Beschreibung
Zusammenfassung:	Disclosed is a pouch having at least one sealed compartment containing a first composition. At least one wall of the at least one sealed compartment is made from a water- soluble film having any suitable thickness. The water-soluble film comprises PVOH polymer such that when the film has a thickness of about 76 microns the film is characterized by a Dissolution Index of about 620 to about 920, or of about 665 to about 920, or about 710 to about 920; and a Stress Index of about 145 to about 626, or about 155 to about 480, or about 165 to about 325. La présente invention concerne une poche ayant au moins un compartiment scellé contenant une première composition. Au moins une paroi de l'au moins un compartiment scellé est fabriquée à partir d'un film hydrosoluble ayant une épaisseur adaptée quelconque. Le film hydrosoluble comprend un polymère PVOH de sorte que, lorsque le film a une épaisseur d'environ 76 microns, le film est caractérisé par un indice de dissolution d'environ 620 à environ 920, ou d'environ 665 à environ 920, ou d'environ 710 à environ 920 ; et un indice de contrainte d'environ 145 à environ 626, ou d'environ 155 à environ 480, ou d'environ 165 à environ 325.
