Can Glass Fresh-keeping Boxes Be Placed in The Freezer?

Glass fresh-keeping boxes cannot be placed in the freezer. Because glass fresh-keeping boxes are made of glass, they are fragile and will explode after being exposed to the low temperature of the refrigerator. There are three types of fresh-keeping boxes. One is a plastic fresh-keeping box: made of resin material, generally with a temperature range of up to 120°C and a minimum temperature of -20°C. One is a tempered glass fresh-keeping box: ordinary glass is tempered. The last one is a heat-resistant glass fresh-keeping box, which is made of high borosilicate glass and is currently recognized as a good fresh-keeping box. As consumers pay more and more attention to health, people are more concerned about whether the materials used in the fresh-keeping box itself are healthy.
