Problems solved by technology

[0002] Tableware is used to hold food, it is in close contact with food, and is closely related to human health. Although it is often cleaned, if the internal quality of the tableware is poor, it will also have a negative impact on people's health; there are many kinds of materials on the market. Tableware, some tableware contains certain harmful substances. After contact with food, the harmful substances will enter the food and damage human health; ceramic or enamel tableware, the glaze pigment contains harmful metals, and the enamel contains lead silicate and the like. compounds; wooden tableware has stable chemical properties, but is not easy to clean, and is prone to mildew and insects; in recent years, plastic tableware with melamine-formaldehyde resin as the main raw material When using food or water, some harmful substances will seep into the food or water, and the scope of use is also greatly limited; in recent years, plant fiber tableware has been widely used, and this tableware is easy to degrade and will not pollute the environment; however, plant fiber tableware has a short service life. Not durable, easy to break, and poor antibacterial performance
