摘要：
The invention relates to the lacquering of polar film substrates with a coating system consisting of several components, the single application of material resulting in a multilayer structure of the lacquer coat. The coating system is preferably aqueous and free from organohalogen and results in an improved barrier action of the films against water vapor.
