ABSTRACT:
A wrap film containing box in which a projected portion of a thin sheet out of a serrated member serves as a tab and in which a thin sheet body on the back of the serrated member plays the role of reducing the fastening strength. Therefore, the serrated member can be removed easily and safely without reducing the rigidity of a cardboard portion of the box body where the serrated member is mounted (i.e., without impairing the cutting performance of the serrated member).
