Safety-closure or original-pack closure for the outlet dispensing openings in packaging in the form of a multi-layer composite. The multi-layer composite features a first and a second adhesive layer such that the two adhesive layers lie one against the other. The layers adhere to each other but do so without sticking together and can be separated from each other. In addition to the adhesive layers, the multi-layer composites usefully feature one or two substrate layers. Using such multi-layer composites it is possible for example to close plastic blister packs that cannot be opened simply by pushing the contents through the lid but instead require a safety layer to be removed via the two adhesive layers; or containers may be produced featuring an original pack closure and a permanent closure for closing the container again.
