The present invention relates to a packaging box (Packaging or Packing box), and more particularly, to a buffer packaging box capable of preventing damage to an article by a self-cushioning effect.

A packaging box or packaging container is commonly used for transport and storage of various items, and is made of paper, plastic, metal, wood, and the like. Recently, due to the activation of e-commerce and Internet shopping, a parcel (or delivery) service that delivers goods directly to a place requested by consumers is rapidly increasing. In the courier service, it is common to package and transport goods in boxes, and the boxes used at this time are often called parcel boxes. Delivery boxes are mainly made by cutting out recyclable paper and corrugated board.

A packaging box made by cutting paper and cardboard can be easily deformed by external force. In addition, there is a high possibility that the product may be damaged by the impact acting on the packaging box. In order to prevent breakage when packaging fragile items such as glass products, the empty space inside the packaging box is filled with expanded polystyrene (EPS), expanded polypropylene (EPP), air cap (aka 'bubble'). ), packing cushioning materials such as paper, or packing fillers. Packaging boxes and packaging cushioning materials should be separated and disposed of according to the volume-based waste system in effect to reduce the amount of waste and to recycle them. In particular, the use of synthetic resin packaging cushioning materials such as EPS, EPP, and air cap is increasingly regulated to save resources and promote recycling. Therefore, it is recommended to use eco-friendly products that can prevent damage to the product and prevent environmental pollution in the packaging box.
