Its exquisite appearance makes people love it even more. It can incarnate into a fashionable simple shoulder bag and become a beautiful scenery on the street.
Han Yongsheng, member of the Packaging Committee of the association, introduced that the paper cups sold in the market are mainly divided into normal temperature paper cups and high temperature paper cups.
The inside of the normal temperature paper cup is coated with a protective layer of candles, which can be used to prevent leakage, but this kind of cup is not comfortable to hold hot drinks such as tea and coffee. Polyethylene (PE) is used inside the disposable coffee cup to withstand the high temperature below 100 ℃. According to Han Yongsheng, the paper cups sold in the market have a wide range of problems, such as unclear identification and poor packaging, which is due to the low manufacturing cost of the paper cup industry
The industry threshold is not high.
Therefore, it is suggested that we choose the paper cup products with well-designed packaging, use the paper cup accurately, and try our best to reduce the use of disposable paper cup, which can not only reduce the possibility of contacting unsafe things, but also reduce the pollution and consumption of disposable products.
