A gel pcm pack is a flexible thermal control product filled with phase change materials dispersed in a gel matrix. Compared with rigid PCM cooling packs, gel packs offer improved flexibility and surface contact, making them suitable for applications requiring close thermal coupling and ergonomic design.
Gel pcm packs are widely used in cold chain transport, medical packaging, personal cooling products, and wearable thermal solutions.
Size(mm): Customizable
Standard temperatures: 15°C/18°C/23°C/25°C
Custom temperatures available: 2~28°C

Whether you need a compact cooling insert for a smartphone, a wearable cooling vest insert, or a large gel pack for cold chain transportation, PCMCOOL can manufacture it to your specifications.
PCMCOOL provides custom Gel PCM pack solutions, including:
Gel PCM packs store and release thermal energy through the latent heat of phase change. The gel carrier improves heat transfer efficiency and allows the pack to conform to surrounding surfaces, enhancing temperature stability.

How To Use?
Gel PCM Packs should be used along with insulation shipping boxes.
①Pre-cooling Preparation: Before use, place the PCM pouches/Gel Packs in a for a certain time to ensure complete freezing;
②Placement Method: Evenly lay the frozen pouches on the bottom and surrounding inner walls of the insulated container, ensuring all surfaces of the container are fully covered to form a full-wrap insulation protection;
③Cargo Placement: Put the goods in the center of the insulated container, then place the PCM pouches/Gel Packs on top of the goods, and close the insulated container;
④Extension of Cooling Duration: If it is necessary to extend the transportation time, additional PCM pouches/Gel Packs of the corresponding quantity can be added on the existing basis, or larger-sized products can be selected;
⑤Reuse: After use, wait for the cold storage bag to thaw naturally, wipe off surface stains, and it can be reused after re-freezing.
