The Earliest And Most Basic Use of Double Wall Paper Cup

1. The biggest function of Double wall paper cup is to hold drinks, such as carbonated drinks, coffee, milk, cold drinks, etc. This is its earliest and most basic use. Paper cups can be divided into cold cups and hot cups. Cold cups are used to hold cold drinks, such as carbonated drinks and iced coffee; Hot cups are used to hold hot drinks, such as coffee and black tea. Distinguishing between cold drink cups and hot drink paper cups, they "perform their duties". Once they are "misplaced", they will threaten consumers' health. The surface of cold drink paper cups should be treated by spraying wax or dipping wax. Because cold drinks can accumulate water on the surface of paper cups, which leads to softening of paper cups, they can be waterproof after being coated with wax. This wax is very stable and safe at 0~5℃. However, if it is used for 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 melted paraffin has high impurity content, especially the compounds contained in it, which may cause cancer, and will harm people's health when entering the human body with the drink. A special polyethylene film recognized by the state will be stuck on the surface of hot drink paper cups, which is not only heat resistant, but also non-toxic under high temperature immersion. Paper cups should be stored in a ventilated, cool, dry and pollution-free space, and the storage period should generally not exceed two years from the production date. 2. Advertisers or manufacturers also use double wall paper cup as an advertising medium. The design on the cup can give people a different drinking mood, and it is also a "symbol" to promote a certain product. Because the trademark, name, manufacturer, distributor, etc. of the product can be designed on the surface of the paper cup. When people drink beverages, they can know and understand products from these information. Paper cups provide a platform for people to understand these new products.
