Abstract

A procedure for the manufacture of a cold water soluble film, 0.5-10 mils (0.0127-0.254 mm) thick, consisting of melt extruding a composition consisting essentially of 5-20 parts by weight of a polyethylene glycol with an average molecular weight of 325-550 about 100 parts by weight of a low molecular weight polyvinyl alcohol that is hydrolyzed at 85-90% and has a viscosity of 3-10 cps measured in 4% aqueous solution at 20ºC .
