Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and in particular to a cushioning packaging box. Background Art

[0002] Packaging is an essential step after the production of home appliances. Almost all home appliances cannot be separated from the protection of packaging boxes.

[0003] There are many kinds of packaging materials and packaging structures for existing home appliances. At present, the packaging method on the market mainly uses paper plastic as the outer box and expandable polyethylene or expandable polystyrene as the inner lining. In addition to the main product, home appliances on the market currently have corresponding accessories. When packaging home appliances, the main product and the corresponding accessories are placed in the same packaging box and the product is transported.

[0004] The recycling cost of expandable polyethylene and expandable polystyrene is high, and after being discarded, they become white garbage that pollutes the environment. The materials are extremely environmentally unfriendly. When the main product and accessories of home appliances are placed in the same packaging box, they will inevitably be damaged by collision during packaging and transportation. The single-layer packaging box structure cannot provide a good buffer for the collision of the main product during transportation, which often causes bumps and damages on the surface of the main product, affecting the appearance of the product and even affecting the performance of the product.
