PROBLEM TO BE SOLVED: To provide a water-insoluble laminated edible film solving the problem of lack in water resistance of a conventional laminated edible film.SOLUTION: The water-insoluble laminated edible film has the following structure: an edible film formed by laminating two sheets of edible film and insoluble to water, is a laminated film which is formed by laminating a water-soluble cation film made of a cation material, and a water-soluble anion film made of anion material, wherein the cation material and the anion material react to each other between the water-soluble cation film and the water-soluble anion film, and the laminated film is insoluble to water.COPYRIGHT: (C)2010,JPO&INPIT【課題】耐水性の乏しい従来の積層可食性フィルムの課題を解決する。【解決手段】二枚の可食性フィルムが積層されて成る水に対して不溶性の可食フィルムが、カチオン性材料から成る水溶性カチオン性フィルムとアニオン性材料から成る水溶性アニオン性フィルムとが積層されて成る積層フィルムであって、前記水溶性カチオン性フィルムと水溶性アニオン性フィルムとの層間で、前記カチオン性材料とアニオン性材料とが反応して、前記積層フィルムが水に対して不溶性であることを特徴とする。【選択図】なし
