Abstract
A film easily soluble in cold water comprises a water-soluble copolymer composed of 6 to 40 mol % of an allyl ester moiety and 94 to 60 mol % of a vinyl ester moiety and having a degree of sponification of not less than 65 mol %. The film is easily soluble in cold water and such solubility in cold water is not lowered even if it comes into contact with either alkaline or acidic materials and it can suitably used as wrapping material for packages which are directly thrown into water together with packed materials.
