Disposable paper cup production process: base paper coating---cutting---typesetting---printing---film cutting---sterilization---forming---sterilization and packing---warehousing . The first is to deal with the width of the paper, which is determined according to the facing and method of the printing plate. Either slit or die cut, followed by printing. There are two types of printing: offset printing and kneading printing. The next step is die-cutting, which is to cut the printed paper into fan-shaped sheets. It should also be said that some advanced machines can die-cut by themselves. The last step is molding, which requires two parts: the cup body and the bottom of the cup.

There is a saying that disposable paper cups are easy to spread, that is, the inner layer of paper cups contains paraffin, which will melt when filled with hot water, and will be harmful to the body when deposited in the stomach. In fact, the disposable paper cups themselves are divided into two types: one is for "cold water cups", which is indeed waxy; the other is for "hot water cups", also known as film-coated cups, the inner wall is still a layer of polyethylene The melting point of PE-coated plastic film is much higher than that of wax, which is 80°C ~ 130°C, so compared with wax, it can be ideally used to hold hot beverages.

The so-called cup body is the fan-shaped piece that is die-cut at the front, and the bottom of the disposable paper cup is the paper rolls of different specifications cut out. Slitting [cross-cutting] printing, die-cutting, forming, there are 4 kinds of machines in the 4 processes, and there is an auxiliary resource in the operation of the 4 kinds of machines, that is, compressed air. The equipment includes; slitting machine, die-cutting machine, (prepress equipment: plate making, printing plate,) printing machine, paper cup forming machine.

The raw materials for making paper cups are super-large rolls of harder and slightly thicker paper rolls. Although the diameter of the paper roll is only 1 meter, the paper length is 5,000 meters, and the super-large roll with a weight of one ton can be made into 250,000 paper cups.

A very simple example: I have mailed teaching materials after graduating from college. The density of books and paper is high, and the stacks are overweight, and the courier fee is astonishing... Therefore, the factory is generally directly computer-controlled for transportation, and there is very little manual handling. Effort is also prone to danger.

The production process of the disposable paper cup cold drink cup is direct printing, die cutting, molding processing, and spraying food wax on the surface of the paper cup base paper. The production process of the hot drink cup is that the paper cup base paper is coated into paper cup paper, printed, die-cut, and processed. Hot drink cups need to be coated, not waxed, because the heat may cause the wax to melt and be harmful to the body, that's the difference. The paper cup paper is printed with flexographic water-based ink. For raw paper, many paper manufacturers provide printing and die-cutting services, so when you first invest in the establishment of paper cups and paper bowls, you can directly buy the printed and die-cut paper cups. Because the cost of printing and die-cutting does not account for a small proportion of the cost in the production of paper cups and paper bowls, the cost is mainly determined by the size of the paper cup and the weight of the paper.
