The invention relates to packaging (1) for storing at least two substances i n separate chambers, comprising: a first chamber (3) which contains a flowable first substance, (5) and a second chamber (7). The first chamber (3) and the second chamber (7) are respectively formed by liquid-tight sections of a bas e film (11) which are sealed together, and a cover film (13). The cover film (13) is a composite film comprising a first blocking film (21) made of a met al material and the base film (11) is a composite film comprising a second blocking film (29) made of a metal material. The metal material of the secon d blocking film (29) is softer than that of the first blocking film. The base film (11) and the cover film (13) are sealed to each other in such a way in an area connecting the first chamber (3) to the second chamber (7), that by applying external pressure on the first chamber (3), (a) the sealing connection between the films (11, 13) is selectively dissolved in the above- mentioned region (15), (b) a through-opening channel (25) is formed between the first and the second chambers, and (c) the first substance (5) can be transferred from the first chamber to the second chamber. |
