Water-soluble film having improved dissolution and stress properties, and packets made therefrom |
摘要 |
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. |

1. A water-soluble film having any suitable thickness, the water-soluble film comprising:
at least 50 wt. % of a water-soluble polyvinyl alcohol (PVOH) resin, the PVOH resin having an average viscosity in a range of about 13.5 cP to about 20 cP and a degree of hydrolysis in a range of about 84% to about 92%; and the film further having no more than 30 wt. % of a PVOH polymer having an average viscosity less than about 11 cP; the film further characterized by having a Dissolution Index in a range of about 620 to about 920 and a Stress Index in a range of about 145 to about 626 when the film has a thickness of about 76 microns, wherein the film is thermoformable. |
