The double-layer paper cup, as its name implies, means that the paper cup is double-layered and has two layers. The quality of double-layer paper cups is better than that of single-layer paper cups. The use time of double-layer paper cups is also longer than that of single-layer paper cups. It can also be used to hold hot beverages, such as hot coffee.
Material of Double-Wall Paper Cup:
Double-Wall paper cups are made of food grade wood pulp paper plus food grade PE film.
Development History of Double Wall Paper Cup:
In order to expand the application range of paper cups, in 1940, straight-walled double-layer cups were introduced to the market. This paper cup is not only easy to carry, but also can hold hot beverages. Afterwards, the manufacturer applied latex to these paper cups to cover the taste of the paper cup material, and to strengthen the leak-proofness of the paper cups. The single-layer wax-coated cups that have been coated with latex are widely used to hold hot coffee. .
Application of Double Wall Paper Cup:
At present, most of the cold drink paper cups are double-coated, and a small amount of internal coating is used. Cold drinks usually add ice cubes. Even if the ice is deiced, the drink itself will be cooler than the outside temperature, which will form condensation on the outside of the paper cup. Single-coated paper cups will cause the cup paper to overabsorb water and become soft, which affects the customer experience. Therefore, most cold drink paper cups will consider using double coating.
