[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging sheet for a bumper made of, for example, an automobile synthetic resin.

[0002]

2. Description of the Related Art For example, a bumper for an automobile made of a synthetic resin has conventionally been put in a bag made of polyethylene and usually packed in an outer box made of corrugated paper. However, as in the past, when a plastic bumper made of a synthetic resin is put in a plastic bag,
Static electricity is generated and the bumper becomes dirty by sparks. Also, since the bumper has a curved shape on both sides, the outer box becomes large and there is much dead space.

[0003] Also, various packaging materials having a buffering action are generally known.
No. 079 discloses that a fiber wrap is overlapped on a support made of cardboard. However, the cardboard is not well-adapted to those having a complicated shape, so that the dead space increases. 52
JP-A-136806 discloses a container or bag body in which an adhesive is partially applied to a paper body and bonded to a synthetic resin cloth. However, such a known technique does not have a buffering action and is not suitable as a packaging material.

[0004]

[Problem to be solved by the present invention]
It is an object of the present invention to provide a packaging sheet that can sufficiently package an object to be packaged without an outer box and that does not generate static electricity.

[0005]

According to the present invention, in a packaging sheet in which a textile skin sheet and a cushioning material sheet are laminated, the textile skin sheet is kraft paper, and the cushioning material sheet has a plurality of positions. It is a thin paper laminate joined by an embossed glued portion, and the kraft paper and the thin paper laminated product are joined at a plurality of locations by an embossed glued portion.

As described above, the packaging sheet of the present invention constructed as described above directly packs a packaged object such as a synthetic resin automobile bumper with kraft paper outside. Then the light thin paper laminate comes in contact with the packaged item,
The packaged item is not damaged. In addition, the thin paper laminate has a good shock-absorbing effect against an impact, so that an outer box or the like is not required, so that the number of packaging steps is reduced.

Since kraft paper is thin and durable, it is not bulky, it is resistant to impact, it does not break easily, and it is lightweight, so it is suitable as an outer package. That is,
The packaged object can be protected against external force.

Since the kraft paper and the thin paper laminate and the thin paper laminate itself are partially joined by a plurality of embossed glued portions, the thin paper constituting the kraft paper and the thin paper laminate does not fall apart. In addition, since there is a relative misalignment in bending at the time of packaging and flexibility, the packaging operation is easy. The gluing portion can be easily glued by a known gluing device, and is easy to manufacture. Since the sheet is mainly made of paper, there is no generation of static electricity.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, a packaging sheet indicated by reference numeral 1 is composed of a kraft paper 2 as a fiber skin sheet and a thin paper laminate 3 as a cushioning material sheet. In addition, the thin paper laminated paper is formed by joining the embossed glue portions 4 at a plurality of locations.

[0016]

The thin paper laminate 3 constituting the cushioning material sheet is formed by laminating ten sheets of about 1 mm, and the total thickness of the packaging sheet 1 is desirably about 10 mm. Then, as shown in the drawing, they are joined to each other by a partial gluing portion 4, so that they are not separated from each other and have high flexibility. Such a thin paper laminate 3 is light,
It is preferable as this kind of packaging material because it has a high buffering property and is easy to bend. However, since it is weak in strength, a good packaging sheet 1 can be obtained by combining it with the fiber skin sheet 2.

[0018]

Next, the operation will be described.

For example, when packaging an object to be packaged such as a synthetic resin bumper, the kraft paper 2 is placed outside and the thin paper laminate 3 is placed inside. At that time, the wrapping sheet 1 is integrated by the embossed glue portion 4, and a slight relative movement is allowed between the thin paper laminate 3 itself and the kraft paper and the thin paper laminate. It is flexible and flexible, which improves the packaging operation.

Since the packaging sheet 1 is a paper product,
There is no generation of static electricity, and the package does not become dirty by discharge.

And since the thin paper laminate 3 is rich in cushioning properties,
In combination with the robustness of the kraft paper 2, the packaged material can be sufficiently protected against impact force. Therefore, an outer box is not required.

[0026]

[Effects of the Invention] As described above, according to the present invention, the following excellent effects can be obtained. (A) By combining the durable and lightweight points of kraft paper with the cushioning properties of a thin paper laminate, a packaging sheet that can sufficiently protect a packaged object from external force can be obtained. (B) Since the sheets are joined to each other at the embossed glued portions, they can be partially moved relative to each other, and can be easily wrapped with flexibility. (C) The embossed gluing portion can be implemented in a known device and is easy to manufacture. (D) Since it is a paper product, it does not stain the package due to discharge due to the generation of static electricity, and there is no pollution when incinerated after use.
