PROBLEM TO BE SOLVED: To provide a method for producing a water-soluble embossed film which is high in blocking resistance and low in brightness and has a feeling of high grade and good pinhole resistance. SOLUTION: A water-soluble film, after being prepared on a drum or a belt having a high-grade-imaged pear-skin pattern, is passed between an embossing roll and a backup roll for an uneven pattern to be embossed with the uneven pattern, so that the pear-skin pattern the surface roughness (Ra) of which is 0.1-8μm, and the uneven pattern of 100 mesh or less the depth of which is 50-300μm are formed on the film. |
