The present invention addresses the problem of providing: an edible film having high water solubility, flexibility, strength, adherability, and transparency; and a use thereof. This edible film 1 has a layered structure having a water-insoluble coating layer 3 on one surface of a water-soluble substrate layer 2. The substrate layer 2 is a water-soluble layer containing an alginate salt as a main component. The substrate layer 2 has a thickness of 10-50 [mu]m. The coating layer 3 is a water-insoluble layer containing shellac as the main component. The coating layer 3 has a thickness of 1-10 [mu]m. The edible film 1 is useful as a partition for foods.本發明之課題在於提供一種具備較高之水溶性、柔軟性、強度、密接性、及透明性之可食性膜及其用途。可食性膜1具有於水溶性之基材層2之一個面設置有水不溶性被覆層3之積層構造。基材層2係含有海藻酸鹽作為主成分之水溶性層。基材層2之厚度為10~50 μm。被覆層3係含有蟲膠作為主成分之水不溶性層。被覆層3之厚度為1~10 μm。可食性膜1作為食品用分隔材較為有用。
