For the plasma pretreatment of large-area workpieces, various plasma sources are available that operate under normal pressure conditions. All systems work according to the principle of barrier discharge on a treatment width of up to approx. 40 cm. The systems are particularly suitable for the plasma pretreatment of planar surfaces or web material. Materials such as plastic films, textiles, paper and wood are particularly suitable.
