Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a cushioning material for packaging which is used when packaging various articles and is detachably attached to a corrugated paper cushion body made of a foam material.

[0002]

[Prior Art]

 Styrofoam is widely used as a packaging material because it is lightweight, inexpensive, and has a high cushioning property. When this styrofoam is used as a cushioning material, there are two types, one that is entirely molded into the reverse shape of the product, and one that is bonded to corrugated cardboard with an adhesive. The former has a concavo-convex relationship opposite to the product shape, and since it is integrated as a whole, it exerts a high function as a packaging material, but it has the drawback of being expensive because it is molded. On the other hand, the latter has the advantage that it can be manufactured inexpensively because the foam is bonded to the corrugated paper.

In the case of a corrugated cardboard on which a foam is adhered, only the foam is cut and reused after use. That is, used foam is melted into pellets, which are then reused after being formed into piles, sleepers, or other shapes. In this case, when the foam adhered to the corrugated ball paper is torn off, a large amount of corrugated paper pieces adhere to the foam, and when the foam is melted in such a state, Corrugated paper pieces are mixed in the melted material of the foam, which is not preferable.
