Abstract
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.
Claims6
A packaging unit comprising a container and film-like materials that are hygroscopic or soften under the influence of moisture, characterized in that:
- the film-like materials (30) are arranged in the container (10) in the form of a stack,
- interposed between any two film-like materials (30), there is a separating material (40) that is physically stable and chemically inert to these film-like materials (30),
- each separating material (40) is in contact with the two film-like materials (30) and
- the separating material (40) does not adhere to at least one of these two film-like materials (30) or it adheres to it less strongly than it does to the other film-like material (30);
- characterized in that the individual separating material (40) is a PET film with an anti-adhesive coating (47) at least on one side;
- and
- the separating material (40) carries—on the side opposite to that with the anti-adhesive coating (47)—a coating (46) that is in adhesive contact with the film-like material (30).
