Re-Freez-R-Brix® Cold Bricks are compact, rectangular cold packs engineered with a food-safe, non-toxic phase-change formula sealed in a heavy-duty plastic pouch. Their uniform profile allows efficient stacking and tight packing alongside product in insulated shippers, and the durable pouch construction is built to hold up through the full demands of transit.

These cold bricks are well suited for pharmaceuticals, biologics, lab specimens, meal kit fulfillment, and specialty food shipping — any application where maintaining chilled temperatures over an extended period is critical. They are designed to protect against thawing for up to 12 days, making them appropriate for both short regional runs and longer cross-country shipments.

Each brick is 7.5 oz and measures 4 x 2-1/4 x 1-1/2 inches. Cases contain 48 units and ship via parcel carrier, supporting consistent bulk replenishment for distribution centers, healthcare logistics operations, and cold-chain fulfillment environments.
