Edible water-soluble film

A water soluble film, consisting of a water soluble mixture of

• a water soluble resin comprising polyvinyl alcohol, a modified polyvinyl alcohol, or a combination thereof, wherein the polyvinyl alcohol or modified polyvinyl alcohol is present in an amount in a range of about 35 to about 90 wt. %, based on the total weight of the film,
• a compatibilizing agent selected from carboxymethyl cellulose (CMC), hydroxypropylated starch, and a combination thereof, a sugar alcohol plasticizer that is a solid at room temperature selected from the group consisting of isomalt, maltitol, sorbitol, xylitol, adonitol, and a combination thereof, and,
• optionally one or more excipients selected from the group consisting of a plasticizer that is a liquid at room temperature, a surfactant, an antiblocking agent, and an internal release agent,
• wherein the water soluble film is substantially transparent according to having an opacity of 37% or less for a 2.0 mm film, after storing for 30 days after film formation,
• wherein the sugar alcohol plasticizer that is a solid at room temperature has a heat of fusion of 247 J/g or less and a concentration of 5 to 35 phr, and when the heat of fusion of a sugar alcohol plasticizer that is a solid at room temperature is greater than 192J/g then its concentration is 20 phr or less;
• and
• wherein the water soluble polyvinyl alcohol or modified polyvinyl alcohol component of the film is characterized by a weight average molecular weight in a range of about 55,000 to about 80,000 g/mol.
