Cup History
After the United States, Laurence invented the pure water vending machine, in order to solve the problem of pure water vending machine used in the fragile ceramic cup, the younger brother of the invention of the paper cup, Laurence.
Cone / pleated paper cup
The original paper cups are conical, made by hand, glue to glue, easy to separate, it must be used as soon as possible. The folding cup, which was later developed, was folded in the side wall to increase the strength of the side wall and the durability of the cup, but it would be difficult to print the pattern on the surface of the pleats, and the effect was not ideal.
Coated paper cups
In 1932, the first two pieces of wax coated paper cups came out, its smooth surface allows the printing of a variety of beautiful patterns, improve the effectiveness of the promotion. On the one hand can be waxed paper cups, avoid direct contact with the beverage and paper material, but also can protect the adhesive glue, enhance the durability of the cup; on the other hand also increased the thickness of the side wall, the paper strength greatly improved, thereby reducing the manufacturing to stronger cups required paper consumption of raw material, reduce production cost the overall production efficiency can be improved.
With the use of wax coated paper cups as a popular drink for cold drinks, people also hope to use this convenient utensils to carry hot drinks, such as hot coffee, hot tea, etc.. However, the hot drinks will melt the wax layer on the inside surface of the paper cup and mix with the beverage, thus affecting the flavor and appearance of the beverage. On the other hand, the wax layer is melted, adhesive stoma would fall apart. Therefore, the general wax coated paper cups are not suitable for hot drinks.
Double wall cup
In order to expand the scope of the application of paper cups, 1940, straight wall double cup (straightwalldoublewrapcup) market. The paper cup is not only convenient to carry, but also can be used for holding hot drinks. Since then, manufacturers are more in these cups coated with emulsion (latexsolution), to cover the paper with a "cardboard flavor", and enhance the leakage of paper cups. Single layer wax coated glass (singlewrapwaxcup), which has been treated with latex coating, has been widely used in vending machines to hold hot coffee.
Polyethylene coated paper cups
When people are using a latex coated paper cups filled with hot drinks at the same time, the food companies have begun to use polyethylene coated paper board to increase the barrier and tightness of paper packaging. Because the melting point of the polyethylene is much higher than that of the wax, a novel beverage paper cup coated with the material can be used for carrying the hot beverage, and the problem of the product quality due to the melting of the coating material is solved. At the same time, polyethylene coating smoother than the original wax coating, improve the appearance of paper cups. In addition, the processing technology is also cheaper and faster than the use of latex coating method, while reducing production costs, production efficiency can also be improved. On the other hand, it can be used to hold the characteristics of cold and hot drinks, so that the scope of application of paper cups can be further widened.
In fact, polyethylene coated beverage cups just came out, due to the slow production rate, high cost of raw materials, the price is higher than other natural paper cups. With the continuous improvement of molding technology, now the paper cup molding speed has been as high as 125 to 240 minutes / minute, combined with the heat sealing material cost down, so that the production cost can be greatly reduced. More importantly, the world's largest paper cup users - the international fast food industry, such as McDonald's, has decided to increase the use of polymer coated paper cups, reducing the use of coated paper cups. On the other hand, in the past few years, the size of fast food cups tends to be large enough to encourage customers to buy more drinks. However, the large wax coated paper cups are not as durable and strong as the heat sealing paper cups, and the printing effect is not as clear as the heat sealing paper cups. Therefore, whether in terms of durability or promotion, polyethylene coated paper cups are better than wax coated paper cups. We believe that this new type of beverage cup will eventually replace the double layer of wax coated paper cups and latex coated paper cups, its development prospects.
Today, the scope of application of paper cups more and more widely. In addition to cold and hot drinks, polyethylene coated paper cups are a popular container for ice cream and frozen yogurt. In the United States and the Far East, the use of paper cups in soups and other foods is also increasing. In addition, straight wall cup (round cardboard cup) is also widely used in ice cream, raisins, Li Gan and grains and other packaging. With the convenience of the people to eat more and more urgent, beverage cups with its convenience, aesthetics, the advantages of disease prevention, will become the darling of the generation of drinking water.
