摘要：
Disclosed are plasticized water soluble films having favorable cold water solubility wet handling and thermoforming characteristics and which can include a PVOH resin made up of blend of two or more PVOH polymers each having a monomodal molecular weight distribution and the PVOH resin characterized by a viscosity in a range of about 13.5 cP to about 20 cP (or a corresponding weight average molecular weight) a degree of hydrolysis of about 84% to about 92% a polydispersity index value in a range of about 1 to about 5 a residual water content of about 4 wt.% to about 10 wt.% and a Resin Selection Index value in a range of 0.255 to 0.315 methods of making the films compositions including PVOH resins for making the films and pouch and packet articles made from the films.
