Paper cup making process

2022-03-25

　　1. Try not to design and use full-color paper cups. The ink of the full-color paper cups is too heavy, and the paper cups are directly sealed and packaged after production. The organic compounds emitted during the drying process of the solvent ink, the isopropyl alcohol in the alcohol wetting solution, and the volatile gas of the glazing paint are all harmful to human health. In a sealed space, the background color of the full version of the paper cup covers the entire body of the cup. Near the mouth of the cup, when we use the paper cup to drink water, our lips will touch a certain position of the mouth of the cup, and it is easy to bring the above-mentioned various chemicals into the liquid together with the The body affects the health of the body. Therefore, we generally recommend that customers should not design full color when designing and making paper cups, and the smaller the color block, the better. It is also not suitable to design graphics near the mouth of the cup, otherwise it will have the same bad effect.
　　2. For the bar near the bottom of the cup, the text design should be raised by 5mm. Because after the cup pieces are put on the machine, the bottom 5mm of the cup should be pressed to ensure the firmness of the bottom of the cup. However, the high temperature and pressure of the machine can easily make the graphics and text near the bottom of the cup smudged, affecting the appearance. Therefore, when designing and making graphics, the text and bar patterns near the bottom of the cup should be raised by about 5mm according to the height of the bottom of the cup. It can be avoided unless a special ultrasonic paper cup forming machine is used.
　　3. Don't use cheap and low-quality paper cups. Now there are many manufacturers producing paper cups, but few can really think about customers. We can see paper cups with a unit price of about 4-5 cents in the market. The quality of such paper cups is very poor, and the profit of the manufacturer is indeed very limited, even as low as 0.50-1.00 per box of goods (2000 pieces). Yuan. It is questionable whether hygiene and quality can be ensured at every step of production. .And the paper used in the paper cup is very thin and the body of the cup is easily deformed, and the hot water will be hot. There are great security risks.
　　4. Regular manufacturers are obliged to provide customers with the product hygiene inspection report provided by the national health department in the current quarter to ensure the hygiene of paper cups.
　　5. Distinguish between cold drink cups and hot drink paper cups. They "perform their respective functions", and once "misplaced", they will threaten the health of consumers. The surface of the cold drink paper cup should be sprayed or dipped in wax. When the temperature is between 0 and 5 degrees, this wax is very safe, but if it is used to hold hot drinks, as long as the temperature of the water exceeds 62 degrees, the wax will melt, and the paper cup will melt. Water absorption and deformation. The melted paraffin wax has a high impurity content, especially the polycyclic fenjing organic compound contained in it is a possible carcinogenic substance. When it enters the human body with beverages, it will endanger human health. The surface of hot drink paper cups will stick to A layer of special film recognized by the state, not only has good heat resistance, but also is non-toxic. Paper cups should be stored in a ventilated, cool, dry and pollution-free space, and the storage period should generally not exceed two years from the production date.
　　6. Choose a brand of paper cup factory products. There are many paper cup manufacturers in the market who do not actually have their own production bases, but instead sell paper cups by looking for other paper cup manufacturers. In this way, customers may also buy high-quality paper cups from them, but if there is a problem, the middleman is often unable to provide a solution, because it is impossible for the middleman to control the entire production process. This is easy to bring a lot of trouble to yourself, especially the company's customers. A good way to distinguish whether it is a direct manufacturer is to ask for its own business license and production hygiene license.
　　7. The problem of paper cups leaking. The production of paper cups is all assembly line production, and the number of units required by each customer is mostly tens of thousands or more. From an objective point of view, among tens of thousands of paper cups, it is inevitable that there are very few leaks. However, if the number of leaking paper cups exceeds the tolerable amount, the consumer can request the manufacturer to return the cup, and the manufacturer should unconditionally return it for the customer.
