Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention 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 for a synthetic resin automobile bumper or the like as an object to be packaged.

[0002]

2. Description of the Related Art For example, automobile bumpers made of synthetic resin are:
Conventionally, it is packed in a polyethylene bag and then packed in an outer box made of corrugated paper and transported, so the packaging work is troublesome.Polyethylene generates static electricity, and sparks contaminate the packaged object. There was a disadvantage. Further, when a packaged object having a curved shape like a bumper is put in an outer box, the dead space is large, and therefore the outer box becomes large.

[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 effect and is not suitable as a packaging material for a packaged object such as a bumper.

[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 wrap a package to be buffered without an outer box and that does not generate static electricity.

[0005]

According to the present invention, in a packaging sheet in which a fiber skin sheet and a cushioning material sheet are laminated, the fiber skin sheet is kraft paper, the cushioning material sheet is felt, The felt is sandwiched between the kraft papers on both sides, and the kraft paper and the felt are joined at a plurality of locations by embossed glue portions.

[0006]

[0007]

In practicing the present invention, two layers of felt and three layers of kraft paper may have a sandwich structure.

[0009] Therefore, by combining a relatively hard fiber skin sheet and a relatively soft felt, for example, when packaging an automobile bumper made of a synthetic resin without using an outer box, the operation can be easily performed. It can be carried out. Since no static electricity is generated, the object to be packaged is not contaminated by sparks.

Further, the felt has high flexibility as well as flexibility, so that the packaged object wrapped with the wrapping sheet according to the present invention can be transported as it is and does not need to be put in an outer box.

[0011] Since the felt is partially glued to the fiber skin sheet, the portion not glued can make a slight relative movement, and can simultaneously improve the strength and the cushioning effect. Also, the flexibility is improved.
Therefore, the packaging operation is simple and easy.

[0012]

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

As shown in FIG. 1, a wrapping sheet generally indicated by reference numeral 1B has a kraft paper 2, which is a fiber skin sheet, and a felt 3, which is a cushioning sheet, laminated in a sandwich form. That is, the kraft paper 2, the felt 3 and the kraft paper 2 are laminated, and as shown in FIG. 2, the kraft paper 2 and the felt 3 are joined to each other by embossed glue portions 4 at a plurality of places.

[0014]

The felt constituting the cushioning material sheet preferably has a thickness of about 10 mm, is light and rich in cushioning, and is easily bent. Since the felt is joined to the fiber skin sheet in this way, a flexible packaging sheet having high tensile strength can be obtained. As a result, the efficiency of the packaging operation is improved.

[0016]

[0017]

FIG. 3 shows another embodiment of the present invention. This wrapping sheet 1C is made by laminating kraft paper 2, felt 3, kraft paper 2, felt 3 and kraft paper 2 and attaching a glue portion 4 (see FIG. 3). 2).

[0019]

[0020]

[Effects of the Invention] As described above, the present invention has the following excellent effects. (A) Since neither kraft paper nor felt generates static electricity, there is no dirt on the packaged object due to sparks. (B) Partial gluing provides flexibility, and slight relative movement improves cushioning and packaging workability. (C) It is lightweight, has tensile strength, and is easily packaged. Also, external means such as an outer box is not required. (D) Since both surfaces are made of kraft paper, the wrapped body comes into contact with the kraft paper, so that the fibers are not entangled with the wrapped body like felt or nonwoven fabric.
