PROBLEM TO BE SOLVED: To provide a rice-processed food packaging material capable of restraining sheet-like food, which is housed between outer and inner sheets, from getting wet.SOLUTION: In an inner sheet, an overlap area, which is formed by making ends of a pair of sheet pieces overlap each other, is provided in an area between both ends in the other direction. An interval between both ends of the overlap area in the other direction is longer in a central-side area than in areas on both the end sides of the inner sheet in one direction.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】外シートと内シートとの間に収容されたシート状食品が湿気ってしまうのを抑制することができる米飯加工食品用包装材を提供することを課題とする。【解決手段】前記内シートは、他方向における両端部間の領域に、一対のシート片の端部同士が重なり合って形成された重合領域を備えており、他方向における重合領域の両端部間の間隔は、一方向における内シートの両端側の領域よりも中央側の領域の方が広くなるように構成されることを特徴とする。【選択図】図2
