Disposable paper cup production process: base paper coating - cutting - sample layout - Printing - film cutting - Disinfection - molding - disinfection packing - warehousing. First is the width of the paper, according to the printing plate face and way to determine. Either slitting or die cutting, followed by printing. There are two kinds of offset printing and rubbing printing. Next is die-cutting, which is to cut the printed paper into fan-shaped pieces. What's more, some advanced machines can die-cut themselves. The last part is molding, which needs two parts: body and bottom.
Disposable paper cup
The so-called cup body is the fan-shaped film cut out in front of the cup, and the bottom of the disposable paper cup is the paper roll cut out of different specifications. There are four kinds of machines in the four processes of slitting [crosscutting] printing, die-cutting and molding. There is an auxiliary resource in the operation of four kinds of machines, that is, compressed air. Equipment: Slitter, die-cutting machine, (pre press equipment: plate making, plate printing,) printing machine, paper cup forming machine.
The production process of the disposable paper cup cold drink cup is that the paper cup base paper is directly printed, die cut, shaped and processed, and the surface is sprayed with food wax. The production process of the hot drink cup is that the paper cup base paper is coated into the paper cup paper, printed, die cut and shaped. The hot cup needs to be coated with film and cannot be coated with wax, because the heat may cause the wax to melt, which is harmful to the body, which is the difference. The paper cup paper printing adopts the flexible water-based ink. For raw paper, many paper manufacturers provide printing and die-cutting services, so when they start to invest in the establishment of paper cup and paper bowl manufacturers, they can directly purchase the printed die-cut paper cup pieces. Because the cost of printing and die-cutting in the production of paper cups and bowls accounts for a small proportion of the cost, the cost is mainly determined by the size and weight of paper cups.
