FIG. 6 is a plan view showing an example in which is formed into a spiral shape.

First, as shown in FIG. 1, the sheet-like packaging material 10 of the present invention is made of a soft sheet base material 11 and has an article accommodation portion 12 for an article to be packaged. In this embodiment, the sheet-shaped packaging material 10 is formed into a substantially oval shape suitable for packaging grapes and the like.

The soft sheet base material 11 used for the sheet-like packaging material 10 has appropriate flexibility and elasticity so that the articles to be contained are not easily scratched and easily conform to the outer shape of the articles. Materials are preferably used. For example, it is a sheet material made of foam such as polyethylene, polypropylene, polystyrene or polyurethane. A sheet-shaped member obtained by appropriately selecting and stacking these may be used as necessary.

The article accommodating portion 12 includes a plurality of cut row portions 1.
3, 13, 13, ... The cut row portions 13, 13, ... Are each formed of an arc-shaped cut portion 15 engraved in a row through the connection portion 14, and the article storage portion 1 is provided.
Many are arranged concentrically from the center O of the two at intervals of a constant width P. The cut row portion 13 forms the mesh by opening the arc-shaped cut portion 15 when the packaging material 10 is pulled due to the shape and weight of the packaged object.

As will be better understood from FIG. 2, the connecting portion 14 is provided with a substantially constant width Q at a position where the circle C forming one cut row portion 13 is equally divided into a certain number. The number of divisions of the circumference C determines the number of the connecting portions 14 and the arcuate cut portions 15 formed in one cut row portion 13, and is eight in this example.

The positions of the connecting portions 14 are provided at regular intervals so as to correspond to the connecting portions 14 of every other row of the cut rows 13, and are formed in a radial shape as a whole as a whole. In addition, the connection portion 14 is formed by the adjacent cut row portion 1
It is formed so as to correspond to a substantially central position R of the length of the cut portion 15 of 3. Therefore, these cut row portions 13, 13, 1
3, ... Form one cut line portion 13 by a circle C divided into eight, and also form a circle C1 which is also divided into eight and rotated 22.5 ° apart from the circle C by a constant width P. By doing so, adjacent cut row portions 13 are formed.

The width Q of each connecting portion 14 is preferably formed to be substantially the same as the engraving interval P of the cut row portion 13. Thereby, the mesh of the package can be developed with a beautiful appearance and surely. The width Q can be appropriately determined depending on the weight and shape of the article to be packaged, but if the width Q is too narrow, the connection portion may be cut due to the weight of the article. Further, if the width is too wide, the mesh does not develop effectively and it is difficult to follow the shape of the article, so in this example, it is formed to 4 mm.

A plurality of notches 15 are formed in one notch line portion 13 via the connecting portion 14. One arcuate notch 15 has two connecting portions 14 adjacent to each other in the row,
It is surrounded by 14 and the connecting portions 14 and 14 of the notch row portions 13 on both sides to form one mesh on the packaging material. The numbers of the cut line portions 13 and the arc-shaped cut portions 15 can be appropriately determined depending on the size and shape of the article to be stored.

To be done.

At this time, since the degree of expansion of the arcuate cut 15 changes freely along the shape of the article, the size of the article to be accommodated can be absorbed and the article can be softly and reliably packaged. it can. Further, since the cut row portion 13 expands and contracts in the form of a mesh, the entire outer circumference of the article can be quickly wrapped by the weight of the article M placed on the article container 12. In this example, ears 16, 16 are formed at both ends in the longitudinal direction of the sheet-shaped packaging material 10. The ears 16 are configured to have a wide width so that the ends of the packaging material picked up when the article is packaged are not cut.

An engagement portion 17 is provided near the ear portion 16. As shown in the drawing, the engaging portion 17 is for retaining the packaging shape by engaging the pulled-up ear portion 16 by hooking it on the vine or stalk of the grape or apple to be packaged, In this example, a notch portion close to the ear 16 is used.

In the packaging material of the present invention, a soft sheet base material mainly composed of a synthetic resin foam having an appropriate thickness is cut into a predetermined size capable of packaging the article M to be accommodated, and the cut portions are arranged by a press or the like.
