Ice-Brix® 48 oz. cold packs deliver reliable refrigeration for temperature-sensitive shipments using a food-safe, non-toxic gel formula that maintains colder temperatures longer than conventional ice. Each pack measures 10 1/4 x 8 x 1 1/2 inches and is built with a flexible, leak-proof outer shell that holds its integrity throughout the freeze-thaw cycle.

These cold packs are widely used by meal kit shippers, specialty food distributors, pharmaceutical fulfillment operations, and biomedical logistics providers. Their flat profile fits cleanly inside standard insulated mailers, foam cooler liners, and corrugated insulated shippers without bunching or shifting during transit.

The reusable design allows packs to be refrozen between shipments, reducing per-shipment refrigerant costs over time. Sold in cases of 6 and ships via parcel.
