Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a foldable packaging box. Background Technology

[0002] Ordinary cardboard boxes are often discarded after use, resulting in both material waste and environmental pollution. Even recycled cardboard boxes, such as the foldable boxes available on the market, have drawbacks such as cumbersome folding, low packaging efficiency, difficulty in storage and organization, large size after folding, and susceptibility to damage during folding, all of which affect their recyclability.

[0003] A foldable packaging box is disclosed in the existing announcement number CN108238333A. The packaging box includes a base plate, a front plate, a rear plate, and two side plates connected to the base plate on all four sides. The base plate, front plate, rear plate, and side plates together form the box body. The packaging box is a one-piece folding structure, and the front plate and side plates can be folded flat towards the inside of the box. This one-piece folding structure allows for rapid and efficient manufacturing and assembly. After forming, it can be folded flat, and the folded size is neat and compact, saving space, facilitating organization and carrying, and aiding in recycling after use.

[0004] While existing technologies can achieve folding of packaging boxes, they are prone to deformation after being formed into a box. To solve the above technical problems, we propose a foldable packaging box. Utility Model Content
