High quality printed images are a necessity, especially on food packaging. Ink can’t bleed into the product, however, and that ink must bond securely to the packaging. Printed cups, such as for yoghurt or margarine, must be stacked together for transport before they are filled but ink transfers from one printed exterior to the interior of the next cup must be avoided at all cost.
Pretreatment with Openair® plasma can safely prevent this undesired effect. Thanks to plasma activation, bonding of printing inks to the food packaging is substantially improved. Inks will not rub off. The speed of subsequent flat or rotary screen printing can also be significantly increased.

Put Openair-Plasma® to the test with our rental and test systems.
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.
In addition to the Openair-Plasma Systems for surface treatment Plasmatreat GmbH also offers individual production cells with automated solutions to ensure seamless integration in the production lines. Plasma Treatment Units (PTU) are tailored to the customer's technical processes and are equipped with various operating options. Here Plasmatreat offers the solution of coordinated process automation combining efficient surface treatment and a perfectly coordinated handling of assemblies and components.
Plasmatreat plans to get more involved in the disinfection industry by providing solutions for disinfecting protective clothing during the current corona crisis.
