Description

[Technical field]

[0001] The invention specifically relates to a method for manufacturing a packaging structure made of multi-layer corrugated paperboard. [Background technology]

[0002] Packaging boxes are used to wrap products to protect and decorate them, but traditional packaging boxes have a space for placing products inside the box. Traditional packaging boxes need to ensure the hardness of the material and, in order to improve the protective effect of the packaging boxes and the versatility of the packaging boxes for materials, the applicant has studied a packaging structure formed by stacking multiple layers of cardboard layer by layer, and each layer of sheet material is provided with a hollow groove of a preset shape. After the layers of sheet material are stacked, the hollow grooves of each layer are combined to form a cavity for placing items. This new packaging structure is not only highly versatile for different materials, but also sheet materials such as honeycomb cardboard, hard cardboard, and paper can be made into this packaging structure by stacking and combining.

[0003] Reference Figures 1 to 3 This stacked packaging structure consists of a bottom sheet material a1 located at the bottom layer and an upper sheet material a2 stacked on the bottom sheet material a1. The bottom sheet material a1 and the upper sheet material a2 are stacked in sequence. The upper sheet material a2 has multiple hollow grooves a21 preset thereon. After they are stacked, the different hollow grooves a21 are combined to form a larger accommodating cavity for accommodating items and placing products.

[0004] However, to manufacture the above packaging structure, each layer of sheet material needs to be glued and stacked. Manual operation requires sorting out different materials and then gluing and stacking them one by one in order.
