Wet labeling glass is usually not a problem because the surface of glass is polar and wettable with water. But if the glass container has been coated with a polymer coat, targeted pretreatment is required to get the casein glue that is typically used to bond.
The RD1010 Openair® plasma jets, which can be integrated inline, activate the surface to increase the wettability of the coated glass, with low temperature impact.
Self-stick labels with the no-label look are used for sophisticated designs. Plasma pretreatment achieves both micro-cleaning (plasma cleaning) and targeted increase in surface tension. This way, bubble-free application of these labels is greatly simplified by using Openair® Plasma.

Determining surface tension with dyne inks now
Plasmatreat constantly faces shifting demands as a result of new ideas, regulations, and standards. Customers are increasingly approaching the company with unique and innovative project requests. Consequently, the capacities of the technology and research center will now be expanded to include a class-6 cleanroom.
Plasmatreat supports digitized manufacturing with its Plasma Control Unit (PCU) and makes numerous controls, regulation, and monitoring functions available to ensure consistently high surface-treatment quality and reproducibility.
VOCs occur when solvents and solvent-containing products are used, and they are harmful to the environment. Nevertheless, manufacturing in many industries still involves pre-treating surfaces with primers, bonding agents or other chemicals that release VOCs. With its Openair-Plasma process, Plasmatreat offers an environmentally friendly alternative.
