Title: METHOD FOR THE PRODUCTION OF A LAYER FOR COATING THE PLASTIC INNER SURFACE OF A RECEPTACLE, AND RECEPTACLE OBTAINED BY A METHOD OF SAID TYPE
Abstract:
The invention relates to a method for producing a barrier layer (13, 9) for coating the inner surface (12, 17) of a receptacle (10, 6) which is made at least in part of plastic and is used for holding products that are biocompatible for humans and/or animals; in said method, a solution is formed that contains at least one solvent, water, at least one organo-functional molecular precursor, and an acid as a catalyst, the complexed solution, which is undergoing hydrolysis and condensation, is applied to at least one portion of the inner surface of the receptacle, the applied solution is dried at a specific drying temperature below 100°C, and the receptacle is conveyed away and stored before being baked.
