According to national regulations, disposable paper cups "cannot be artificially added with fluorescent whitening agent". Disposable paper cups are divided into cold drink cups and hot drink cups according to their purpose. Once misused or misused, it will affect the health of the body. The raw material for the waterproof layer of the disposable paper cup is polyethylene. Inferior paper cups are made of recycled polyethylene, which will produce many harmful substances in the process of processing and production. The paper cup is coated with a layer of polyethylene water-proof film on the inside to achieve the water-proof effect.
The surface of the cold drink paper cup needs to be soaked or waxed to achieve a waterproof effect. After the water temperature exceeds 62 degrees, the stability of the wax weakens and the paper cup becomes soft. Among them, the potentially carcinogenic substances will be ingested by the human body along with water. The surface of the hot drink cup is a special polyethylene film approved by the country, which has good heat resistance and is non-toxic.
In addition, there are also specified standards for the thickness and permeability of disposable paper cups. The bottom and sides of the water cup must not be water-permeable or permeable, and the paper quality must not be too soft.
