In a usage state, a packaging film is stuck in such a manner as to cover an opening of a container, in a state in which a tension is applied along in the longitudinal direction. A through-hole (13A) assuming a shape having at least one protrusive corner part (31) is provided, and center lines of all the protrusive corner parts (31) of the through-hole (13A) are inclined with respect to an orthogonal line (B) orthogonal to a tension direction (A).SELECTED DRAWING: Figure 2 |
