varnished for a good surface finish and feel. To ensure that the paint adheres well to the surface, the containers are treated 360 ° in front of the painting station. This ensures complete adhesion over the entire length of the product.
Plasma pretreatment is a simple, inexpensive and controllable type of pretreatment.
The plasma activates the surface and increases its wettability, so that paints, lacquer and ink wet well on the intended adhesive surface. Furthermore, the pretreatment creates an active surface that enables significantly higher adhesive forces.
