The material of glass itself comes from nature. After high temperature, harmful substances have been volatilized during the production process. It has high safety, high temperature resistance and good thermal conductivity, so it is suitable for microwave cooking.
But there are also disadvantages: fragile. In addition, if used improperly, it is easy to cause bursting; The glass dining box is clean and sanitary, and does not contain toxic substances. However, the glass dining box can sometimes become "moldy" because the glass is eroded by water for a long time. The sodium silicate in the glass reacts with the carbon dioxide in the air to form white carbonic acid crystals, which is harmful to human health. Therefore, alkaline detergent can be used to remove it.
Compared with this natural glass lunch box, the plastic lunch box may be more uncertain in terms of safety performance, not to mention that the plastic material itself is "unhealthy", let alone that it is used to contain edible food. However, whether there is a danger and whether the glass lunch box is better than the plastic lunch box depends on how to use it.
As mentioned above, the use of glass lunch boxes is more suitable for office workers to bring meals, which is also considered that they can be cooked in microwave ovens; The plastic lunch box can only be used for "loading". The temperature of food can't be too high when loading food. If the temperature is too high, the "unsafe" factors in the plastic material can't be controlled.
