Claims

[Scope of utility model registration request]

(1) In a packaging cushioning material in which a large number of score lines are made in an elastic sheet and the packaged item is accommodated in the part where the score lines are made, the outer edge of each score line is approximately constant on the imaginary outer circumferential line. The forces are formed so that the inner ends are located at regular intervals on the virtual inner circumferential line,
A packaging cushioning material characterized in that the inner and outer ends of each of the score lines are formed at different positions in the circumferential direction.

(2) The cushioning material for packaging according to claim 1, wherein the cut line is a curved line whose radius of curvature gradually decreases from the outer end to the inner end.

(3) The scope of the utility model registration claim, characterized in that the above-mentioned cut line is a wavy curve that swings to both sides of the virtual curve, the radius of curvature of which gradually decreases from the outer end to the inner end. The packaging cushioning material according to item 2.

(4) The packaging cushioning material according to any one of claims 1 to 3, wherein the elastic sheet is made of a porous material having air permeability.
