Abstract
A process for producing a package comprising a composition contained within a closed water soluble envelope comprises the initial steps of moulding a first sheet of water soluble material to form at least one recess adapted to contain the composition, placing the composition in the at least one recess, placing a second sheet of water soluble material across the recess, and sealing the first sheet to the second sheet to form a continuous closed seal around the recess thereby closing the package. The or each closed package is conditioned in an environment of raised relative humidity for a period of time prior to or during the packaging of the package within a secondary pack. The secondary pack includes a moisture barrier to maintain the package within the secondary pack in a conditioned form.
