The Hygiene Performance Of Paper Bowls

The second hygiene performance is the composition of the inner wall of the paper bowl. The reason why paper bowls can hold water is because a layer of polyethylene waterproof film is coated on the inner wall during the production of paper bowls. However, if the material used is not good or the process is not up to standard, this substance may oxidize into highly volatile carbonyl compounds. This substance has a strange odor, and long-term intake of this substance is very harmful, especially when some small factories are still using banned recycled polyethylene waterproof films.
The third hygiene performance of paper bowls is their biodegradability. An industry insider said that paper bowls not only cause resource consumption, but also impose a great burden on the environment. Moreover, due to the convenience of paper bowls, some people throw them away casually after use, which not only damages the appearance of the city, but also brings huge pressure to environmental sanitation work. Therefore, when choosing paper bowls, we must choose biodegradable materials and dispose of them properly after use.
