The emergence of new technologies and processes has continuously improved the manufacturing technology of paper cups, and new types of paper cups will appear and play a greater role in promoting the variety of products.

The surface of cold drink paper cups should be treated with wax spraying or soaking wax. Because cold drinks will cause water on the surface of the paper cup, the paper cup will soften, and it will be waterproof after being coated with wax. The wax is very stable and safe when it is between 0～5℃.

So, is the larger the weight of paper, the more it can increase the thermal insulation and compressive strength of the corrugated cup? actually not. To enhance the thermal insulation and compressive strength of the corrugated paper cup, the thermal insulation capacity of the outer cup must be enhanced. As long as there is no trace of corrugation after the surface paper is pasted, the paper with lower weight can be used as much as possible; the core paper and corrugated paper are best Use straw pulp or wood pulp paper with good stiffness and high ring compressive strength.

But if it is used to hold hot beverages, as long as the temperature of the beverage exceeds 62℃, the wax will melt, and the paper cup will absorb water and deform. The melted paraffin wax contains high impurities, especially the polycyclic then hydrocarbon organic compounds contained in it, which may be carcinogenic. Substances that enter the human body with beverages will endanger human health. A special polyethylene film will be glued to the surface of the hot drink paper cup. It has a good heat resistance and is non-toxic when immersed in high-temperature beverages.
