2115244 9304120 PCTABS00020 The rate of disintegration in cold water of water soluble packaging films is improved by incorporating into a film forming polymer composition, to form a dry blend or aqueous dispersion, a substantially water insoluble cellulose material prepared from alkali metal salts of carboxy(lower alkyl) cellulose or hydroxy(lower alkyl) cellulose. The increased disintegration is achieved without loss of film stability and, in some cases, the film stability is improved.
