US 2010/0075077 A1 · CONTAINER HAVING IMPROVED EASE OF DISCHARGE PRODUCT RESIDUE, AND METHOD FOR THE PRODUCTION THEREOF

Abstract

In order to improve the emptying of residual contents from containers, such as pharmaceutical packaging, the invention provides corresponding substrates with a hydrophobic coating. Provided for this purpose is a composite material which comprises a substrate and a coating deposited on it, which forms at least a part of the surface of the coated substrate, with the coating having a compound containing the elements C, O, and H, with further elements, apart from Si, C, H, having a content of less than 10 at %, preferably less than 5 at %, characterized in that this compound has a composition SiOxCyHz, in which x is at most 1.2.
