Disassembly structure: flat packing, reduce the volume of product packaging, convenient logistics transportation and handling, effectively reduce the rate of damage.

Internal packaging: double-layer foam board is used to cushion and resist pressure, and the four corners are covered with kraft paper to prevent knock and collision. Each part is wrapped with pearl cotton to prevent abrasion and skid, thus greatly reducing the damage to the product during transportation.

External packaging: The external carton is made of double-sided five-layer corrugated paper, namely three-core double-sided seven-layer cardboard, with two layers of cardboard and three layers of corrugated base paper.

Special packing: for some commodities or special customers, we will use the form of carton + wooden frame/wooden case for packing, to protect the products intact to the greatest extent.
