The packing carton is a core carrier for modern logistics and commodity protection, and its design needs to consider protection, cost, environmental protection and user experience. With the development of technology, future cartons will be more intelligent and sustainable.

[0003] The existing carton does not have a multilayer reinforcing structure in use, such as the paper box disclosed in application No. CN201010214007.5. The existing carton of this type is usually single-layered and has low structural rigidity. The single-layer carton is composed of a single layer of corrugated paperboard and lacks a multilayer reinforcing structure. When subjected to vertical pressure, such as stacking or transportation jolting, the single-layer carton is prone to corrugated deformation and box collapse, resulting in direct pressure damage to the internal goods. The single-layer carton usually uses adhesive tape for sealing, which cannot achieve rapid sealing and lacks a built-in drying box for active moisture-proof function. In long-term storage or cross-border transportation, the adhesive tape is prone to aging and falling off, causing accidental opening of the box or moisture intrusion. The single-layer carton does not have reinforcing properties and is prone to crease cracking after multiple folding and unfolding, reducing the service life.
