Abstract (en)
[origin: WO02092439A2] Thermoformed water-soluble packages are known, but some suffer from "shrink-back", which prevents the volume of a formed cavity being fully utilised at the filling stage. To overcome this the present invention proposes a packaging system wherein each individual container (25) of a multiplicity of such containers all joined together in a group side by side in a web comprises an inner water-soluble or dispersible encapsulate (25) enclosed wholly within and thermoformed simultaneously with a protective external water-insoluble casing (19, 11), and each of the encapsulate and the casing is, separately, in the form of a thermoformed hollow body and a lid (23) and is made from two films (15, 12 and 19, 11) bound together by one common seal, so that each encapsulate is in contact only with the inner wall of its casing.
