【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a partial plan view showing an example of the sheet-like packaging material of the present invention, FIG. 2 is an enlarged plan view of a main part thereof, and FIG. 3 is a plan view showing a state in which the sheet-like packaging material of the present invention is pulled in the vertical direction. FIG. 4, FIG. 4 is a perspective view showing another example of the present invention, FIG. 5 is a perspective view showing a state in which an article to be packaged is placed on the sheet-like packaging material shown in FIG. 1, and FIG. It is a perspective view shown.

As shown in FIG. 1, the sheet-like packaging material 10 of the present invention comprises a flexible sheet base material 11 having a plurality of cut row portions 20, 20, 20, ... Formed in multiple rows. .

As a material of the soft sheet base material 11 that constitutes the sheet-shaped packaging material 10, it is necessary to have appropriate flexibility and elasticity so that the accommodated article is not easily scratched and easily conforms to the outer shape of the article. Is preferable. For example, a sheet material made of a foam such as polyethylene, polypropylene or polystyrene or polyurethane is a desirable material. If necessary, a composite sheet-shaped product obtained by laminating these may be used.

The cut row portions 20, 20 ... Formed on the soft sheet base material 11 are for forming a mesh on the sheet-shaped packaging material 10, and as is well understood from FIG. The notches 21 and the connecting portions 23 having a predetermined length Q are alternately provided in a row. The cut row portions 20 are formed in multiple rows on the sheet base material 11 with a constant width interval R.

The length Q of the connecting portion 23 in each cut row portion 20 is formed to be substantially the same as the width interval R of each cut row portion 20, 20 ,. The position is provided so as to correspond to a substantially central position C of the cut portions 21 in the adjacent cut row portions 20. Therefore, the length and position of each connection portion 23 in one row correspond to the connection portion 23 of the other cut row portion 20 placed one row with respect to that row.

With such a configuration, when the cut portion 21 is extended when the sheet-shaped packaging material 10 covers the article to be packaged, each cut portion 21 and the connection portion 23 are arranged as shown in FIG. As shown, it is possible to form a beautiful parallelogram (diamond-shaped) mesh portion N having mesh legs M and intersections S of uniform width. Arrow symbols d1 and d2 in FIG. 3 indicate the extending direction.

The length P of the cut portion 21 and the length Q of the connection portion 23 (width interval R of the cut row portion) thus define the width of the mesh leg portion M and the size of the mesh portion N. These are appropriately determined depending on the material and thickness of the soft sheet base material 11 constituting the sheet-shaped packaging material 10, the property and size of the packaged object, and the like. In this embodiment, the length P of the cut portion 21 is 40 mm, the length Q of the connection portion 23 and the width interval R of the cut row portion are 4.5 mm.

The shape of the sheet-shaped packaging material 10 can be any shape depending on the articles to be packaged. In the embodiments, the most commonly used rectangular shape is shown for convenience of explanation, but it may be formed into a circular shape, a polygonal shape, or a special shape depending on the shape of the product.

Further, as shown in FIG. 4, the packaging material is continuously formed as a roll-shaped material 30, and the user cuts it into a desired size with a cutter or the like, if necessary. May be.

Further, as shown by reference numeral 35 in FIG. 4, an adhesive layer may be formed in advance on the edge portion of the packaging material. The adhesive layer 35 is made of a well-known double-sided adhesive tape, and the use surface is covered with release paper or the like.

FIG. 5 and FIG. 6 show an example of packaging an article by the sheet-shaped packaging material 10. First, the article B to be packaged (Yamaimo in this example) is placed on the upper surface of the sheet-shaped packaging material 10. Then, as shown in FIG. 5, one end 10A side of the sheet-like packaging material 10 is wrapped around the article B to be packaged, and the other end 10B side is wrapped from above to be wrapped.

At this time, since the notches 21 of the notch line portion 20 freely expand along the shape of the article B to be packaged, the shape and size of the articles to be accommodated can be absorbed and softened. It can be packaged quickly and reliably.

Further, as shown in FIG. 5, if the one end portion 10B is provided with the adhesive layer 35 as described above, the article B to be packaged can be easily and easily used without using a special tightening tool or a fixing member. Can be surely wrapped.

The packaging material of the present invention is a roll cutter in which a continuous sheet or a soft sheet base material cut into a predetermined shape is provided with blade portions forming predetermined cut portions and connection portions in multiple rows at predetermined intervals. Alternatively, it can be easily manufactured by cutting with a press. The pressure-sensitive adhesive layer can also be easily formed by attaching a double-sided pressure-sensitive adhesive tape by a known means.
