A container for packaging, comprising a container body for storing a wrap film wound in roll shape, a cover body rotatably arranged contiguously with the rear wall of the container body, and a V−shaped saw blade cutter fitted to the tip edge part of the front wall of the cover body, wherein, when the cover is closed, at least the blade nearest the bottom side of the container body of the blades of the cutter is formed so that the radius of curvature (R) of the blade at a tip is 100μm or more and less than 145μm, the height (H) of burrs at the tip of the blade is less than 50μm, and the relation between the radius of curvature (R) and the height (H) of burrs at the tip of the blade is H (μm) ≥ R (μm) − 95, whereby the wrap film can be easily and surely cut off, and the wrap film can be prevented from being ruptured vertically.
