- 1. A container system comprising:
a closeable container having walls that define an interior space; at least one pouch in the interior space, the pouch comprising a water-soluble film and a household care composition at least partially enclosed in a compartment by the water soluble film, the household care composition comprising from about 0.1% to about 10%, by weight of the household care composition, of perfume, and from about 1% to about 50%, by weight of the household care composition, of an organic solvent; the film comprising at least about 50 wt % of a polyvinyl alcohol (PVOH) resin blend, a first PVOH polymer present from about 65 wt % to about 90 wt % of the total PVOH polymers in the film, the first PVOH polymer comprises a first anionic monomeric unit, a vinyl alcohol monomer unit, and optionally a vinyl acetate unit, the PVOH resin blend further comprising a second PVOH polymer present from about 10 wt % to about 35 wt %, the second PVOH comprises a PVOH homopolymer consisting essentially of a vinyl alcohol monomer unit and optionally a vinyl acetate unit; and wherein the household care composition does not include (i), (ii), (iii), or (iv):
(i) about 15% to about 60% of Quadrant I, Quadrant II, and Quadrant III perfume ingredients;
(ii) about 2% to about 15% Quadrant I perfume ingredients;
(iii) about 2% to about 15% Quadrant I perfume ingredients, 2.5% to 25% Quadrant II perfume ingredients, 10% to 50% Quadrant III perfume ingredients, and 40% to 85% Quadrant IV perfume ingredients
(iv) perfume encapsulated in a core/shell encapsulate.

- 33. A container system comprising:
a closeable container having walls that define an interior space; at least one pouch in the interior space, the pouch comprising a water-soluble film and a household care composition at least partially enclosed in a compartment by the water soluble film, the household care composition comprising from about 0.1% to about 10%, by weight of the household care composition, of perfume, and from about 1% to about 50%, by weight of the household care composition, of an organic solvent; the film comprising at least 50 wt % of a polyvinyl alcohol (PVOH) resin blend, the PVOH resin blend comprising a first PVOH polymer that comprises a first anionic monomeric unit, a vinyl alcohol monomer unit, and optionally a vinyl acetate unit, the PVOH resin blend further comprising a second PVOH polymer that comprises a second anionic monomeric unit, a vinyl alcohol monomer unit, and optionally a vinyl acetate unit; wherein the household care composition does not include (i), (ii), (iii), or (iv):
(i) about 15% to about 60% of Quadrant I, Quadrant II, and Quadrant III perfume ingredients;
(ii) about 2% to about 15% Quadrant I perfume ingredients;
(iii) about 2% to about 15% Quadrant I perfume ingredients, 2.5% to 25% Quadrant II perfume ingredients, 10% to 50% Quadrant III perfume ingredients, and 40% to 85% Quadrant IV perfume ingredients;
(iv) perfume encapsulated in a core/shell encapsulate.

a closeable container having walls that define an interior space; at least one pouch in the interior space, the pouch comprising a water-soluble film and a non-household care composition at least partially enclosed in a compartment by the water-soluble film, the non-household care composition comprising from about 0.1% to about 10%, by weight of the non-household care composition, of perfume, and from about 1% to about 50%, by weight of the non-household care composition, of an organic solvent;
the film comprising a polyvinyl alcohol (PVOH) resin blend,
the PVOH resin blend comprising a first PVOH polymer that comprises a first anionic monomeric unit, a vinyl alcohol monomer unit, and optionally a vinyl acetate unit, the PVOH resin blend further comprising a second PVOH polymer selected from the group consisting of:
a) a PVOH polymer that comprises a second anionic monomeric unit, a vinyl alcohol monomer unit, and optionally a vinyl acetate unit, or b) a PVOH homopolymer consisting essentially of a vinyl alcohol monomer unit and optionally a vinyl acetate unit.
