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.
