Only in a moment! Now let me introduce the forming process of the paper cup
First of all, the paper used to make paper containers must be food grade paper. Most of the food grade paper is imported from Europe and America, which is the best grade among the paper materials. Then, it is necessary to coat the paper surface with oil-water resistant material through the process of coating before the continuous forming step can be carried out.
Coating is to attach a thin layer of plastic material on the paper, so that the paper cup can be resistant to oil and water, and can hold drinks and soup food for a long time. The selection of this coating material is also related to the characteristics of subsequent paper cups. This is the step to make the cup strong and beautiful.
After coating, the required pattern and color will be printed on the paper roll. Printing methods can be divided into gravure, convex plate and flat plate. The cost of gravure is too high, so it is seldom used now; Convex plate printing is continuous printing on paper roll, which requires a large amount of printing. In lithography, the paper is cut into pieces and then printed, which is suitable for manufacturing small quantities of products. After the ink is finished, a layer of water gloss treatment will be printed for protection.
Some manufacturers use the method of "printing in ink", printing first and then coating, and coating the ink in the coating. This method has higher consumption rate and higher cost. However, no matter what kind of printing method, the container printing materials in contact with food must be food grade to ensure the safety of food.
The printed paper enters the knife mold to make fan-shaped pieces of paper, that is, the unfolded shape of the wall of the paper cup. These fan-shaped pieces of paper are collected and sent to the forming machine, and then the paper is rolled into a paper cup shape outside the cup mold. At the same time, the mold provides heat at the seams of the paper, so that the PE is thermally damaged and bonded to each other, and the bottom of the paper cup is then bonded. Next, the mold pushes the cup mouth, and the paper at the cup mouth is rolled down and fixed by heat, forming the cup edge of the paper cup. These molding steps can be completed in one second.
The finished paper cup is sent to the testing machine to confirm whether the shape is complete without damage and the internal surface is clean without stains. The finished paper cup will enter the packaging process and wait for shipment.

Is paper pipette more environmentally friendly than plastic one?
A: The pollution of plastic products to the environment is mainly due to the large use and low recovery value, so the recovery is small, easy to leak into the environment, which has an impact on marine life and environment. The paper straw is used as an alternative to solve this problem. Because the degradation rate of paper in natural environment is faster than that of plastic, the pollution to the ocean will be less if it leaks into the environment. However, there should be a standard for paper pipettes. Some are made of composite materials, such as paper + coating, and so on, their biodegradability will be discounted. Therefore, we suggest that we should use less straw if not necessary, whether it is paper or plastic. Before using it, ask yourself: am I not using it or not? Q: Is it not necessary to worry about pollution and use it without any control with degradable plastic straw? A: The raw material of degradable plastics is corn and other food crops. Uncontrolled use will cause food waste. In addition, the safety of degradable plastic components is not higher than that of traditional plastics. Many degradable plastic bags are easy to break and not durable. For this reason, some producers will add various additives, which may have a new impact on the environment. So instead of using degradable plastic products, reducing the use of disposable products may be a simpler and effective way to avoid side effects. Q: What about the poor quality of paper suction pipe? Is there any other solution? A: Plastic limiting is not used without plastic, but for disposable and health risk plastic products. If you have a lot of traditional plastic straw in your house, you can use them as durable goods for a long time, and save a paper straw for the tea shop. Plastic straw can be recycled, in fact, it is more environmental protection than the paper straw thrown once! Q: What kind of garbage does degradable plastics belong to after the classification of garbage is implemented? A: In Europe and America, under the condition that classified collection and composting are ensured at the back end, it can be classified as compostable garbage or can be put together with food waste. In the classification guide issued by most cities in China, it is not recyclable. Shanghai classified it as dry waste, and Beijing and other cities as other wastes. Therefore, some experts suggest that the promotion of degradable plastic products should not be carried out step by step, on the other hand, the construction of treatment capacity should be actively expanded.

The paper cup machine should not use disposable paper cup to fill the water as far as possible
Try not to use disposable paper cup to hold boiling water. In order to prevent water penetration, the inner wall of the paper cup is coated with a thin layer of wax. If the water temperature exceeds 40 ℃, this layer of wax will melt. Therefore,
