From life sciences and perishables to specialty Cold Chain applications, Cold Ice delivers advanced temperature- control solutions, including premium Gel and Foam Refrigerants, Insulated Shipping Containers and Temperature Monitoring Tools backed by over 40 years of manufacturing expertise.
We’ve been making our own gel & foam refrigerants at our Oakland, California facility since 1982. When you control production in-house, you control consistency, and in cold chain, consistency is everything. Add our responsive service, commitment to sustainability, and decades of hands-on expertise, and you’ve got a partner, not just a supplier.
A comprehensive selection of refrigerants, packaging, and monitoring. Everything you need to build a consistent cold chain, from a single source.
Leak proof, plant-based gel refrigerants engineered for premium cooling.
Insulated shipping boxes, pouches, & liners that protect your shipment.
Temperature monitoring solutions that provide added security for your payload.
Use TheraFlex for both HOT and COLD therapeutic relief. Hot or cold, dual purpose TheraFlex maintains an even temperature over the entire pad.
TheraFlex® Hot and Cold Therapy Packs are made for therapeutic use. This reusable therapy pack delivers targeted hot or cold relief for physical therapy, sports recovery, home care, and clinical settings.

Cold Chain Expertise
Four decades of cold chain manufacturing experience, applied to whatever your shipment needs.
Place refrigerant packs on multiple sides of the product, not just on top, and avoid air gaps. Fill the space with appropriate dunnage to reduce air movement and keep the product centered and away from the container, and use enough refrigerant for the duration of the shipment and the expected ambient temperatures. For critical shipments, verify performance with temperature indicators or data loggers.
The type of refrigerant depends on the product’s temperature requirements and shipping conditions.
Freezing time depends on pack size, freezer temperature, airflow, and the quantity being frozen. An individual 24-ounce gel pack may freeze in approximately 8 to 12 hours.
For faster freezing, separate gel packs or cases; this will allow airflow around each pack or case, resulting in a faster freeze time.Full pallets can take weeks to freeze depending on freezer capacity and airflow. The center of the load freezes last.
This issue can be eliminated by using a leak-proof semi-solid gel refrigerant such as Cold Ice that is designed not to leak if the wrapper is punctured or torn, unlike free-flowing gels that will leak.
Yes, high-quality gel refrigerant packs are designed for multiple uses. Cold Ice gel refrigerants can be refrozen and reused multiple times.
Use temperature monitoring tools to verify cold chain performance throughout transit. Cold Ice provides temperature indicators and monitors that help track shipping conditions and document that the products arrive in the required temperature range.
No. Most gel packs will leak. Cold Ice gel packs are designed with cross-linked semi-solid hydrogel technology, where the gel will not leak if the wrapper is punctured or torn.
