Biographie A paper cup is a disposable cup made out of paper and often lined or coated with plastic or wax to prevent liquid from leaking out or soaking through the paper. It may be made of recycled paper and is widely used around the world. Originally paper cups were printed using rubber blocks mounted on cylinders, with a different cylinder for each colour. Registration across different colours was very difficult, but later flexography plates became available and with the use of mounting systems it became easier to register across the colours, allowing for more complex designs. Printing flexographic has become ideal for long runs and manufacturers generally use this method when producing over a million cups. Machines such as Comexi are used for this, which have been adapted to take the extra large reels that are required by paper cup manufacturers. Ink technology has also changed and where solvent-based inks were being used, water-based inks are instead being utilised. One of the side effects of solvent-based inks is that hot drink cups in particular can smell of solvent, whereas water-based inks have eliminated this problem. Other methods of printing have been used for short runs such as offset printing, which can vary from anything from 10,000 to 100,000 cups. Offset printing inks have also been developed and although in the past these were solvent based, the latest soya-based inks have reduced the danger of cups smelling. The latest development is Direct-printing, which allows printing on very small quantities, typically from 1,000 cups, and is used by companies including Brendos Ltd offering small quantities in short lead times. Rotogravure can also be used, but this is extremely expensive and is normally only utilised for items requiring extremely high quality printing like ice cream containers.

The paper cup machine is a kind of paper container made by mechanical processing and bonding of the base paper (white cardboard) made of chemical wood pulp. With the characteristics of safety, health, lightness and convenience, it is an ideal equipment for public places, restaurants and restaurants. The equipment has a heating station to heat the PE film on the surface of the PE-coated paper and compact it through the side and bottom pressing mechanisms. After cooling, the effect of firm bonding can be achieved.

The paper bowl is a kind of paper container made by mechanical processing and bonding of the base paper (white cardboard) made of chemical wood pulp, and its appearance is bowl-shaped. A kind of paper container made by mechanical processing and bonding of base paper (white cardboard) made of chemical wood pulp, with a bowl-shaped appearance. Waxed paper cups for frozen food, can hold ice cream, jam and butter, etc. Paper cups for hot drinks are coated with plastic, resistant to temperatures above 90¡ãC, and can even bloom with water. The characteristics of paper bowls are safe, hygienic, lightweight and convenient. It can be used in public places, restaurants, and restaurants, and is a one-time item. Since the advent of paper bowls, it has quickly become the most viable green tableware in the 21st century. Internationally renowned fast food chains such as McDonald's, KFC, Coca-Cola, Pepsi and various instant noodle products have adopted disposable paper bowls. A hygienic feature is the composition of the inner walls of the paper bowl. The reason why the paper bowl can hold water is that the inner wall of the paper bowl is coated with a layer of polyethylene water-repellent film. However, if the selected material is not good or the process is not good enough, this substance may be oxidized to its volatile carbonyl compound. This substance has a strange smell, and long-term intake of this substance is very harmful, especially some small factories are still using the prohibited recycled polyethylene water barrier film. Another hygienic property of paper bowls is its degradability. An industry insider said that paper bowls not only consume resources, but also impose a great burden on the environment. Moreover, due to the convenience of paper bowls, some people throw them away after use, which not only destroys the appearance of the city, but also brings great pressure to the sanitation work. Therefore, when choosing paper bowls, we must choose paper bowls made of degradable materials, and dispose of them properly after use.

Fully automatic single-sided PE coated paper bowl machine is a multi-station automatic forming machine.
It automatically feeds paper (printed fan-shaped paper), seals (heat seals the wall of the paper cup), fills oil (lubricates the upper roll), punches the bottom (automatically punches the bottom of the cup from the roll paper), heats, continuous processes such as knurling (sealing at the bottom of the cup), crimping, and unloading and collecting, as well as photoelectric detection, fault alarm, counting and other functions, are used for the production of beverage paper cups, tea paper cups, coffee paper cups, advertising paper cups and market paper cups, ice cream paper cups or other ideal equipment for disposable cone-shaped food paper containers. Paper cups, paper bowls and paper lunch boxes are the most vital green tableware in the 21st century.

Since its inception, paper tableware has been widely promoted and used in developed countries and regions such as Europe, America, Japan, Singapore, South Korea, and Hong Kong. Paper products are unique in appearance, environmental protection and hygiene, oil and temperature resistance, etc., and are non-toxic and tasteless, with good image, good feeling, degradable and non-polluting. As soon as paper tableware entered the market, it was quickly accepted by people with its unique charm. International fast food and beverage suppliers such as McDonald's, KFC, Coca-Cola, Pepsi and various instant noodle manufacturers all use paper tableware. The plastic products that appeared 20 years ago and were known as the "white revolution" brought convenience to human beings, but also produced "white pollution" that is difficult to eliminate today. Because plastic tableware is difficult to recycle, incineration produces harmful gas, and it cannot be degraded naturally, and burying will damage the soil structure. Our government spends hundreds of millions of dollars every year to deal with it with little success. The development of green products and the elimination of white pollution has become a major global social issue. At present, from an international point of view, many countries in Europe and the United States have already legislated to prohibit the use of plastic tableware. From the domestic situation, the Ministry of Railways, the Ministry of Communications, the State Environmental Protection Administration, the State Planning Commission, the Ministry of Science and Technology, and local governments such as Wuhan, Hangzhou, Nanjing, Dalian, Xiamen, Guangzhou and many other big cities have taken the lead in promulgating decrees to completely prohibit the use of disposable For plastic tableware, the No. 6 document of the State Economic and Trade Commission (1999) also clearly stipulates that at the end of 2000, the use of plastic tableware will be banned nationwide. A global change in the plastic tableware manufacturing industry is gradually emerging. The green environmental protection product of "replacing plastic with paper" has become one of the current social development trends.
