Abstract

(57) [Abstract] [PROBLEMS] To obtain a packaging sheet that is highly cushioning, flexible, and easy to package. SOLUTION: A packaging sheet (1) in which a felt (3) and a fiber skin sheet (2) are partially glued (4, 4a) and joined.

Description

[Detailed description of the device]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packaging sheet in which a fiber skin sheet and a cushioning material sheet are laminated, and more particularly to a packaging sheet such as an automobile bumper made of a synthetic resin as an article to be packaged.

[0002]

[Prior art]

 For example, automobile bumpers made of synthetic resin are conventionally packed in a polyethylene bag and then packed in an outer box made of corrugated cardboard, which is transferred to the outside. However, there is a drawback that the packaged object becomes dirty due to sparks. Furthermore, if a packaged object with a curved shape like a bumper is put in the outer box, there is a lot of dead space, which makes the outer box large.

Various types of packaging materials having a cushioning effect are generally known. For example, Japanese Utility Model Laid-Open No. 52-113079 discloses a corrugated cardboard support on which a fiber wrap is laminated. There is. However, corrugated board does not fit well into complicated shapes, and therefore the dead space becomes large. Further, Japanese Utility Model Application Laid-Open No. 52-136806 discloses a container or bag body in which a paper body is partially coated with an adhesive and adhered to a synthetic resin cloth. However, such a known technique has no cushioning effect and is unsuitable as a packaging material for a packaged object such as a bumper.

[0004]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a packaging sheet which can sufficiently wrap a packaged object without an outer box and does not generate static electricity.

[0005]

[Means for Solving the Problems]

 According to the present invention, in a packaging sheet in which a fiber skin sheet and a cushioning material sheet are laminated, the cushioning material sheet is made of felt, and the fiber skin sheet and the thin paper laminated product are partially glued. Are joined together.

Kraft paper is preferable for the above-mentioned fiber skin sheet because of its environment resistance, light weight, price, and ease of wrapping, but a reinforcing cloth or the like can be used.

Further, it is preferable that the partial glued portions are formed in a plurality of embossed shapes or tape shapes.

In implementing the present invention, either or both of the fiber skin sheet and the felt may be alternately joined.

Therefore, when a relatively hard fiber skin sheet and a relatively soft felt are combined, for example, when the bumper of an automobile made of synthetic resin is packaged without using an outer box, the work is easy. Can be done. And since no static electricity is generated, the package is not contaminated by sparks.

Further, since the felt has a high flexibility and a high cushioning resistance, the packaged object wrapped with the packaging sheet according to the present invention can be transferred as it is and does not need to be put in the outer box.

Further, since the felt is partially glued to the fiber skin sheet, the non-glued portion can make some relative movement, and the strength and the cushioning effect can be simultaneously improved. Also, the flexibility is improved. Therefore, the packaging work is simple and easy.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, a packaging sheet generally indicated by reference numeral 1 is obtained by laminating a fiber skin sheet, for example, kraft paper 2, and a felt sheet 3, which is a cushioning material sheet. 3 and the thin paper laminated paper are joined to each other at a plurality of places by the embossed glued portion 4.

As the fiber skin sheet, the kraft paper 2 is preferable in terms of environment resistance, light weight, price, and easiness of wrapping. However, the material is not limited to this, and a reinforcing cloth such as a woven cloth or a non-woven cloth can be used.

The felt constituting the cushioning material sheet preferably has a thickness of about 10 mm, is light and rich in cushioning, and is easy to bend. Since the felt is bonded to the fiber skin sheet in this manner, a flexible packaging sheet having tensile strength can be obtained. As a result, the efficiency of the packaging work is improved.

The gluing portion 4 is not limited to the embossed shape, but may be a tape-shaped long gluing portion 4a like the packaging sheet 1A shown in FIG.

FIG. 4 shows another embodiment of the present invention. This packaging sheet 1B has a kraft paper 2, a felt 3 and a kraft paper 2 laminated to each other, and a gluing part 4 (or a gluing part 4 in FIG. 3). Joined in a).

FIG. 5 also shows another embodiment of the present invention, which is a packaging sheet 1c in which a kraft paper 2, a felt 3, a kraft paper 2, a felt 3 and a kraft paper 2 are laminated, and a gluing portion 4 (or It is joined at the glued portion 4a) in FIG.

Although these packaging sheets 1B and 1C are thicker than the packaging sheet 1, a packaging sheet having a suitable thickness can be selected according to the product to be packaged.

[0020]

[Effect of the invention]

 As described above, the present invention has the following excellent effects. (A) Since neither the fiber skin sheet (for example, kraft paper) nor the felt does not generate static electricity, the packaged object is not soiled by the spark. (B) Partial gluing provides flexibility, and a slight relative movement improves cushioning and packaging workability. (C) It is lightweight and has tensile strength, and packaging work is easy. Also, no external means such as an outer box is required.
