ABSTRACT:
A water-soluble film made from a resin composition comprising (A) 100 parts by weight of an anionic group-modified polyvinyl alcohol having a viscosity of 10 to 35 mPa·s measured at 20° C. with respect to a 4% by weight aqueous solution thereof, an average degree of hydrolysis of 80.0 to 99.9% by mole and a rate of anionic group modification of 1 to 10% by mole, (B) 20 to 50 parts by weight of a plasticizer, (C) 2 to 30 parts by weight of a filler, and (D) 0.01 to 2.5 parts by weight of a surfactant. The water-soluble film has an excellent water solubility, and is not gelled or insolubilized even if chemicals containing a boric acid substance, particularly sodium perborate, are packaged therein or even if it is put in an aqueous solution of a boric acid substance, particularly sodium perborate.
