Plasma pretreatment of bottle and glass closures prior to labeling was one of the earliest standard applications of the Openair® Plasma process.
To ensure the integrity of a package’s contents, a tamper-evident closure or tax label is required. These seals must be glued from the main label (on glass) up over the closure (metal or plastic).
The closures that are used are produced in a cold forming process that uses lubricants that can leave remnants residues on the surface of the closure that require micro-cleaning prior to adhesiongluing. After Openair® plasma Plasma pretreatment, the entire labeling of both the main label and the seal label can be accomplished with the same adhesive.

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.
