1. A great function of paper cup is to hold drinks, such as carbonated drinks, coffee, milk, cold drinks, etc., which is its earliest and most basic use.
Beverage paper cup can be divided into cold cup and hot cup. A cold cup is used to hold cold drinks, such as carbonated drinks and iced coffee; a hot cup is used to hold hot drinks, such as coffee and black tea.
Distinguish between cold drink cup and hot drink paper cup, they "perform their own duties", once "dislocation", will threaten the health of consumers. The surface of cold drink paper cup should be treated by wax spraying or dipping. Because the cold drink will make the paper cup surface ponding, resulting in paper cup softening, coated with wax can be waterproof. The wax is very stable and safe in the range of 0-5 ℃. However, if it is used to hold hot drinks, as long as the temperature of the drink exceeds 62 ℃, the wax will melt, and the paper cup will absorb water and deform. The content of impurities in the melted paraffin is high, especially the organic compounds of polycyclic aromatic hydrocarbons contained in it. It is a kind of carcinogenic substance, and it will harm people's health if it enters the human body with the drink. The surface of the hot drink cup will be pasted with a layer of special polyethylene film approved by the state, which is not only heat-resistant, but also harmless when soaked in high-temperature drinks. The paper cup should be stored in a ventilated, cool, dry and pollution-free space, and the storage period should not exceed two years from the date of production.

When people drink drinks, they can know and understand the products from the information. The paper cup provides a platform for people to understand these new products.
