Abstract

It is often desirable to make packs, consisting of foils heat-sealed to one another, reclosable after opening and after the partial removal of the packaged product, in order to separate the remaining packaged product at least partially from the environment. For this purpose, there is provided, in addition to the heat-sealing region by means of which the upper and the lower foils are connected to one another, a reclosing region consisting of individual closing elements which, fitting into one another, are provided in the two foils. In the reclosing region, the foils are not connected materially to one another. On the contrary, spot-like closing elements which also allow a slight undercut are provided. They are shaped, without a male mould, in female moulds which are exposed to underpressure, whereas the other side of the foil is under overpressure. Shaping therefore takes place purely pneumatically. In this way, the shape of the closing elements can be given widely varying designs and can easily be adapted to the requirements of each individual pack. <IMAGE>
