Process for applying alternating layers e.g. barrier layers onto a plastic bottle by chemical gas phase deposition comprises depositing an organic adhesion promoting layer on a substrate and applying an inorganic barrier layer

摘要

Process for applying alternating layers by chemical gas phase deposition comprises depositing an organic adhesion promoting layer on a substrate and applying an inorganic barrier layer. The coating time for applying the adhesion promoting layer is 0.05-4.0 seconds and for applying the barrier layer is 0.1-6.0 seconds. An Independent claim is also included for a composite material made from the substrate and the alternating layers.
