Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a foldable and deformation-resistant heavy-duty packaging box. Background Technology

[0002] As an indispensable tool in modern logistics transportation and commodity packaging, packaging boxes not only protect the contents from external impacts, but also require good load-bearing capacity, ease of handling and storage, etc. Especially in the packaging and transportation of heavy goods, higher requirements are placed on the structural strength, pressure resistance and cushioning performance of packaging boxes.

[0003] Traditional heavy-duty packaging boxes are mostly made of wooden boxes or metal frames combined with rigid plastic boards. Although they can meet the requirements of load-bearing and protection to a certain extent, they generally have problems such as bulky structure, difficulty in handling, and difficulty in folding and storing. In addition, traditional packaging boxes are usually integral structures that cannot be disassembled or folded, occupying a large amount of storage space when not in use, increasing logistics costs and inconvenience of use.
