Problems solved by technology

But for example, in the production process of the golden boundary line of the whole packaging box of Zhonghua Cigarette Packet, the red part needs to be pasted on the golden part to form the facial paper, and then the cardboard hard board is pasted on the back of the golden part of the facial paper.
