With the rapid development of China's economy, disposable paper cups have become essential daily necessities for homes, restaurants, offices, etc. Its changeable shape, bright colors, and not afraid of being beaten, are loved by many people. The paper cups currently sold on the market are generally made of single-layer paper in structural design. Generally, the paper cups have low strength, and the cup body is prone to deformation after containing hot water, and the heat insulation effect is poor and does not prevent slippage. The following editor introduces the function of double-layer paper cups.
Single-layer paper cups are one of the disposable paper cups, also known as single-sided coated paper cups. The single-layer cup with a smooth pe-coated layer inside the paper cup is generally used to hold drinking water, which is convenient for people to drink. The raw materials of the house are made of food grade wood pulp paper + food grade PE film. 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.
In order to expand the application range of paper cups, in 1940, straight-walled double-layer paper cups were introduced to the market. This paper cup is not only easy to carry, but also can hold hot beverages. Later, 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 cup. The single-layer wax-coated cup after latex coating treatment is widely used for holding hot coffee. . A double-layer paper cup includes a base and a double-layer paper cup body composed of an inner paper cup body and an outer paper cup body. The inner or outer surface of each paper cup body is provided with uneven reinforcing ribs. The composed surface is a concave-convex surface, and the inner paper cup body and the outer paper cup body are sealed and adhered to each other.
