What is a cooling pack?

A cooling pack is a biological product, a new freezing medium used to refrigerate items and maintain their low-temperature state. For the aviation ban on carbonated ice and must use dry ice, dry ice cannot be used repeatedly by the sea. Service cost, remote areas, difficulty buying dry ice and many other difficulties. The cooling bag can be used in aircraft aviation, can be used repeatedly at a low cost of use, and can be used as a refrigerator place and other obvious advantages in the use of cost, safety and convenience of many aspects are beyond dry ice, changing the low-temperature aviation distribution process both banning the use of dry ice, but also.

What's in the cooling pack?

Ice pack ice is mainly composed of polymer, water-absorbing resin. The content of the cold pack is made of cold capacity, a non-toxic, odorless polymer as the basic composition of raw materials. Its content is clear, non-corrosive, non-anti-radiation and elastic. The main material is CMC.

What is the cooling pack used for?

Cooling packs are used to preserve biological products such as vaccines, toxoids, immune preparations, insulin, serum, etc. Biological vaccines must be continuously refrigerated in all storage, transport and use aspects. Because biological vaccines are temperature sensitive, but they can fail due to high temperatures at every step between the department where they are manufactured and used. Therefore, to ensure that vaccines used in immunization programs are properly refrigerated throughout the entire process, from production, storage, transportation and distribution to use, vaccines are always kept under specified refrigeration conditions to ensure that the reasonable potency of the vaccines is not compromised.

Bio-ice is a new freezing medium formulated with high-tech biological materials, which is clean and non-toxic and does not pollute water during thawing and melting. In addition, its specific heat capacity is high, 3 to 4 times that of ice, so it has a good heat transfer and melting rate and good cooling performance and can be directly molded and reused.

Ice pack ice is also used for long-distance fresh refrigerated transport of biochemical reagents, tin paste, veterinary drugs, plasma, vaccines, aquatic products, ornamental fish, dairy products, meat products, agricultural products, flowers, vegetables, fruits etc.

The cool package can also be used for medical and antipyretic, patient fever cooling, anti-inflammatory and pain relief, cold beauty, sprains, falls, hemostasis, skin care, suppuration and another auxiliary physiotherapy.

Advantages of using the cooling pack

Unrestricted by airlines, trains, etc., it can be transported by planes and trains. The cooling pack has passed all kinds of aviation safety certifications, such as using an ordinary gel ice bag that can be used on aircraft. It completely changed aviation's low-temperature distribution process by prohibiting carbonized ice, but you also need to use dry ice in embarrassing situations. It is a revolutionary scientific research achievement of refrigeration of low-temperature transport goods.

Reusable and low cost of use The contents of the reusable pack are gelatinous and can be reused N times, saving costs, hot and cold dual use, large cold capacity, its cold source is released evenly and slowly (releases cold speed than ice 6 times slower), with a good time to keep cold, because the ice from the release of the cold will produce water spots, easy to moisten the goods and affect the quality, so the biological ice pack in the air cargo is widely used. Unlike carbonized ice as a one-time use, the use of huge costs, some low-temperature goods repeatedly transported back and forth, will undoubtedly greatly reduce the cost of use.

No geographic restrictions: The ice pack is unlike dry ice that can only be purchased in a major first-class city. As long as there are isolation boxes, foam boxes and cryogenic refrigerators, you can use the ultra-low temperature ice pack based on technology, which is revolutionary for cryogenic transport in remote areas and field sampling in research institutes.

Long heat retention time tested by independent institutions, the technological ice of instant ice packs is 6 times longer than regular ice of the same volume. As a result, it is widely used in preserving and distributing vaccines, diagnostic reagents, blood, low-temperature food and other goods that require freezing and refrigeration.

Types of the cooling package

Reusable ice pack

The reusable ice pack consists of two non-woven textile layers, which combine a secret trade formula and compresses in a special form of cross-linked polyacrylic polyol polymeric refrigerant. Inside, two key layers of plastic use a unidirectional, finely perforated technology that allows the plastic layers to be bonded to the textile layers, ensuring that this new model can withstand the harshest weather conditions during transport.

Disposable cooling pack

Disposable cooling packs are made of two sides. One is high-density plastic, and the other is non-woven.

Mainly used for perishable products, biological agents and all products that require refrigerated transport (if they are transported with the product and cannot be recovered for reuse, it is recommended to use disposable ones). Although they are designed for single use, they can be used several times under careful use.

A medical ice pack is a kind of disposable cooling pack, which is mainly used for medical fever cooling and pain relief, antipyretic, anti-inflammatory and pain relief, cold compress beauty, sprain, hemostasis, septic, skincare and other physical therapy auxiliaries and perishable products, biological agents and all products that must be transported in a refrigerator (if the ice pack is shipped with the product, it cannot be recovered for reuse. (It is recommended to use the standard double-layer ice bag) Although standard medical is designed for single use, in the careful use of the case, it can also be used many times (Note: but it cannot be compared with HDR-type four-layer ice pack). Its most important feature is to avoid cross-infection caused by patient use.

Ice pack that absorbs water

First, put the ice bag into the water and knead by hand so that the ice expansion technology expansion to about 1cm for the best condition. After the good expansion, remove the dry water surface and then put it in the refrigerator to freeze can be used.

Bio cooling pack

Used and unbroken package of biological cooling packages is cooled in the freezer layer of the refrigerator for at least 12 hours. The liquid inside can be reused when it has completely changed to a solid.

Cooling packs can be kept warm at room temperature for 12-24 hours. Bio ice bag is a polyacrylic polyol polymer refrigerant, an improved alternative to ice with more applicability, and its use is convenient, hygienic and versatile. In addition, reusable ice packs are recycled and eco-friendly.

Put on the biological ice pack into the water and knead by hand so that the ice expansion technology, the expansion to about 1 cm for the best condition, the expansion is well taken out to dry the surface of the water, and finally put in the refrigerator to freeze It may be used.

Precautions for using the cooling pack

The following points should be remembered when using a medical ice pack

1.      Every 10 minutes, observe the skin's condition with cold parts. You must immediately stop using it if there is pale, blue, gray, trembling, pain or numbness.

2.      Pay attention to the cooling protective packaging and the ice capsule whenever there is no leakage. The cloth set must be replaced immediately after watering. Likewise, after the ice melts, it must be replaced promptly.

3.      Cooler pack with cold water slightly more than 1/2 full. Ice bags are too full in the local cold pressure is too high, affecting local blood circulation.

4.      Cooling at the same time can be placed in the heart of the foot-warm water pack to reduce brain tissue congestion, promote heat dissipation and increase comfort.

5.      Ice packs should measure the body temperature 30 minutes after use if used for cooling. After cooling the axillary ice bag, the axillary temperature measurement should not be done within 50 minutes. Because local cold stimulation will cause vasoconstriction, local blood supply is reduced, cell activity is reduced, and temperature is reduced, local 30-60 minutes can return to normal.
