How to Use Large Gel Packs

Large gel packs are commonly used as refrigerants in cold chain transport and storage, due to their ability to maintain low temperatures for extended periods and their ease of use. They are widely applied in the cold chain transport of food, pharmaceuticals, biological products, and other temperature-sensitive items. Below are detailed instructions on how to use large gel packs:

1. Preparation
   • Select the Right Size and Type: Choose the appropriate size and type of gel pack based on the required temperature range and storage duration.
   • Pre-Freeze: Place the gel pack in a freezer at -18°C or lower for 12-24 hours to ensure it is fully frozen.
2. Steps for Use
   • Confirm Freezing: Before use, check if the gel pack is completely frozen. A fully frozen pack should be solid and free of liquid movement.
   • Prepare the Cold Chain Container: Ensure that the cold chain container (such as an insulated box or bag) is clean and undamaged, and prepare the items for transport.
   • Position the Gel Packs: Place the gel packs appropriately around the items in the cold chain container, typically around the sides or on the top and bottom, to ensure even cooling.
   • Pack the Items: Place temperature-sensitive items in the container, using appropriate cushioning materials (like bubble wrap or foam) to prevent movement and damage during transport.
   • Seal the Container: Close and seal the container securely to maintain internal temperature stability.
3. Important Considerations
   • Avoid Direct Contact: Some pharmaceuticals or biological products are highly sensitive to low temperatures. Use a barrier layer (like cardboard or foam) to prevent direct contact with the gel pack.
   • Monitor Temperature: During transport, use a temperature recorder or monitoring device to track temperature changes and ensure it remains within the required range.
   • Check for Leaks: Regularly inspect the gel pack for damage or leaks. Replace any damaged packs immediately.
   • Reusable: Gel packs can be reused, but ensure they are fully refrozen before each use and check for any damage.

Temperature Control and Environmental Impact of Large Gel Packs

Large gel packs offer several key features in temperature control and environmental impact:

1. Temperature Control
   • Cooling Range: Generally maintains temperatures between 0°C and -10°C, suitable for most cold storage needs of food and pharmaceuticals.
   • Duration: The cooling duration varies depending on the type of gel pack and the environmental conditions. Standard gel packs typically maintain low temperatures for several hours, while high-performance packs can last for tens of hours under optimal conditions.
   • Usage Method: Gel packs require pre-cooling in a freezer for 8-12 hours before use for optimal performance.
   • Temperature Monitoring: For items requiring strict temperature control, it is recommended to use temperature recording devices to ensure that the temperature remains within a safe range during transport and storage.
2. Environmental Impact
   • Eco-Friendly Materials: Choose environmentally friendly and reusable gel packs to meet cooling needs while minimizing environmental impact.
   • Proper Disposal: Follow local regulations for disposing of used gel packs to reduce environmental pollution.
   • Safe Storage: Store gel packs in a location that is out of reach of children and pets to prevent accidental ingestion or misuse.
