The processing process of China paper coffee cups raw material is divided into base paper coating, slitting, sampling, typesetting, printing, film cutting, disinfection, and forming. The first is to deal with the width of the paper, and the cutting method is determined according to the facing and method of the printing plate. Next is the printing of China paper coffee cups raw material. There are two ways of printing: offset printing and kneading printing, while paper cup printing generally uses flexographic water-based ink. Then there is die-cutting, which is to cut the paper with the printed pattern into pieces of corporate fan-shaped paper, and some machines can die-cut it by themselves.
Finally, the forming of the paper coffee cups raw material requires two parts: the cup body and the bottom of the cup. The so-called cup body is the fan-shaped card that is die-cut in the front, and the bottom of the China paper coffee cups raw material is the paper rolls of different specifications cut out. The equipment used in the processing of these paper coffee cups raw material includes slitting machine, die cutting machine, (pre-press equipment also includes plate making and printing, etc.) printing machine and paper cup forming machine.
The cold drink cup in the China paper coffee cups raw material is directly printed, die-cut, and molded from the base paper, and then the surface is sprayed with food wax. The production process of the hot drink cup is that the China paper coffee cups raw material is coated and then printed and processed, and can not be coated with wax, because the heat may cause the wax to melt, which is harmful to the body.
