Can the high borosilicate glass lunch box be frozen for a long time?

Many kitchen supplies can be frozen. However, can the glass lunch box be placed in the freezing box? The glass lunch box requires a special high borosilicatea glass for a long time. High borosilicateon glass is a special glass. It is usually silicon, oxygen, and oxygen, and Boron composition. Due to the high content of boron, high borosilicatea glass is also called borosilicateate glass. Compared to traditional glass, high borosilicatea glass has better heat resistance and chemical resistance. In addition, its production cost is relatively high. So, can high borosilicate glass be frozen for a long time?

In fact, high borosilicatea glass has very good temperature resistance. It can withstand high temperature changes, which is extremely tolerant to the environment in the ordinary frozen library below -18 ° C. Compared with this, ceramic or glass products can easily break when temperature changes. Therefore, high borosilicatea glass can also be placed in a low -temperature frozen library, and can also act as a container for long -term freezing food.

At the same time, when using the fresh -keeping box/container made of high borosilicatea glass, pay attention to a few points to better use the freezing characteristics of this material:

In order to ensure completely sealing, it is recommended to use vacuum packaging to make or improve the sealing performance.

During use, avoid violence or vibration.

Do not be too long when the food cooling before freezing, to reduce the potential factors of condensation, causing the probability of cracking during freezing and ensuring sufficient heat resistance.

In general, high -borosilicatea glass, as a thermal and chemical stability glass that is generally used in laboratories, restaurants and other fields, has undergone the test of long -term freezing. Therefore, you can use the high -borosilicate glass fresh -keeping box in a container for long -term frozen food.
