摘要：
A water soluble film useful in unit dose chemical packaging is disclosed. The film may include: a water soluble saccharide and a polyvinyl alcohol copolymer consisting essentially of: (a) from 80 to 99 mole percent of vinyl alcohol and vinyl ester monomer； and (b) from 1 to 20 mole percent of a pyrrolidone comonomer. Such compositions may be used to provide a water soluble film simultaneously satisfying requirements in regard to water solubility biodegradability and physical properties even when used for packaging of harsh oxidizing chemicals.
