High speed in-line treatment of plastic webs for vacuum coating

摘要

Beside the layer quality a good adheson between coating and polymer substrate is a precondition for the manufacture of quality thin film products. Due to the inertness of most polymer surfaces an appropriate treatment of substrates prior deposition is necessary. Typical examples for the necessity of pretreatment are the deposition of barrer layers on BOPP film and the deposition of layer systems on organic hardocat for windown films.
