The history of paper cup history has gone through four stages:
Conical/pleated paper cups were originally introduced in a conical shape, made by hand, glued together, easier to separate, and must be used as quickly as possible. Later, the folded paper cups were pleated on the side walls to increase the strength of the side walls and the durability of the paper cups, but it was more difficult to print the patterns on these folded surfaces, and the effect was not satisfactory.
Wax paper cup
In 1932, the first wax-coated two-piece paper cup came out, and its smooth surface could be printed with various exquisite patterns to enhance the promotion effect. The paper cup is coated with wax, which can avoid direct contact between the beverage and the paper, and can protect the adhesiveness of the adhesive and enhance the durability of the paper cup; on the other hand, the thickness of the side wall is increased, so that the strength of the paper cup is greatly improved, thereby reducing Reduce the cost of production by making the amount of paper necessary to make a stronger paper cup.
As waxed paper cups become containers for cold beverages, one would also like to use a convenient utensil to hold hot beverages. However, the hot beverage melts the wax layer on the inner surface of the paper cup, and the glue bonding port separates. Therefore, the general wax coated paper cup is not suitable for holding hot drinks.
