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 or each recess, and sealing the first sheet to the second sheet to form a continuous closed seal around the or each recess thereby closing the or each 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 or each package within a secondary pack. The secondary pack includes a moisture barrier to maintain the or each package within the secondary pack in a conditioned form.

La présente invention concerne un processus de production d'un emballage, qui comprend une composition contenue dans une enveloppe soluble dans l'eau fermée. Ce processus consiste à: mouler une première feuille d'un matériau soluble dans l'eau de façon à former au moins un enfoncement adapté pour contenir la composition, placer la composition dans le ou les enfoncements, placer une seconde feuille de matériau soluble dans l'eau en travers de cet ou de ces enfoncements, et coller la première feuille à la seconde de façon à former une fermeture continue autour de cet enfoncement ou de chacun de ces enfoncements, fermant ainsi le ou les emballages. Cet emballage ou chacun de ces emballages sont conditionnés dans un environnement hygrométrique relativement élevé durant une période précédant le conditionnement de cet emballage ou de chacun de ces emballages dans un second paquet, ou durant le conditionnement proprement dit. Ce second paquet comprend une étanchéité permettant de conserver le ou les emballages dans ce paquet dans sa forme conditionnée.
