What Material Is The Disposable Soup Cup

The general raw materials of the disposable soup cup are: food-grade wood pulp paper + food-grade PE film.

Disposable paper cold drink cups are paper cups that can hold cold drinks. Cold drinks have a characteristic and need to be frozen or refrigerated. The safe use temperature is 0°C-5°C. It is determined that the paper cup as a whole can be waterproof. The body of the cold drink cup is made of food-grade wood pulp paper + pe film on the inner and outer surfaces. This can effectively prevent wood pulp paper from losing its original stiffness and toughness due to exposure to moisture.

In order to achieve the water barrier effect in the production of paper cups, a layer of polyethylene water barrier film will be coated on the inner wall. Polyethylene is the safest chemical in food processing. However, if the selected material is not good or the processing technology is not good enough, the polyethylene may be oxidized to carbonyl compounds during the process of hot melting or applying to paper cups. Carbonyl compounds are not easy to volatilize at room temperature. When hot water is poured into the paper cup, they may volatilize, so people will smell strange.
