Polyolefins such as PP and PE are often used in the medical industry for the manufacture of single-use products in order to benefit from the advantageous properties of the material.
Plastics such as PVC, PU, PC and others often need their adhesive properties to be optimized before further processing.
The surface properties of polyolefins such as PP, PE with their inherently very low surface energies make subsequent adhesive processes such as gluing and printing a challenge.
UV adhesives and UV printing inks in particular place high demands on the quality of the surface pretreatment.
Classic pretreatment processes such as priming or flame treatment have their disadvantages for example complex implementation and handling, high running costs for consumption and storage, high health and environmental requirements and difficult process control.
Plasma pretreatment at atmospheric pressure is a simple, inexpensive and controllable type of pretreatment. The so-called activation enables optimal adhesive forces and wettability.
In the medical industry there is also the advantage of the strong disinfecting / sterilizing effect of plasma treatment on treated surfaces.
- Simple and clean process through cost-efficient, environmentally friendly electrical plasma treatment
- Reliable reproducibility of the pretreatment, even with sensitive surfaces, due to the adjustable and controlled plasma discharge
- Full monitoring of all process-relevant parameters due to real-time monitoring with TIGRES SQI (System Quality Index)
