Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cushioning material for synthetic paper packaging having embossed protrusions on both sides.

[0002]

[Prior Art]

 Conventionally, a widely used cushioning material for packaging is made of Styrofoam. The foamed polystyrene cushioning material is widely used in the electric appliances and heavy packaging fields because it has advantages such as light weight, great cushioning effect, and easy molding process.

However, since the foam cushioning material made of Styrofoam is a petrochemical product that has recently been particularly regarded as a problem, it is necessary to dispose of its industrial waste for the purpose of promoting depletion of resources and preserving the global environment. In particular, it is becoming a global problem.

In some countries, it is already prohibited by law to use this type of Styrofoam as a packaging material, and it cannot be used for export products from Japan.

As the cushioning material for packaging, foamed vinyl chloride foam, urethane, cardboard and the like are used in addition to the polystyrene foam.

However, since foamed vinyl chloride foam and urethane are petrochemical products similar to styrofoam, there is a problem in disposal and cardboard can be easily used, but on the other hand, laborious work of lamination is required. Not only that, but it also has the drawback of poor compression resistance.

When this type of cushioning material for packaging is used as a packaging container, if the material is styrofoam, foamed vinyl chloride foam, or urethane, it must be molded into the shape of the container. If the cardboard is a corrugated cardboard, the corrugated cardboard has a flat plate shape, so it was necessary to bend the cardboard into a container shape.

[0008]

[Problems to be solved by the device]

 Therefore, conventional materials such as Styrofoam, vinyl chloride foam, and urethane had problems of resource depletion and deterioration of the global environment.

When the packaging cushioning material made of corrugated cardboard is used as a packaging container, the corner portion where the packaged object abuts is likely to be impacted, and the abutting portion is formed of a material such as styrofoam. Since it is necessary to reinforce with a reinforcing piece and the side surface of the packaging container is flat, there is a problem of lack of strength.

In view of such drawbacks, the present invention suppresses resource depletion, is advantageous in waste disposal and recyclability, can preserve the environment, and is excellent in strength for synthetic paper packaging. The purpose is to provide a cushioning material.

[0011]

[Means for Solving the Problems]

 According to the present invention, a large number of concave and convex liners are provided on both sides of a synthetic paper body, and a large number of concave and convex embossing projections are provided on one side of the synthetic paper body. The synthetic paper body is bent along the groove.

[0012]

[Action]

 The operation of the present invention will be described.

When the synthetic paper packaging cushioning material according to the present invention is used as a packaging container, the packaging container is formed by bending the synthetic paper body along the crease grooves of the synthetic paper body. Therefore, the portion of the packaged product that comes into contact with the corners is cushioned and reinforced by the uneven embossing protrusions and the uneven liner of the cushioning material made of synthetic paper, so that it can be reliably protected.

In addition, after using the synthetic paper packaging cushioning material as a packaging container, the folded shape is returned to its original state so that a large number of synthetic paper packaging cushioning materials are stacked and transported. Can be easy.

The method of forming the uneven embossing protrusion 18 is a male mold or a female mold provided with the uneven embossing protrusion, and a pair of mold rolls provided with the uneven embossing protrusion on the peripheral surface. However, the method and means are not particularly limited as long as they are means provided with the embossed protrusions 18 having a concave-convex shape.

Further, during the formation of the embossed projections 18 having a concave-convex shape, a large number of the concave-convex liners 16 of the synthetic paper body 14 are pressed to form ribs 24, which are used as the cushioning material 12 for packaging synthetic paper. 24 gives strength for reinforcement.

The synthetic paper main body 14 provided with the uneven embossed projections 18 is cut into a substantially square shape to form the synthetic paper cushioning material 12.

As shown in FIG. 2, a fold groove 20 having a cross shape and a rhombus shape is provided on one side surface of the cushioning material 12 made of synthetic paper of the present embodiment, and the fold groove 20 of the cross shape is formed. A part is a notch (two-dot chain line in FIG. 2) 22. Although the fold groove 20 and the notch 22 are shown separately in the drawing for the sake of description, the notch 22 is actually provided on the same line as the fold groove 20.

In FIG. 2, the embossing protrusion 18 and the rib 24 are omitted for the sake of explanation.

The folding process of the synthetic paper packaging cushioning material 12 of the present embodiment is performed by stacking the substantially square corners along the diamond-shaped fold groove 20 at the center point, and then forming the cross shape. By bending at a right angle along the crease groove 20 and then stacking two adjacent surfaces each having a notch 22, as shown in FIG. To do.

The packaging container according to the present embodiment is used after being brought into contact with a corner portion of an article to be packaged and then packaging the article to be packaged.
