The invention relates to a composite laminate, especially a transdermal therapeutic system (TTS) that contains in at least one layer a component that is sensitive to moisture. Said system further comprises one layer that is spatially separate from said at least one moisture-sensitive layer and that is capable of absorbing moisture. The spatial separation can be achieved by means of a horizontal or vertical separation layer.
