Paper bowls can hold water because a polyethylene waterproof film is coated on the inner wall during production. However, if inferior materials are used or the manufacturing process is substandard, this substance may oxidize into highly volatile carbonyl compounds. These compounds have a peculiar odor, and long-term intake is highly harmful, especially since some small factories still use prohibited recycled polyethylene waterproof films. The hygienic performance of paper bowls lies in their inner wall composition. The third hygienic aspect of paper bowls is their degradability. An industry insider stated that paper bowls not only consume resources but also place a significant burden on the environment. Moreover, due to the convenience of paper bowls, some people discard them carelessly after use, which not only damages the urban landscape but also creates immense pressure on sanitation efforts. Therefore, when choosing paper bowls, it is essential to opt for those made from degradable materials and ensure proper disposal after use. Xuzhou paper cup and paper bowl customization manufacturers supply products suitable for public places, restaurants, and dining establishments, as they are disposable items.
