The present invention relates to the packaging of a box, and more specifically, a packing cushioning material that can accommodate a product compactly inside a packing box and protect it from external shocks, and can easily store the items attached to the product. It is about.

When loading a product in a packaging box, an empty space may be formed between the product and another product or between the product and the packaging box after loading the product. Such empty space may be caused by the shape of the package, and may be formed by the arrangement or size difference of the packages when storing two or more packages. As such, the products accommodated in the packaging box including the empty space may move freely in the box and may be damaged by a collision. When an external shock is transmitted, the shock is delivered to the product without buffering and the product is transported. Breakage or failure may occur. In addition, the box may be recessed or crushed by an external force such as a load, thereby making it difficult to store and load the box.

Accordingly, the packaging cushioning material is used to fill an empty space in a packaging box or to protect the box and the product contained in the box by interposing the products. Conventional packaging cushioning material is manufactured by injection molding of styrofoam, polyethylene, or PVC resin, and is packaged and distributed to the outside vulnerable products such as electronic products or mobile phones.

However, these packaging cushions are not easily stored after opening the product, and most of them are thrown away as garbage, and once molded, they cannot be recycled, making it difficult to recycle, and neglected or incinerated polystyrene and PVC resins There is a risk of contamination.

Therefore, in order to solve this problem, a cushioning material for packaging is manufactured using paper or cardboard. The corrugated cushioning material is recyclable, and because it is inexpensive, it has an economic advantage, and is easy to be stored because it is easy to bend the body itself.

However, the conventional cushioning material for packaging using corrugated cardboard is not enough storage space is difficult to accommodate the secondary material of the product is often accommodate the secondary material of the product in the space between the remaining product. In addition, even in the case of the packaging cushioning material provided with the storage space, when the external force is applied to the outside, it often occurs to escape from the storage space. As a result, the packing cushion cannot completely receive and protect the product and the product may be damaged.

In addition, the conventional packaging cushioning material is very difficult to manufacture due to the complicated structure even if a plurality of storage spaces are provided for accommodating products and auxiliary materials, and the assembling process is also complicated. Therefore, the consumption of the fabric for making a single packaging cushioning material is large, and the production cost and manufacturing time is large, economical consumption is large.

One object of the present invention for achieving the above-described present invention is to provide a shock absorber for packaging that is simple in structure of the shock absorber and can stably accommodate the product.

In addition, another object of the present invention is to provide a cushioning material for packaging that can reduce the production cost of the fabric is low and easily produced.

In addition, another object of the present invention is to provide a packaging buffer for easily forming a storage space suitable for the size and shape of the package.
