PROBLEM TO BE SOLVED: To provide a storing box for a lap film which is equipped with an inserting blade capable of decreasing a friction with a hand or the like even when inserting resistance to the lap film is small when a notch is formed and which can advance propagation along a covering lid piece during cutting without decreasing a cut end face strength in the storing box in which the notch is formed by the inserting blade at one position of the lap film for food or the like, and which can be cut by propagation. SOLUTION: In order to decrease the friction with the hand or the like without spoiling the inserting workability to the lap film, both edge parts of the blade ridge is made to be a circular arc, and in order to suppress a circular arc-like propagation of the lap film, the notch shape 11 dividing the covering lid piece 5 and an unsealing piece 6 is made to be double perforations.
