Ice bags are very useful for our life! So how can we know ice bags more scientifically? At present, there are two kinds of ice bags on the market, one is edible ice bag, the other is special ice bag for cold chain which is used to store all kinds of low-temperature goods. Today, we mainly come to know the special ice bag for cold chain. Although this kind of ice bag is environmentally friendly and non-toxic, it must not be eaten.

Ice bags are commonly known as:

Ice bag, commonly known as ice source, refrigerant, storage agent or refrigerant in the cold chain industry.

Contents of ice bag:

Although there are different names for ice bags, their components and working principles are the same. The contents of ice bags are a kind of efficient refrigerant, safe, environmental friendly, non-toxic and tasteless.

Ice pack:

Generally, the packaging of ice bags is nylon composite film and PE film (Note: the strength of nylon composite film is higher than that of PE film, but the cost is higher. Generally, regular ice bag manufacturers will use nylon composite film, such as Suzhou ante industry).

Practical use characteristics of ice bags:

After freezing, the ice bags will not leak in the actual transportation environment and will not pollute the transportation goods. In use, it is not limited by transportation conditions and geographical restrictions.

Ice bag type:

The types of ice bags include water filled ice bag, non water filled ice bag (finished ice bag), solid ice bag, biological ice bag, etc.

Ice bag temperature area division:

Ice bags can be divided into 2-8 ℃ refrigerated ice bags, - 12 ℃ / - 18 ℃ / - 22 ℃ refrigerated ice bags, - 36 ℃ / - 55 ℃ dry ice bags.

Normal temperature and freezing state of the contents of ice bags:

The normal temperature state of the contents of the ice bag is different according to the type of ice bag. The water injected ice bag is in the white powder state before use, in the paste granular state after water injection, and in the solid state after cooling; the non water injected ice bag is the finished ice bag, in the paste granular state under normal temperature, and in the frozen state; the solid ice bag is in the solid state at normal temperature and after freezing; the biological ice bag is in the jelly state under normal temperature, and in the frozen state. Solid state

Working principle of ice bag:

The working principle of ice bag is to absorb a large amount of energy from the outside and release it slowly and stably to achieve the effect of heat preservation and cold preservation. The whole process belongs to the physical change process energy conversion, which does not produce any chemical toxic substances.
