To provide a housing box of a wrapping film for food packaging which is suitable to improve the easiness in pulling out of the wrapping film.
The edge of a pull-out port 4 side of a top plate 302, is formed into a V-shape. Such a V-shaped part 303 is provided in such a manner that it may tilt from both ends of the top plate 302 in the longitudinal direction to the center. The V-shaped part 303 comes into contact with a wrapping film 2, but if a force to rotate in the opposite direction from the pulling out direction is applied to the wrapping film 2 under this state, the wrapping film 2 bites into the center of the V-shaped part 303 by the force, and a kind of wedge like effect generates there, and the wrapping film 2 is prevented from dropping from the top plate 302 by the effect.
