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. Se describe una bolsa que tiene al menos un compartimiento sellado que contiene una primer composición; al menos una pared del compartimiento sellado se fabrica a partir de una película soluble en agua que tiene cualquier grosor adecuado; la película soluble en agua comprende un polímero de PVOH de modo que cuando la película tiene un grosor de aproximadamente 76 micrones, la película se caracteriza por un índice de disolución de aproximadamente 620 a aproximadamente 920 o de aproximadamente 665 a aproximadamente 920 o de aproximadamente 710 a aproximadamente 920 y un índice de esfuerzo de aproximadamente 145 a aproximadamente 626 o de aproximadamente 155 a aproximadamente 480 o de aproximadamente 165 a aproximadamente 325.
