Maintaining the appropriate temperature of items is essential during cold-chain transport and storage. There are a variety of cooling and insulation products on the market, of which water bags and gel bags are the two most common cooling media. This paper will compare the characteristics, application scenarios, advantages and disadvantages and their applicability
in different temperature ranges in detail, and introduce the ice bag products provided by our company and their application scenarios and temperature zone.
1. Materials and structures
Water ice bag: water ice bag is mainly composed of plastic bags and water or salt water. Use the water into the plastic bag, then sealed and frozen. The frozen water bags become hard ice cubes, providing lasting low temperatures for items that need to be cooled. This simple structure makes water-injected ice packs cheaper to produce and very convenient to use.
Gel bag: The gel bag is filled with a special gel substance made of sodium polyacrylate, ethylene glycol and other ingredients. The gel bag remains soft after freezing and has a complex design to provide cooling over a wider range of temperatures. Gel bags are usually made of durable plastic or textile materials
to ensure no leakage during freezing and thawing.
2. Temperature control capability
Inilled ice packs: injection ice packs are suitable for cooling requirements below 0℃. Do well in low temperature conditions, can maintain low temperature state for a long time, suitable for long time transportation and storage of items that need to be frozen. Due to the large specific heat capacity of water, the water injection ice bag can provide a stable and lasting cooling effect after freezing.
Gel bag: The gel bag can be controlled in a temperature range from 0℃ to 15℃ by adjusting the internal gel composition. Even after thawing, the gel bag can still maintain a certain cooling effect, which is suitable for items that have low
temperature requirements but need stable cooling for a long time. The temperature control ability of the gel bag is more flexible and can be adjusted according to the specific requirements.
3. Flexibility and application scenarios
Water injected ice packs: Frozen water injected ice packs become hard and have poor flexibility, which are suitable for scenes that do not need accurate fitting, such as food transportation and medical supplies transportation. Due to the large weight after filling with water, the transportation cost is relatively high. In addition, the hardness of water-injected ice packs may cause inconvenience in some applications, but its cooling effect is powerful and suitable for long-term low temperature requirements.
Gel bag: The gel bag remains soft even when freezing and is suitable for items that require a tight fit, such as drug transportation and cold wound compress. The gel bag is lighter, easy to carry and use, and has a wider range of applications. Its softness makes it more protective during transport, especially those that are temperature-sensitive and require smooth transport.
4. Company ice bag product introduction
Shanghai Huizhou Industrial Cold Chain Transportation Technology Co., Ltd. provides a variety of ice bag products, including water injection ice bags and gel bags, which are suitable for different application scenarios and temperature zones respectively. The following is a detailed introduction of our company’s ice bag products and their applicable scenarios and temperature zone.
Water injection ice bag
Main application temperature: below 0℃.
applicable scene:
1. Food transportation: for fresh food, seafood, frozen meat, which need to maintain low temperature for a long time transportation. The strong cooling capacity of waterfilled ice packs ensures that these foods remain fresh during transportation and prevent spoilage.
2. Transportation of medical supplies: suitable for the freezing and transportation of vaccines, blood and other medical supplies. These items have strict temperature requirements, and water injection ice packs can provide a stable low temperature environment to ensure its effectiveness.
3.Outdoor activities: such as picnics, camping, and other occasions requiring the cooling of food and drinks. Inilled ice packs provide lasting cooling during these activities, allowing users to enjoy fresh food and drinks.
Product features:
1. Strong cooling ability: can keep low temperature for a long time, suitable for long time freezing requirements.
2. Low price: low production cost, affordable.
3.Environmental protection: the main component is water, harmless to the environment.
Gel ice bag
Main application temperature: 0℃ to 15℃.
applicable scene:
1. Drug transportation: used for the transportation of drugs, vaccines and other pharmaceutical products with high temperature requirements. Gel bags can provide stable temperature control, ensuring the safety and effectiveness of drugs during transportation.
2. Food storage: Suitable for providing stable cooling effect during food refrigeration and transportation. The softness and temperature control capability of the gel bag make it ideal for food transportation.
3.Daily life: such as cold compress in the family first aid kit, suitable for relieving sprains, burns and other accidental injuries. The gel bag can provide comfortable and effective cold compress in these cases.
Product features:
1. Wide temperature range: By adjusting the gel composition, different temperature ranges can be cooled, with strong applicability.
2. Good softness: remain soft even when frozen, easy to fit items of various shapes.
3. Easy to use: reusable, reduce the replacement frequency, easy to use.
Special purpose ice bag
1. Salt water ice bag
The main application temperature: -30℃ ~0℃. Applicable scenario: frozen food transportation, drug transportation requiring very low temperature environment. Due to their extremely low temperature range, brine ice packs are suitable for the transportation of items with extremely low temperature requirements.
2. Organic phase change material ice bag
The main application temperature: -20℃ ~20℃. Application scenario: Items that need to cool stably over a specific temperature range, such as high-end medicines and special foods. Organic phase change material ice packs can provide stable cooling effect in different temperature ranges for various special requirements.
