I. Major Features of Large Gel Packs for Food and Medicine
Large gel packs are portable refrigeration products used for cooling and preserving heat, widely applicable in fields such as food, medicine, medical first aid, and sports injury cold compresses. These packs contain a special gel that absorbs and releases significant amounts of heat, allowing them to maintain low or high temperatures. They are typically made from durable plastic or other waterproof materials to ensure durability and leak prevention. Key features of large gel packs include:
- Long-term Cooling Preservation: Contains special formula gel that can maintain low temperatures for extended periods, ensuring food and medicine remain within a safe temperature range during transportation.
- Safe and Non-toxic: Made from non-toxic, environmentally friendly materials, making them safe and reliable.
- Multi-purpose: Besides cooling food and medicine, they can also be used for medical emergencies and sports injury cold compresses.
- Soft Plasticity: Retains some flexibility even at low temperatures, allowing it to conform well to various shapes.
- Reusable: High-quality gel packs are durable and can be used multiple times, making them economical and environmentally friendly.
- Multiple Specifications: Available in different sizes and shapes to meet various transportation and refrigeration needs.
- Easy to Clean: The outer layer is typically made of waterproof materials like PEPET or PEPA, making it easy to clean.
- Leak and Damage Resistant: Even if the outer packaging is damaged, the gel inside will not leak, ensuring the integrity of transported items.
II. Types and Advantages of Large Gel Packs
Large gel packs can be classified into different types based on their use, materials, and temperature requirements, each with its own advantages and disadvantages:

- Disadvantages: Longer production cycle, higher cost.
III. Use of Large Gel Packs
Large gel packs are commonly used as refrigerants in cold chain transportation and storage due to their long-lasting cooling capacity and ease of use. Here’s a detailed guide on their use:
- Preparation:
- Choose the appropriate size gel pack based on the required temperature range and storage time.
- Pre-freeze the gel pack by placing it in a freezer below -18°C for at least 12-24 hours to ensure it is fully frozen.
- Steps for Use:
- Confirm the freeze status: Check that the gel pack is fully frozen before use. A fully frozen gel pack should be hard and free of liquid flow.
- Prepare cold-chain containers: Ensure the cold chain containers (like coolers or insulated bags) are clean and ready for use.
- Arrange the gel packs: Place the gel packs in appropriate positions within the cold chain container, typically around or above/below the items to ensure uniform cooling.
- Package the items: Place temperature-sensitive items in the cold chain container and secure them with buffer materials (e.g., bubble wrap, foam) to prevent movement and damage.
- Seal the container: Close and seal the container properly to maintain a stable internal temperature.
- Precautions:
- Avoid direct contact with sensitive items by using isolation layers (e.g., cardboard, foam).
- Monitor the temperature during transportation using a temperature recorder to ensure it remains within the desired range.
- Check the integrity of the gel packs regularly to prevent leakage.
IV. Temperature Control and Environmental Impact of Large Gel Packs
- Temperature Control:
- Cold Retaining Temperature Range: Typically maintains a temperature range of 0°C to 10°C, suitable for most food and pharmaceutical refrigeration needs.
- Duration: Cold retention time varies by type and usage; standard gel packs retain cold for several hours, while high-performance packs can last for tens of hours.
- Usage: Pre-freezing is essential (8-12 hours in a freezer) for optimal performance. Temperature monitoring is recommended for items requiring strict control.
- Environmental Impact:
- Eco-friendly Materials: Selecting environmentally friendly and reusable gel packs can meet refrigeration needs while minimizing environmental impact. Proper disposal and maintenance further reduce environmental pressure.
