Paper bowl is a common container in our lives. Because it will come into contact with our food, its safety is a concern of every consumer.
So how does the paper bowl machine ensure the safety of the paper bowl during the production process? In fact, if we observe carefully, we can find that the inner surface of the paper bowl we often use has a reflective film.
This layer of material is a polyethylene water barrier film. Each paper bowl machine must ensure the existence of this film during the production process. However, according to the different materials used and the gap in the use process, many inferior paper bowl machines produce this layer of film. Under the action of air, it is easily oxidized into a compound harmful to the human body.
Therefore, in the paper bowl machine industry, this film-adding process is generally called the soul of the paper bowl machine production process.
