The invention relates to a packaging unit comprising a container and hygroscopic or humidity softenable film-like materials. For this purpose, said film-like materials are stacked in the container and a separating material which is chemically inert and physically stable with respect thereto is arranged at time between said film-like materials. Each time, said separating material is brought into contact with two film-like materials and does not adheres or adheres less strongly to at least one film-like material that to the other film-like material. Said invention makes it possible to develop a packaging unit provided with a container which guarantees a reliable individual withdrawal of the hygroscopic film-like materials.
