The surface of the cold drink paper cup should be treated by wax spraying or dipping.

Because cold drinks will make the paper cup surface water, causing the paper cup to soften, it will be waterproof after being coated with wax. This wax is very stable and safe between 0 and 5°C. However, if the temperature of the beverage exceeds 62°C, the wax will melt and the paper cup will absorb water and deform when the beverage is used for hot drinks.
