Water-soluble packets

A water soluble pouch comprising a sealed compartment, the pouch comprising

• a first wall comprising a water soluble film comprising a water soluble resin;
• and a second wall comprising a water soluble film comprising a water soluble resin;
• the first wall film being sealed to the second wall film;
• the first wall film being characterized by
• a dissolution time of 300 seconds or less in water at a temperature of 20° C. for a first wall film having a thickness of about 76 micron in accordance with MonoSol Test Method MSTM-205;
• the water soluble resin of the first wall film having a 4% solution viscosity at 20° C. in a range of 14.5 cP to 25 cP;
• and
• a pouch strength of at least 200 N as measured by the first wall film sealed and tested according to the Pouch Strength Test;
• and
• the second wall film being characterized by:
• a dissolution time of 300 seconds or less in water at a temperature of 20° C. for a second wall film having a thickness of about 76 micron in accordance with MonoSol Test Method MSTM-205;
• the water soluble resin of the second film having a 4% solution viscosity at 20° C. in a range of 12 cP to 14.5 cP;
• and
• a tackiness value of at least 1500 g/s for a second film tested according to the Tackiness PA Test
• wherein the water soluble resin of the first wall film comprises a blend of a polyvinyl alcohol homopolymer and a polyvinyl alcohol copolymer comprising an anionic monomer unit;
• wherein the blend in the water soluble resin of the first wall film comprises from about 30 to 70 weight percent of the polyvinyl alcohol copolymer comprising an anionic monomer unit and from 30 to 70 weight percent of the polyvinyl alcohol homopolymer, based on the total weight of polyvinyl alcohol in the film;
• wherein the first wall film is characterized by a pouch strength of less than 2000 N as measured by the first wall film sealed and tested according to the Pouch Strength Test;
• wherein the water soluble resin of the second wall film comprises a blend of a polyvinyl alcohol homopolymer and a polyvinyl alcohol copolymer comprising an anionic monomer unit;
• and
• wherein the pouch has a pouch strength of at least 200 N as measured by the Pouch Strength Test.
