To meet the needs of China National Tobacco Corporation, we commissioned our engineers to design a new type of corrugated plastic turnover box to replace the original cardboard turnover box as outer packaging. The four walls of the box are required to be divided into two colors, and the two walls of the opposite box have the same color.
After in-depth research, and trial , and countless tests of our company, the original production line was modified, and a shunt design was carried out in the abrasive part. The plate with completely separated colors and well-defined boundaries was successfully produced. In the binding stage of the box, the original four One binding line is reduced to two binding lines, which greatly saves the processing cost of the box and improves production efficiency.
Coropak has invention patents.
