摘要

1. A bag containing a first hermetically sealed compartment containing the first composition, wherein said first hermetically sealed compartment contains at least one wall that includes a water-soluble film, and said water-soluble film contains: at least 50 wt.% Water-soluble polyvinyl alcohol resin (PVA), wherein said PVA resin has an average viscosity in the range of from about 13.5 cps to about 20 cps, and the degree of hydrolysis in the range of from about 84% to about 92%, is indicated the first PVA polymer contains a mixture of the first and second PVA polymers, said first PVA polymer having a viscosity in the range of about 8 cPs to about 40 cPs, and said second PVA polymer has a viscosity in the range of about 10 cPs to about 40 cPs, and said viscosity said first PVA polymer is less than said viscosity of said second PVA polymer; and wherein said film comprises no more than 30 wt% PVA polymer having a viscosity of less than about 11 cPs. 2. The bag according to claim 1, wherein said film is characterized by a resin withdrawal index value in the range of from about 0.255 to about 0.315.3. A pouch according to claim 1, wherein said film further has a resistance value of a drop of water of at least about 60%. The bag of claim 1, wherein said film further has a test residue value after washing of at least about 4.5.5. The bag according to claim 1, wherein said film further has a residual moisture content of at least about 4 wt.%. Bag according to claim 1, in
