Abstract
A process for manufacturing packaging ( ) with good barrier properties against passage of water vapor and gases is such that recesses are shape-formed in a film-shaped material ( ) to act as containers ( ) to accommodate contents. After cutting the shape-formed film into individual units of packaging ( ), these are coated in vacuum with materials exhibiting the desired barrier properties. A device for carrying out the process comprises a shaping station ( ) for shape-forming the containers ( ) from the film-shaped material ( ), a cutting station ( ) for cutting the packaging ( ) out of the shape-formed, film-shaped material ( ), and a vacuum-coating station ( ) for coating the packaging ( ). The process and the device make it possible to manufacture e.g. light-transparent blister packs within a packaging line, whereby the good barrier properties against passage of water vapor and gases can be achieved using relatively cost-favorable starting materials.
